WARNINGWARNING: Prior to removal of the front seats and before disconnecting the front seat wiring harness electrical connectors (which includes the side air bag module electrical connectors), the battery ground cable should be disconnected and a period of at least 1 minute allowed to elapse. The same amount of care should be taken when handling and storing the front seats, as would be taken when handling and storing air bag modules.

Both variants of the front seats are fitted with a manually adjustable folding armrest on the inboard side of the seat. The memory recall functions are also available on higher specification vehicles.

The driver and passenger front seats, although almost identical, have some unique components. The front driver seat has a seat position sensor and the front passenger seat, for North American Specification (NAS) vehicles, has a seat occupant classification system, where as Rest Of the World (ROW) vehicles, except Australia, has a seat occupancy detection system. In both instances the components form an integral part of the Supplemental Restraint System (SRS). For additional information, refer to: Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) - Description & Operation .

The rear bench seats are designed to fold forward to increase the rear load space. a 60:40 split gives the owner increased flexibility when loading the vehicle with large objects. All rear seats are equipped with 3-point seat belts and adjustable head restraints. High line specification vehicles are also fitted with seat cushion heaters in both outboard seats.

ItemPart Description
1Electric head restraint motor

Manual adjustment of the seat position can be carried out at any time, having priority over memory recall. For more information regarding seat operation, refer to the owner's handbook.

FRONT SEAT CONTROL COMPONENTS

Seat position is monitored by the seat module using seat track position Hall sensors incorporated into the motors. Seat memory is standard on the driver's seat. Each seat memory can be configured for 3 personality positions, which are set using the seat memory switch and stored in the driver seat module.

The switches for electrically adjusting the seats are located in the seat pack on the seat valance. The seat module is integral to the switch pack and controls the movement of the seat via hard-wired connections to the motors.

SEAT MOTORS

The seat motors are permanent magnet motors. Two pins within the seat switch pack control the motors. Both pins are connected to ground. Operating a switch in one direction will apply voltage to that pin while the other pin remains connected to ground. Operating the switch in the opposite direction reverses power and ground to the motor allowing the motor to run in the opposite direction.

The seats can be manually adjusted at any time. Positioning is interrupted if manual adjustment is required during automatic adjustment (memory recall). The manual adjustment is not effective before the switch is operated again.

Due to the sequential activation of the drive motors, the switch requests are prioritized in the following order

  1. Forward/rearward adjustment
  2. Backrest
  3. Height
  4. Angle
  5. Backrest head
  6. Steering column angle
  7. Steering column forward/rearward adjustment.

Scheme 5: HEATED SEATS
ItemPart Description
1Seat back heater
2Seat cushion heater
3Seat back climate control motor (optional on high line variants)
4Seat cushion climate control motor (optional on high line variants)

The seat heater elements are located in the seat cushion and backrest. The cushion and backrest heater elements are wired in series. The cushion heater element has an input feed from the temperature control unit and an output to the backrest heater element, which outputs to ground.

The seat heaters are thermostatically controlled and will operate intermittently to maintain a predetermined temperature. The indicators in the switches will remain illuminated until the heaters are either manually turned off, or the starter switch is turned off.

Feedback of the seat temperature is via a Negative Temperature Coefficient (NTC) sensor within the seat cushion. The resistance of this sensor changes with the temperature of the seat cushion allowing the Automatic Temperature Control (ATC) module to raise or lower the voltage to the seat heater elements to raise or lower their temperature.

An ignition feed is supplied to each sensor via the relevant seat heater switch.

CAUTIONThe seat heaters consume considerable power from the battery. For this reason, they should only be operated while the engine is running.

Operation of the heated seats is controlled by the ATC module. Two push-button switches are mounted in the ATC module panel. Each switch has 2 integral Light Emitting Diodes (LED) to display the level of heating selected. For additional information, refer to: Control Components (Description and Operation).

Scheme 6

Scheme 6: CLIMATIC SEATS
ItemPart Description
ALo-line and hi-line variants with heated front seats
BHi-line variant with seat climatic control option
1Front seat heater/climatic switches

High specification vehicles are fitted with climatic seats, which are able to deliver heating and cooling to the front seat occupants. Vehicles fitted with climatic seats feature 2 additional rotary controllers mounted in the instrument panel switch pack, adjacent to the clock. The rotary controllers are used to select cooling. Three levels of cooling and heating are available, dependent on the degree of switch rotation. The center of the switch is pressed once to ventilate both the seat back and cushion (both indicators on the switch will illuminate). A second press of the switch will ventilate the seat back rest only (the cushion indicator will extinguish).

Note. If climatic seats are fitted, heated seat switches are not featured on the ATC module control panel.

