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 are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located underneath the driver seat cushion.

Note. During reflash, if the flash operation fails, disconnect the battery for 30 seconds, then reconnect the battery and continue.

This system allows automatic positioning of the driver seat to 2 programmable positions.

1. A power driver seat position can be stored at any time. The driver must move the seat to the desired position using the driver seat switch assembly. The driver must then depress the memory SET switch which activates the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out), the driver must select a memory position. Memory 1 is selected by depressing memory switch 1. Memory 2 is selected by depressing memory switch 2.
2. If no memory switch input is received within the 5-second time limit, the operation is aborted and the memory SET switch LED is turned off. This also occurs if one of the following inputs is received during the 5-second programming limit: Power driver seat switch Memory SET switch Power adjustable pedal switch

A position can only be recalled when the transmission selector is in PARK or NEUTRAL. A position may be programmed at any time.

Heated Seats

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

The components of the system are

1. the seat heating elements located in the seat cushion and backrest.
2. the heated seat module located on the seat cushion pan.
3. the heated seat control switch, located on the electronic automatic temperature control (EATC) module.
4. the temperature sensor, located in the seat cushion heating element.

Restraint System Diagnostic Tool Warning

Diagnostic Tool and Controller Area Network Note

Note. This vehicle utilizes a communication system called a medium-speed controller area network (MS-CAN). When diagnosing the driver seat module and memory seat system use the Worldwide Diagnostic System (WDS) and the latest software update or equivalent diagnostic tool with the capability of communicating over the MS-CAN bus.

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 power circuit 566 (DG) (driver seat) or circuit 1462 (RD/WH) (passenger seat) and ground circuit 1205 (BK) when a specific adjustment position is selected. The power seat feature operates independent of the position of the ignition switch.

Power Driver Seat With Memory

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. There are 2 memory settings possible. The outside rear view mirror positions and the power adjustable pedals (if equipped) are also stored and recalled with the power driver seat positions.

The driver power seat is controlled by the driver seat module (DSM), if equipped. A new DSM must be configured after installation. For additional information, refer to MODULE CONFIGURATION . The driver seat also must be calibrated when a new DSM is installed or after the driver seat track is installed (if repaired or installed new). For additional information, refer to SEAT CALIBRATION .

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 must be calibrated to the driver seat track for correct memory seat operation. For additional information, refer to SEAT CALIBRATION . Once the DSM is calibrated to the seat track, it will only allow movement within the calibrated range.

The DSM communicates diagnostic trouble code (DTC) and other information using the MS-CAN communication bus. It should be noted for diagnostics that because 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 for additional information concerning MS-CAN bus communication.

Seat Calibration

The DSM is calibrated using a diagnostic tool. The calibration procedure automatically powers the driver power seat through its full range of motion and records the full stop positions by monitoring the motor position sensors. Once the full stop positions or range of the seat have been recorded, the DSM will only operate within the calibrated range. Any input attempting to drive the seat beyond the calibrated range will be ignored. This calibration is used for all seat control functions including manual switch control and memory recall positioning. During the seat calibration, the DSM may identify a function that is inoperative, such as a position sensor not changing. If the DSM identifies a concern that has a related diagnostic trouble code (DTC), the DSM will set the related DTC at the end of the validation procedure.

Programming Memory Seat Positions

1. A power driver seat position can be stored at any time. The driver must move the seat to the desired position using the driver seat control switch. The driver must then depress the memory SET switch which activates the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out), the driver must select a memory position. Memory 1 is selected by depressing memory switch 1. Memory 2 is selected by depressing memory switch 2.
2. If no memory switch input is received within the 5-second time limit, the operation is aborted and the memory SET switch LED is turned off. If one of the following inputs is received during the 5-second programming limit, the operation is aborted and the memory SET switch LED is turned off: Power driver seat control switch. Power outside rear view mirror switch. Memory SET switch. Power adjustable pedal switch.

Recalling a Stored Memory Seat Position

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.

Once the driver has stored the driver seat position, the driver can recall the setting by depressing the corresponding memory switch or by using a programmed remote entry transmitter.

