Driver Seat Module - Memory Seat

Note. The memory seat track position sensors are integral to the memory seat track motors. The memory seat track motor electrical connectors will connect to a seat track without the memory option. Make sure the correct seat track is being installed.

The power driver seat, power outside rear view mirrors and power adjustable pedals (if equipped) are controlled by the driver seat module (DSM) if the vehicle is equipped with the programmable/recall memory option. The DSM is located underneath the driver seat.

This system allows automatic positioning of the driver seat, power outside rear view mirrors and power adjustable pedals (if equipped) to 2 programmable positions. Memory positions can be stored at any time. A memory recall can be initiated only if the vehicle is in PARK or NEUTRAL gear and the ignition switch is not in START. A memory recall in progress will not be affected by moving the ignition switch to START or by moving the gearshift lever out of PARK or NEUTRAL. For information on programming memory positions or recalling a stored memory position, refer to Memory Position Programming .

Easy Entry/Easy Exit

The memory driver seat easy entry/exit feature moves the seat slightly rearward for easier exit from the vehicle and returns the seat forward after entry. The easy entry/exit feature can be enabled/disabled using the selections on the message center. Refer to Principles of Operation in this article or the Owner's Literature.

Front Heated Seats

This system allows the electrical heating of the front seats on passenger demand.

The components of the system are

1. the seat heater mats located in the front seat cushions and backrests.
2. the heated seat module located underneath the front passenger seat.
3. the driver and passenger front heated seat switches, located on the climate control assembly.
4. the temperature sensors, located in the seat cushion heater mats.

Power Recliner

The driver and passenger front seat can be equipped with electro-mechanical backrest adjusters. The backrest adjustment switch is located on the side of the seat cushion side shield and is part of the seat control switch. The recliner assembly is mounted to the seat cushion frame and backrest latch assembly.

Manual Lumbar

The manual front seat backrest lumbar and handle is mounted to the side of the seat backrest frame. The manual lumbar actuator rotates, pulling a cable, to move the backrest lumbar in or out.

Seat Side Air Bag

Note. If a side air bag deployment took place, a new seat back pad, trim cover and side air bag module and nuts must be installed. A new seat back frame should be installed if necessary.

The driver and passenger seat side air bags are attached to the seat backrest frame. If a seat side air bag deployment has occurred or for more information, refer to the appropriate procedure in SUPPLEMENTAL RESTRAINT SYSTEM article.

Safety Belt Buckle Pretensioners

As part of the supplemental restraint system (SRS), the driver and passenger front seat safety belt buckles are equipped with pretensioners. The safety belt buckle pretensioner assemblies are attached to the seat tracks. The safety belt buckle pretensioners remove excess slack from the safety belt webbing and are activated by the restraints control module (RCM) when the module detects a collision event force exceeding a programmed limit. For information or if a deployment has occurred, refer to the appropriate procedure in SUPPLEMENTAL RESTRAINT SYSTEM article.

Occupant Classification Sensor (OCS) System

Note. Occupant classification sensor (OCS) system components (seat cushion foam pad, bladder with pressure sensor and occupant classification system module [OCSM]) are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a new OCS system, OCS system component or seat cushion foam pad are needed, a new OCS system service kit (seat cushion foam pad, bladder with pressure sensor, OCSM and seat wiring harness) must be installed as an assembly.

Note. To identify between a production OCS system and an OCS system service kit, inspect the OCSM electrical connector. A production OCS system allows the disconnection of the OCSM electrical connector. An OCSM system service kit has the electrical connector glued to the OCSM, it cannot and should not be disconnected or altered. An OCS system service kit also has an in-line connector between the OCSM and the seat wiring harness.

The OCS system is standard equipment on all front outboard passenger seats. For information on diagnosing or servicing the OCS system, refer to SUPPLEMENTAL RESTRAINT SYSTEM article.

Taurus and Sable

These seats have a 60/40 split backrest. The 60 percent has a fold down armrest. Each backrest is held in place at the top with its own striker attached to the package tray sheet metal and a latch attached to each backrest frame.