Note. The ATC module does not control any aspect of climatic seat operation.

The controlling software for the climatic seats is contained within a control module mounted below the driver's seat. When a temperature selection is made through either of the rotary controllers, the instrument panel switch pack provides a Pulse Width Modulation (PWM) signal to the control module. The control module interprets the PWM signal as a temperature value and attempts to heat or cool the seat accordingly.

Both climatic front seats contain two Peltier cells; one in the cushion, one in the backrest. The Peltier cells are able to deliver heating and cooling based on a voltage provided by the control module. Each seat also contains a fan, which blows air over the Peltier cells to distribute heating or cooling throughout the seat. The Peltier effect occurs when an electrical current is passed through a junction formed by two dissimilar conductors, creating a heat pump. A heat pump absorbs heat from one side of the system, causing it to cool, and then transfers the heat to the other side, causing it to warm. The cell is capable of cooling the incoming air by approximately 8°C (12.4°F), which means that temperature output will depend on the ambient temperature inside the vehicle.

The climatic seat control module monitors seat heating through a NTC temperature sensor. The temperature sensor is only used to monitor seat heating. Seat cooling is open loop, with no temperature signal provided back to the control module. When a temperature selection is made through either of the rotary controllers, the instrument panel switch pack provides a PWM signal to the climatic seat control module, which interprets the PWM signal as a temperature value and attempts to heat or cool the seat accordingly.

Although the switch LED's will illuminate if a selection is made when the ignition is switched on, the Peltier cells will not operate until the engine is running. After the ignition is switched off, the climatic seat control module will retain the current temperature settings for approximately 15 minutes. After this period, the seats will be set to 'off' when the ignition is switched back on.

For additional information, refer to: Control Components (Description and Operation).

Scheme 7: REAR SEATS
ItemPart Description
1LH rear seat heater switch
2RH rear seat heater switch

The rear seat heater elements are located in the outboard seat cushion and backrest. The cushion and backrest heater elements are wired in series. The cushion heater element has an input feed from the heater switch and an output to the backrest heater element, which outputs to ground.

The seat heaters are thermostatically controlled and will operate intermittently to maintain a predetermined temperature. The indicators in the switches will remain illuminated until the heaters are either manually turned off, or the starter switch is turned off.

Feedback of the seat temperature is via a NTC sensor within the seat cushion. The resistance of this sensor changes with the temperature of the seat cushion allowing the rear seat heater switch pack to raise or lower the voltage to the seat heater elements to raise or lower their temperature.

An ignition feed is supplied to each sensor via the relevant seat heater switch.

CAUTIONThe seat heaters consume considerable power from the battery. For this reason, they should only be operated while the engine is running.

Operation of the heated seats is controlled by the ATC module. Two push-button switches are mounted at the rear of the floor console. Each switch has 2 integral Light Emitting Diodes (LED) to display the level of heating selected. For additional information, refer to: Control Components (Description and Operation).

Scheme 8

Scheme 8: LUMBAR PUMP
ItemPart Description
1Bladder
2Solenoid
3Pump

The lumbar pump inflates a bladder in the backrest, which provides extra support for the seat occupant. With no load on the seat it takes approximately 10 seconds to completely inflate the bladder. With a load of 25 kg (55 lb) it takes approximately 15 seconds to inflate the bladder. A pressure cut off switch in the system will operate at 0.12 to 1.93 bar (1.8 to 28 lbf.in 2 ). The lumbar bladder can be replaced independently of the pump. The components are not serviceable.

MEMORY CONTROL MODULE

The memory control module, located within the driver switch pack, relies upon a number of inputs to control various outputs. As with all electronic control modules, the unit needs information regarding the current operating conditions of the engine and other related systems before it can make calculations, which determine the appropriate outputs.

The memory control module can store up to 3 different driver seating, mirror and steering column positions for each key.

All memory values are stored in the non-volatile memory, EEPROM. The current motor positions, which are monitored by the control modules integral Hall sensors, are stored in the EEPROM. If a loss of power occurs, upon power reconnection the current motor position are recalled from the memory and adopted as the current positions. This will allow the relative memory positions to be retained without any need to re-calibrate. The memory control module checks the integrity of all data stored in the EEPROM each time it exit's stand-by mode. In the event that the data is corrupt, the control module adopts the default values for all of the programming options. All memory positions are deemed as invalid and the software will perform as if there are no memory positions stored. Following the procedure for storing a memory position again will reset the relevant memory and allow full functionality.

MEMORY FUNCTION

Controlled by the memory module, the memory function stores and recalls the position of the driver's seat, the steering column and the exterior mirrors.