The driver can recall the desired driver seat position by depressing one of the memory recall switches. Depressing memory switch 1 will initiate a recall of the power driver seat position stored in memory 1. Depressing memory switch 2 will initiate a recall of the power driver seat position stored in memory 2.

A remote entry transmitter can be used to recall previously set memory positions. The transmitter that has been assigned with personality 1 is capable of recalling memory position 1 only. Similarly, the personality 2 transmitter can recall only memory position 2.

Memory recall occurs when the UNLOCK switch is depressed on the remote entry transmitter. 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.

Memory positions that have not been programmed will not initiate any motion for the power driver seat, power memory rear view mirrors or adjustable pedals.

The driver and passenger heated seat modules (if equipped) share a common battery feed and ground source and have a separate ignition feed. The electronic automatic temperature control (EATC) module includes the heated seat control buttons and indicators. The heated seat system will function when the EATC module is ON or OFF. When a heated seat control button on the EATC module is pressed with the ignition switch in RUN or START, a momentary ground signal is sent to the heated seat module. Upon receiving a signal, the heated seat module will decrease one setting (the sequence is HI, LO, OFF, HI, etc.). When a heated seat is set to HI, both LED indicators above the heated seat control button will illuminate. When a heated seat is set to LO, only the left LED indicator will illuminate. When a heated seat is set to OFF, neither LED will be illuminated. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .

When the heated seat system is ON, the heated seat module then supplies power to the heating element circuit. The cushion element and backrest element are wired in series and powered by the same output. The heated seat module will remain on for 10 minutes or until the heated seat control button is pressed to cycle the heated seat module to the OFF state. If the ignition source is removed from the module, the heated seat module will enter an OFF state and will not return to ON until the heated seat control button is once again pressed with the ignition switch in RUN. The heated seat module is designed to heat the seat to 37.5°C (99.5°F) in LO setting and 42°C (107.6°F) in HI setting and maintain the temperature until switched off. This temperature is maintained by the heated seat module monitoring the temperature sensor, located in the seat cushion element, and adjusting the current flow to the heating elements.

Normal Operation

The driver seat control switch is powered by battery voltage to the driver seat control switch, circuit 566 (DG), and is supplied ground on driver circuit 1205 (BK). When pressed, the seat control switch supplies that voltage and ground to a power seat track motor or power recliner motor to move the seat or backrest. When pressed in the opposite direction, the seat control switch reverses the polarity to that same power seat track motor or power recliner motor, which moves the seat or backrest 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). There is an additional motor in the power recliner mechanism to move the seat backrest forward and rearward. If a new motor needs to be installed, it is necessary to install an entire power seat track or power recliner mechanism.

Possible Causes

An inoperative driver power seat can be caused by

1. a fuse.
2. wiring, terminals or connectors.
3. a faulty seat control switch.
4. a faulty power seat motor (power seat track).

The driver seat control switch is powered by battery voltage on driver circuit 566 (DG) and is supplied ground on circuit 1205 (BK). When pressed, the seat control switch supplies that voltage and ground to a power seat track motor or power recliner motor to move the seat or backrest. When pressed in the opposite direction, the seat control switch reverses the polarity to that same power seat track motor or power recliner motor, which moves the seat or backrest 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). There is an additional motor in the power recliner mechanism to move the seat backrest forward and rearward. If a new motor needs to be installed, it is necessary to install an entire power seat track or power recliner mechanism.

A driver power seat that does not move horizontally and/or vertically can be caused by

1. wiring, terminals or connectors.
2. a faulty seat control switch.
3. a faulty seat track motor (seat track).
4. a faulty power recliner mechanism.

The passenger seat control switch is powered by battery voltage on circuit 1462 (RD/WH) and is supplied ground on circuit 1205 (BK). 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 is a power seat track motor that moves the seat horizontally (FORWARD/REVERSE) and a motor in the power recliner mechanism that moves the seat backrest forward or rearward.