Taurus X

There are 3 seating options for the second row: a 60/40 or a 40/40 and a power-fold 40/40. All seats will fold forward to ease entry to the third row of seating (E-Z entry). Each configuration's backrests will recline and fold flat. The manual 40/40 seats have an optional adjustable seat track in place of the stationary riser. The power-fold 40/40 seats are equipped with optional heated seat systems.

Power-fold Seats

The optional power-fold Taurus X seats have convenient power-fold seat control switches mounted in each rear quarter trim panel beside the seat backrest. When the power-fold seat control switch is depressed and held for a moment, an electro-mechanical motor releases that seat's recliners and latch feet, through a cable attachment. An assist spring in the backrest recliner folds the backrest to the fold-flat position and a spring assist strut folds the seat to the E-Z entry position. The seat must be manually returned to the seating position.

Rear Heated Seats

This system allows independent seat electrical heating of each rear power-fold seat on demand.

The components of the system are

1. the seat heater mats located on the seat cushion and backrest.
2. the heated seat module located underneath the front floor console.
3. the heated seat switches, located on the floor console rear panel.
4. temperature sensors, located in the seat cushion heater mats.

A new heater mat will come assembled on a new foam pad.

Third Row Seating

There are 2 seating options for the third row; a bench seat or 50/50 split bench seat is available. Both seats will fold flat into the floor, forming a load floor for carrying cargo.

Scheme 1

Scheme 2

Driver and Passenger Power Seats Without Memory

The driver power seat uses a 6-way power seat track and 3 electric motors directly controlled by a seat mounted 6-way seat control switch for horizontal (forward/rearward), front height and rear height adjustment. The passenger seat uses a 2-way seat track with a single electric motor and is directly controlled by a 2-way seat mounted seat control switch for horizontal adjustment. Both driver and passenger seats can also be equipped with a power recliner mechanism, which uses a single electric motor and is also directly controlled by an 8-way seat control switch (driver seat) or a 4-way seat control switch (passenger).

The driver and passenger power seat and power recliner motors are hard-wired to the seat control switch. The circuits are normally at ground through the seat control switch. An individual motor is switched to voltage and ground when a specific adjustment position is selected. The power seat feature operates independent of the ignition switch position.

Driver Power Seat With Memory

Note. A memory recall can be initiated only if the vehicle is in PARK or NEUTRAL gear and the ignition switch is not in START. A memory recall in progress will not be affected by moving the ignition switch to START or by moving the gearshift lever out of PARK or NEUTRAL.

Note. Verify good battery condition before diagnosing the memory seat system. Poor battery condition may interfere with memory seat operation, even if vehicle starting is possible.

The memory driver seat feature allows the driver to program a personalized seat position that can be recalled using the memory switch or a remote keyless entry (RKE) transmitter (if associated). There are 2 memory settings possible. The outside rear view mirror positions and power adjustable pedals position are also stored and recalled with the power driver seat positions. For information on programming memory positions or recalling a stored memory position, refer to Memory Position Programming .

The driver power seat is controlled by the driver seat module (DSM), if equipped. The DSM is located underneath the driver seat cushion frame. Programmable module installation (PMI) must be carried out when installing a new DSM. Refer to MODULE CONFIGURATION article. The DSM does not require calibration to the driver seat track.

The driver seat control switch provides voltage to the DSM when activated. The neutral position of each driver seat control switch position is a ground state through the seat control switch contacts. A voltage input causes the DSM to power the appropriate motor until the input is removed. Ground is the normal state of the motor circuits through the DSM and is not switched to control the motors. The DSM internally switches the appropriate circuit from ground to power for operating the motors.

As the seat is adjusted, the DSM constantly monitors the motor position sensors to record the current seat position. The DSM will remove power from the motor upon termination of the seat control switch input or if the DSM does not see movement from the motor by monitoring the position sensor.

The DSM has the ability for soft stops both at the upper and lower limits on all axis of the driver seat. When an axis reaches the hard stop and the switch is held for approximately one second it will then back up 180 msec and establish the soft stop for that axis in that direction. The DSM uses this 'back up' strategy to check sensor integrity any time movement has stopped prematurely due to a sensor failure or obstruction.