The memory recall functions are

  1. Forward/backward adjustment
  2. Seat height
  3. Seat angle
  4. Backrest angle
  5. External mirror adjustment
  6. Steering column adjustment

The seat, steering column, and exterior mirrors will move to the stored position whenever the relevant memory-recall button in pressed.

For more information regarding the operation of the memory function, refer to the owner's handbook.

Note. Seat, steering column and exterior mirror movement will be halted if any seat adjustment switch (including memory buttons) or the steering column adjustment switch is moved or pressed. To re-start movement of these, the relevant seat memory button will need to be pressed again.

EASY ENTRY/EXIT

The 'Easy Entry/Exit' mode provides automatic movement of the steering column to allow easier entry to or exit from the vehicle.

Note. If the adjustment switch is moved during entry/exit operation, steering column movement will stop.

When the key is inserted in the ignition the steering column will return to their previous positions. If, however, the memorized driver position has been changed (using the seat memory switches or another key transmitter), the steering wheel and seat will move to the new position.

When the ignition key is removed, the steering column will move to the uppermost rake.

STALL DETECTION

Seat, steering column and mirror motors are deemed to have stalled if there is no change in the inputs that are received from the corresponding feedback sensors while that axis is being driven.

If a stall condition is detected then the drive to that axis is cancelled for the remainder of that memory operation (memory recall) or until the switch is re-selected (manual movement).

If the motor movement has stopped due to loss of sensor feedback, either, stall or sensor failure, then that axis may be activated again, to move past the stall position, by re-selecting the appropriate switch. This allows control of the motor to be maintained if sensor feedback is lost.

Upon re-selection of movement, if sensor pulses are detected then the motor will continue to be driven until the switch is released or another stall condition is detected. If sensor feedback is not detected then the motor is only driven for 0.5 second and then stops until the switch is released and then pressed again, when a further 0.5 second of activation is permitted, and so on.

For all seat motor and steering column manual movements, whenever a motor is driven and a stall occurs, the memory control module records the position at which the stall occurred. If movement occurs beyond a stall position, then that position is erased from the control modules memory. This will always allow movement past a previously recorded stall position once movement has been registered beyond that position. This is the case for both manual and memory movement.

PRINCIPLE OF OPERATION

For a detailed description of the seating systems and operation, refer to the relevant Description and Operation instructions of the workshop information. Refer to Seats . .

INSPECTION AND VERIFICATION

CAUTIONDiagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.

Note. Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

Note. If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures Information or determine if any prior approval program is in operation, prior to the installation of a new module.

Note. Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information read by the manufacturer approved diagnostic system).

Note. When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.

Note. Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

Note. If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.

  1. Verify the customer concern.

PRINCIPLES OF OPERATION

Heated seats incorporate heater elements in the cushion and the backrest of the seat. Each cushion heater element has a thermal sensor, which supplies a feedback temperature signal to the related seat heater module. The backrest heater elements do not have a thermal sensor, and are regulated at the same temperature as the cushion heater elements.

For a detailed description of the seat heater mat, refer to the relevant Description and Operation instructions in the information. Refer to Seats . .

  1. Verify the customer concern.
  2. Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION Mechanical Electrical Seat heater switches condition and installation Fuses Harnesses and connectors Seat heater module Seat heater switches Seat heater mat
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart.

Note. If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the warranty policy and procedures information (instructions B1.2), or determine if any prior approval program is in operation, prior to the installation of a new module/component.

Note. Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information read by the manufacturer approved diagnostic system).

Note. When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.

Note. Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

Note. Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

Note. If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.

CAUTIONDiagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle

Note. If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures information or determine if any prior approval program is in operation, prior to the installation of a new module

Note. Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information read by the manufacturer approved diagnostic system)

Note. When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account

Note. Inspect connectors for signs of water ingress, and pins for damage and/or corrosion

Note. Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

Note. If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals

Note. The climate system functions in a manner that means any detected error state either intermittent or permanent will shut down the complete seat climate system until the next ignition cycle, this does not mean that both climate units within the one seat have failed. This shut down is design intent to protect the system to ensure that the fault detected does not damage the units, it is possible that both units are functioning correctly and that the fault lies elsewhere within the system. The following process can be carried out without removing either the seats or the climate units from the vehicle and should correctly identify any failed units, this should ensure that only failed units are changed under warranty. Any units exhibiting the correct reading as per process below, should NOT be changed under warranty. If all units have a correct reading then re-confirm customer symptom, if customer symptom is still present then carry out further system checks

Note. The DTC Index containing an actions list is for guidance only and any reference to "Install a new heater and blower assembly if necessary" should only be carried out following unit failure confirmation using the Pin Out Diagnostics and/or the Over Temperature and Fluid Air Leak Diagnostics contained below, the recording of a DTC does NOT signify a permanently failed unit