A power seat that does not move horizontally and/or vertically can be caused by

The driver seat control switch is powered by battery voltage on circuit 956 (OG/LG) and is supplied ground on circuit 1205 (BK). 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 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 circuit 566 (DG) and is supplied ground to DSM circuit 1203 (BK/LB).

Each motor, in the memory power seat track and power recliner mechanism contains a Hall-effect position sensor. The DSM supplies a signal feed circuit to each position sensor and a shared reference signal return circuit. Each position sensor sends a signal voltage 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. Refer to PRINCIPLES OF OPERATION or the owner's literature for additional information on programming the DSM for storing memory seat positions.

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 memory seat moves in all directions using the seat control switch, GO to PINPOINT TEST G .

An inoperative memory seat can be caused by

1. a fuse.
2. wiring, terminals or connectors.
3. a faulty seat control switch.
4. a faulty power seat track.
5. a faulty power recliner mechanism.
6. a faulty DSM.

The driver seat control switch is powered by battery voltage on circuit 956 (OG/LG) and is supplied ground on circuit 1205 (BK). 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 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 circuit 566 (DG) and is supplied ground to DSM circuit 1203 (BK/LB).

Each motor, in the memory power seat track and power recliner mechanism contains a Hall-effect position sensor. The DSM supplies a signal feed circuit to each position sensor and a shared reference signal return circuit. Each position sensor sends a signal voltage 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. Refer to the owner literature or Principles of Operation in this section. For additional information on programming the DSM for storing memory seat positions.

The following pinpoint test diagnoses a memory seat that does not operate correctly using the memory SET switch. If the memory seat does not move in all directions using the seat control switch, GO to PINPOINT TEST K .

A memory seat that does not operate correctly can be caused by

1. wiring, terminals or connectors.
2. a faulty memory SET switch.
3. a faulty remote entry transmitter.
4. a faulty memory power seat track.
5. a faulty recliner mechanism.
6. a faulty DSM.

The driver and passenger heated seat modules share a common battery and ignition feed and have a separate ground source. The electronic automatic temperature control (EATC) module includes the heated seat control buttons and indicators. The heated seat system will function when the EATC module is ON or OFF. When a heated seat control button on the EATC module is pressed with the ignition switch in RUN or START, a momentary ground signal is sent to the heated seat module. Upon receiving a signal, the heated seat module will decrease one setting (the sequence is HI, LO, OFF, HI, etc.). When the heated seat system is ON, the heated seat module then supplies power to the heating element circuit. The cushion element and backrest element are wired in series and powered by the same output. The heated seat module will remain on for 10 minutes or until the heated seat control button is pressed to cycle the heated seat module to the OFF state. If the ignition source is removed from the module, the heated seat module will enter an OFF state and will not return to ON until the heated seat control button is once again pressed with the ignition switch in RUN.

An inoperative heated seat can be caused by

1. open fuse.
2. wiring, terminals or connectors.
3. a faulty heated seat element.
4. a faulty heated seat module.
5. a faulty EATC module.

The driver and passenger heated seat modules share a common battery and ignition feed and have a separate ground source. The electronic automatic temperature control (EATC) module includes the heated seat control buttons and indicators. The heated seat system will function when the EATC module is ON or OFF. When a heated seat control button on the EATC module is pressed with the ignition switch in RUN or START, a momentary ground signal is sent to the heated seat module. Upon receiving a signal, the heated seat module will decrease one setting (the sequence is HI, LO, OFF, HI, etc.). When the heated seat system is ON, the heated seat module then supplies power to the heating element circuit. The cushion element and backrest element are wired in series and powered by the same output. The heated seat module will remain on for 10 minutes or until the heated seat control button is pressed to cycle the heated seat module to the OFF state. If the ignition source is removed from the module, the heated seat module will enter an OFF state and will not return to ON until the heated seat control button is once again pressed with the ignition switch in RUN.

An inoperative heated seat can be caused by

1. open fuse.
2. wiring, terminals or connectors.
3. a faulty heated seat element.
4. a faulty heated seat module.
5. a faulty EATC module.