The DSM communicates DTC and other information using the medium-speed controller area network (MS-CAN) communication bus. It should be noted for diagnostics that because controller area network (CAN) bus communication is more robust and reliable than other methods, it may be possible to have limited module communication with one of the CAN bus circuits disconnected or shorted to ground. Refer to MODULE COMMUNICATIONS NETWORK article for additional information concerning MS-CAN bus communication.

This article only diagnoses concerns specific to the memory seat. To diagnose a memory power mirror concern, refer to REAR VIEW MIRRORS article. To diagnose a power adjustable pedal concern, refer to BRAKE SYSTEM - GENERAL INFORMATION article.

Remote Keyless Entry (RKE) Transmitter

A remote keyless entry (RKE) transmitter can be used to recall previously set memory positions but must first be associated to that memory position. The transmitter associated with personality 1 is capable of recalling memory position 1 only. Similarly, the associated personality 2 transmitter can recall only memory position 2. Up to 8 RKE transmitters can be associated for memory position recall.

Memory recall occurs when the unlock switch is depressed on the RKE transmitter if it has been associated with a memory position. The second depression of the unlock switch, which unlocks passenger doors, does not initiate a memory recall.

A memory recall in progress does not prohibit the initiation of another memory recall; the most recently requested memory recall will be executed.

To associate a remote transmitter to a memory position, refer to Remote Keyless Entry Transmitter Programming in HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS article. To diagnose a RKE transmitter concern, refer to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS article.

Easy Entry/Exit Feature

The easy entry/exit feature moves the seat backwards about 2 inches when the ignition key is removed from the ignition switch. The DSM receives a key out command over the MS-CAN communication network and powers the driver seat rearward. This function will not operate if the seat is less than the travel distance to the end of the track or the function has been disabled. The DSM will also cancel this operation if a valid input command is received, such as the seat control switch or memory recall request.

The DSM will record the current seat position before powering the seat for an easy exit operation. This recorded position will be used to return the seat to this position on the easy entry operation. During easy entry operation, the seat is returned to the position previous to the easy exit operation. Easy entry operation will be cancelled if a valid input command is received by the DSM.

The easy entry/exit feature can be disabled and enabled by selecting easy entry on the message center display with the setup control button and pressing the reset control to select on or off from the display menu. Refer to driver controls in the Owner's Literature for additional instructions for using the message center.

Heated Seats - Front

Note. Do not install a new heater mat on a front passenger seat cushion. If a new cushion heater mat is needed on the front passenger seat, an occupant classification sensor (OCS) service kit equipped with a heater mat must be installed. Failure to follow this instruction may result in incorrect operation of the OCS system. Refer to SUPPLEMENTAL RESTRAINT SYSTEM article for the OCS removal and installation procedure.

The heated seat system is controlled by the heated seat module located underneath the front passenger seat cushion. The heated seat switches are part of the HVAC module but the heated seat system operates independently from the climate control system. The heated seat module supplies voltage to heater mats located in the seat cushion and backrest to heat the seat. The heated seat module regulates seat temperature by monitoring resistance of a thermistor type thermostat located in the cushion heater mat. The heated seat module is designed to remain on, heating the seat and maintaining temperature until switched off or a 10-minute time-out period occurs.

Normal heat cycle may require several minutes to initially warm the seat. The seat should be occupied to correctly test for normal operation. Temperature measuring devices do not provide an accurate method for testing heated seat operation as surface temperatures are subject to human and environmental characteristics. Correct testing requires heater mat resistance measurements which have tight tolerances affecting the length of time for the heater mats to reach maximum operating temperature.

The heated seat module monitors the heater output and thermistor circuits for fault detection but does not report DTCs and is not connected to the communication bus circuits. If an open circuit or short to ground occurs, the output is disabled to the heater mats and the heated seat indicators turn off. When a fault is detected the heated seat module only disables the affected seat and the other seat will continue to operate normally. While disabled, the heated seat indicators will flash once with each button press and the heated seat cannot be operated until the system is repaired. After the repair is made, the ignition must be cycled OFF to reset the heated seat module from the detected fault.

Heated Seats - Rear (Taurus X)

Rear heated seats are controlled by a heated seat module and heated seat switches located in the front console. When a heated seat switch is pressed and ignition ON, a momentary ground signal is sent to the heated seat module. The heated seat module then supplies voltage to the heater circuit. The seat cushion and backrest heater mats are wired in series. The heated seat module monitors inputs from a temperature sensor, located in each seat's cushion heater mat and maintains seat temperature by cycling the heater output as necessary to maintain the setpoint temperature. The heated seat module also outputs voltage to the appropriate indicator circuit in the heated seat switch indicating the system is on. The heated seat module remains on until the heated seat switch is pressed a second time in that mode or the ignition switch is cycled OFF.

If a fault is detected by the heated seat module, the module will stop supplying power to that individual left or right seat as well as the switch indicator on which that fault was detected. The faults detected will be: a heater feed circuit short to battery, ground or open; sensor circuit short to battery or open; heated seat switch stuck closed to ground or heated seat switch low and high inputs shorted together. To reset the module, cycle the ignition switch OFF and then ON. After the heated seat module has been reset, the module will return to an off state. The heated seat module does not report DTCs and does not communicate on any communication network.

Second Row Power-Fold Seat (Taurus X)

Note. The smart junction box (SJB) may also be identified as generic electronic module (GEM).

For the second row power-fold seat to operate, voltage is supplied by the SJB to the power-fold seat relay, enabling the seats to then be moved by pressing the second row power-fold seat switch.

The power-fold seat relay will be provided voltage on the coil side from the SJB for 30 minutes when the transmission selector is in PARK, and the liftgate, or liftgate glass, is open. The voltage will be disabled 30 minutes after turning the vehicle OFF. If the relay is disabled after 30 minutes, it can be enabled by opening any door, pressing the unlock key on the key fob, pressing any keyless keypad button or turning the ignition key.

The second row power-fold seat motor retracts a cable to release the backrest recliner latches and allows the backrest assist spring to fold the backrest forward onto the seat cushion. The power-fold seat motor continues to retract to release the seat-to floor latches and allows the spring assist strut to lift and tumble the seat forward to the E-Z entry position for 3rd row seat access. Immediately after the seat is fully released, the power-fold seat motor returns the release cable and latches to a relaxed state, ready for manual latching. To return to a seating position, the seat must be manually latched to the floor and the backrest must be manually latched upright.

Second Row 60/40 Percent E-Z Entry Seats (Taurus X)

Note. The backrest must be folded flat (fully downward) before the floor latches can be released. Make sure there are no objects on the seat before lowering the backrest(s). Failure to follow this instruction may cause damage or incorrect operation of the seat.

The 60/40 E-Z entry seats have the following 3 functional positions

1. Backrest fold-flat
2. E-Z entry (fold-forward position for third row access)
3. Upright

For backrest fold-flat position, lower the head restraint, pull the release strap or recliner handle up and fold the backrest fully downward. To return upright (seating position), pivot and raise the backrest toward the rear of the vehicle until locked upright (vertical) for occupancy.

For E-Z entry, move the backrest to the fold-flat position and pull the release strap or recliner handle a second time to release the floor latches. Turn the recliner handle or pull the third row occupant release strap a second time until the seat releases from the latch strikers. Lift up on the rear of the seat, pivoting it forward, away from the third row seats and up to the E-Z entry position. To return the seat, push the rear of the seat down with moderate force to latch the seat to the strikers. Make sure the seat is latched to the strikers by lifting up on the rear of the seat. Lift and pivot the top of the backrest toward the rear of the vehicle, rotating the backrest until you hear a click, locking it in the upright (vertical) position. Make sure the seat backrest is locked in position.

For access to the third row seats through the rear doors, fold the seat up out of the way (E-Z entry position), after the backrest has been folded down. To release the latch feet from the strikers and position the seat to the E-Z entry position, the backrest must be folded forward and all the way down. Remove anything between the backrest and cushion that may prevent the backrest from folding all the way down.

Pinpoint Test D: The Power Seat is Inoperative - Passenger, Without Power Recliner

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Power Seats for schematic and connector information.

The passenger seat control switch is powered by battery voltage to the passenger seat control switch, circuit SBB21 (GY/RD), and is supplied ground on passenger circuit GD148 (GK/YE). When pressed, the seat control switch supplies that voltage and ground to the power seat track motor to move the seat. When pressed in the opposite direction, the seat control switch reverses the polarity to the power seat track motor, which moves the seat in the opposite direction. There is one power seat track motor which moves the seat horizontally (forward/rearward). If a new motor needs to be installed, it is necessary to install an entire power seat track.

This pinpoint test is intended to diagnose the following

1. Fuse
2. Wiring, terminals or connectors
3. Seat control switch
4. Power seat motor (seat track)

Pinpoint Test F: The Power Seat Does Not Move Horizontally/Vertically - Driver, Without Power Recliner

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Power Seats for schematic and connector information.

The driver seat control switch is powered by battery voltage on driver circuit SBB32 (VT/RD) and is supplied ground on circuit GD147 (BK/VT). When pressed, the seat control switch supplies that voltage and ground to a power seat track motor to move the seat. When pressed in the opposite direction, the seat control switch reverses the polarity to that same power seat track motor, which moves the seat in the opposite direction. There are 3 power seat track motors that combine to move the seat cushion horizontally (forward/rearward) and vertically (front up/down and rear up/down).

Pinpoint Test K: The Memory Seat is Inoperative/Does Not Operate Correctly - Does Not Operate Horizontally/Vertically/Recline

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Memory Seats for schematic and connector information.

Refer to appropriate appropriate COMPONENT TESTING article article.

The driver seat control switch is powered by battery voltage on circuit SBP12 (GN/RD) and is supplied ground on circuit GD147 (BK/VT). When pressed, the seat control switch supplies the voltage and ground to the applicable driver seat module (DSM) inputs. The DSM then supplies voltage and ground to the appropriate power seat track motor or power recline motor based on the inputs received from the seat control switch. When pressed in the opposite direction, the seat control switch reverses the polarity to the DSM inputs, and the DSM likewise reverses polarity of the appropriate power seat track motor or power recliner motor circuits causing the seat or backrest to move in the opposite direction. There are 3 power seat track motors that combine to move the seat horizontally (forward/rearward) and vertically (front up/down and rear up/down). The seat backrest power recliner mechanism uses a single motor to move the seat backrest forward and rearward.

Battery voltage is also supplied to DSM on circuit SBB32 (VT/RD) and SBP12 (GN/RD). Ground is supplied to the DSM on circuit GD147 (BK/VT).

Each motor, in the memory power seat track and power recliner mechanism contains a Hall-effect position sensor. The DSM supplies a shared signal feed circuit to each position sensor. Each position sensor sends a signal pulse back to the DSM used to monitor the position of the power seat and seat backrest. The DSM uses this information to return the seat to a stored pre-programmed position when pressing the memory SET switch or a remote entry transmitter. For information on programming memory positions or recalling a stored memory position, refer to Memory Position Programming .

The following pinpoint test diagnoses a memory seat that does not operate in one or more directions when using the seat control switch. If the seat does move in all directions using the seat control switch or operates in 1-second intervals, Go to Pinpoint Test L .

This pinpoint test is intended to diagnose the following

1. Fuse
2. Wiring, terminals or connectors
3. Seat control switch
4. Missing status information (controller area network [CAN] communication bus messages): Ignition switch status Gear selector position
5. Seat track
6. Power recliner mechanism
7. DSM

Note. The air bag warning indicator illuminates when the correct restraints control module (RCM) fuse is removed and the ignition switch is ON.

Note. The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

Note. The memory seat track position sensors are integral to the memory seat track motors. The memory seat track motor electrical connectors will connect to a seat track without the memory option. When installing a new seat track, make sure the correct memory or non-memory seat track is being installed.

Note. If a new DSM is installed, the driver seat, memory mirrors and power adjustable pedals (if equipped) must be operated in all directions through the full range of travel to avoid a premature stopping point occurrence after the vehicle is returned to the customer.

Note. Verify good battery condition before diagnosing the memory seat system. Poor battery condition may interfere with memory seat operation, even if vehicle starting is possible.

Pinpoint Test L: The Memory Seat Does Not Operate Correctly - Does Not Operate Using the Memory SET Switch

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Memory Seats for schematic and connector information.

The driver seat control switch is powered by battery voltage on circuit SBP12 (GN/RD) and is supplied ground on circuit GD147 (BK/VT). When pressed, the seat control switch supplies the voltage and ground to the applicable driver seat module (DSM) inputs. The DSM then supplies voltage and ground to the appropriate power seat track motor or power recline motor based on the inputs received from the seat control switch. When pressed in the opposite direction, the seat control switch reverses the polarity to the DSM inputs, and the DSM likewise reverses polarity of the appropriate power seat track motor or power recliner motor circuits causing the seat or backrest to move in the opposite direction. There are 3 power seat track motors that combine to move the seat horizontally (forward/rearward) and vertically (front up/down and rear up/down). The seat backrest power recliner mechanism uses a single motor to move the seat backrest forward and rearward.

Battery voltage is also supplied to DSM on circuit SBB32 (VT/RD) and SBP12 (GN/RD). Ground is supplied to the DSM on circuit GD147 (BK/VT).

Each motor, in the memory power seat track and power recliner mechanism contains a Hall-effect position sensor. The DSM supplies a shared signal feed circuit to each position sensor. Each position sensor sends a signal pulse back to the DSM used to monitor the position of the power seat and seat backrest. The DSM uses this information to return the seat to a stored pre-programmed position when pressing the memory SET switch or a remote entry transmitter. For information on programming memory position or recalling a stored memory position, refer to Memory Position Programming .

The following pinpoint test diagnoses a memory seat that does not operate correctly using the memory SET switch or operates in 1-second intervals. If the memory seat does not move in all directions using the seat control switch, Go to Pinpoint Test K .

This pinpoint test is intended to diagnose the following

1. Fuse
2. Wiring, terminals or connectors
3. Remote keyless entry (RKE) transmitter
4. Memory SET switch
5. Missing status information (controller area network [CAN] communication bus messages): Ignition switch status Gear selector position
6. Seat track
7. Power recliner mechanism
8. DSM

Note. The air bag warning indicator illuminates when the correct restraints control module (RCM) fuse is removed and the ignition switch is ON.

Note. The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

Note. The memory seat track position sensors are integral to the memory seat track motors. The memory seat track motor electrical connectors will connect to a seat track without the memory option. When installing a new seat track, make sure the correct memory or non-memory seat track is being installed.

Note. If a new DSM is installed, the driver seat, memory mirrors and power adjustable pedals (if equipped) must be operated in all directions through the full range of travel to avoid a premature stopping point occurrence after the vehicle is returned to the customer.

Note. Verify good battery condition before diagnosing the memory seat system. Poor battery condition may interfere with memory seat operation, even if vehicle starting is possible.

Pinpoint Test N: The Heated Seat is Inoperative/Does Not Operate Correctly - Driver

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Climate Controlled Seats for schematic and connector information.

The heated seat module receives ignition voltage on circuit CBP35 (YE/GY), battery voltage on circuit SBB22 (BN/RD) and is supplied ground on circuit GD148 (BK/YE). With the ignition ON and the driver heated seat button pressed, a momentary ground signal is sent from the HVAC module to the heated seat module on circuit CHS29 (WH/BU) to request the system on or off. The heated seat will decrease one setting with each button press (the sequence is high, low, off, high, etc.). The heated seat module supplies voltage to the cushion and backrest heater mats on heater circuit CHS02 (YE/BU). Ground to the heater mats is provided on circuit GD147 (BK/VT). The cushion and backrest heater mats are connected in series and operate together. The heated seat module regulates seat temperature by monitoring resistance of a thermistor type thermostat (part of the cushion heater mat) connected on circuits VHS26 (VT) and RHS05 (YE/VT). The heated seat module is designed to remain on, heating the seat and maintaining temperature until switched off.

The heated seat module monitors the heater output and thermistor circuits for fault detection but does not report DTCs and is not connected to the communication bus circuits. If an open circuit or short to ground occurs, the output is disabled to the heater mats and the heated seat indicators turn off. When a fault is detected, the heated seat module only disables the affected seat. While disabled, the heated seat indicators will flash once with each button press and the heated seat cannot be operated until the system is repaired. The ignition must be cycled OFF to reset the heated seat module from the detected fault.

This pinpoint test is intended to diagnose the following

1. Fuse(s)
2. Wiring, terminals or connectors
3. Backrest or cushion heater mat
4. Heated seat module
5. HVAC module

Note. The air bag warning indicator illuminates when the correct restraints control module (RCM) fuse is removed and the ignition is ON.

Note. The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test O: The Heated Seat is Inoperative/Does Not Operate Correctly - Front Passenger

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Climate Controlled Seats for schematic and connector information.

The heated seat module receives ignition voltage on circuit CBP35 (YE/GY), battery voltage on circuit SBB22 (BN/RD) and is supplied ground on circuit GD148 (BK/YE). With the ignition ON and the passenger heated seat button is pressed, a momentary ground signal is sent from the HVAC module to the heated seat module on circuit CHS30 (GY/YE) to request the system on or off. The heated seat will decrease one setting with each button press (the sequence is high, low, off, high, etc.). The heated seat module supplies voltage to the cushion and backrest heater mats on heater circuit CHS07 (GY/BU). Ground to the heater mats is provided on circuit GD148 (BK/YE). The cushion and backrest heater mats are connected in series and operate together. The heated seat module regulates seat temperature by monitoring resistance of a thermistor type thermostat (part of the cushion heater mat) connected on circuits VHS27 (WH/OG) and RHS05 (YE/VT). The heated seat module is designed to remain on, heating the seat and maintaining temperature until switched off.

The heated seat module monitors the heater output and thermistor circuits for fault detection but does not report DTCs and is not connected to the communication bus circuits. If an open circuit or short to ground occurs, the output is disabled to the heater mats and the heated seat indicators turn off. When a fault is detected, the heated seat module only disables the affected seat. While disabled, the heated seat indicators will flash once with each button press and the heated seat cannot be operated until the system is repaired. The ignition must be cycled OFF to reset the heated seat module from the detected fault.

This pinpoint test is intended to diagnose the following

1. Fuse(s)
2. Wiring, terminals or connectors
3. Backrest or cushion heater mat
4. Heated seat module
5. HVAC module

Note. The air bag warning indicator illuminates when the correct restraints control module (RCM) fuse is removed and the ignition is ON.

Note. The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test R: The Power Seat is Inoperative/Does Not Operate Correctly - Second Row, Power-Fold

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Power Seats for schematic and connector information.

Each second row power-fold seat receives battery voltage from the smart junction box (SJB) circuit SBP18 (YE/RD) (hot at all times) and is connected to ground. The power-fold seat motors contain internal switching that operate the motor until it moves to the reset position and turns off. The demand lighting/battery saver voltage output circuit CLN09 (YE/GN) from the SJB provides the control signal voltage to each seat control switch. The seat control switches are momentary contact switches when pressed and held for at least one second supply switched voltage to the power-fold seat motor control circuit CPS56 (GN/BN) or CPS57 (GY/BN) to initiate a pull and release cycle. The power-fold seat motor retracts a release cable connected to the same mechanical release lever in the seat latch mechanism as the manual release pull strap. When the power-fold seat motor is cycled, the pull strap retraction and release/reset will be noticeable.

This pinpoint test is intended to diagnose the following

1. Fuse(s)
2. Wiring, terminals or connectors
3. Power-fold switch
4. Power-fold seat actuator

Note. Make sure the second row power-fold seats will manually release and latch before troubleshooting the electrical system.
