Description and Operation

For a detailed description of the multifunction electronic control modules, refer to the relevant Description and Operation
sections in the workshop manual. REFER to: (419-10 Multifunction Electronic Modules)

Module Controlled Functions (Description and Operation), Module Controlled Functions (Description and Operation), Module Controlled Functions (Description and Operation).
Inspection and Verification


CAUTION: Diagnosis 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 tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.



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, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


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).


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.


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


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


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.

HEATED SEATS - OPERATION

Heated Front Seats System Operation

The TSD receives a fused power supply from the RJB. One of the 3 seat heat temperature selections made by the driver or passenger using the TSD soft keys are passed from the TSD on the MOST ring to the Information and Entertainment module.
The information and entertainment module processes the information and transmits the request on the medium speed CAN bus to the ATC module.
The cushion heaters have a thermal sensor which supplies a feed back signal back to the CJB. The squab heater elements do not have a thermal sensor and are maintained at the same temperature as the seat cushion elements.

The ATC module reacts to the driver request information received from the information and entertainment module and requests the CJB to activate the seat heaters. The CJB measures the returned temperature signals from the thermal sensors and relays the temperature signals back to the ATC module. The ATC module then uses the measured seat element temperatures to provide closed-loop control of the heater elements to maintain the temperature at one the 3 heat ranges selected.


NOTE: To prevent excessive battery discharge, the heated front seats will only operate when the engine is running.

Heated and Cooled Front Seats

The TSD receives a fused power supply from the RJB. Selections made by the driver using the TSD soft keys are passed from the TSD on the MOST ring to the Information and Entertainment module. The information and entertainment module processes
the information and transmits the request on the medium speed CAN bus to the front seat climate control module. The front seat climate control module is located beneath the RH (right-hand) front seat, on the floor cross member.

The front seat climate control module receives its power supplies from the CJB. Heating and cooling requests are generated using the soft buttons on the TSD. These requests are transmitted to the information and entertainment module over the
MOST ring. The Information and Entertainment module forwards these requests to the front seat climate control module over
the medium speed CAN bus.
The front seat climate control module supplies power to the two climate modules in each seat. The temperature sensor in each
climate module is monitored by the front seat climate control module which uses the temperature information to control the
Peltier cells accordingly and also the blower fans to distribute the heated or cooled air.


NOTE: To prevent excessive battery discharge, the heated and cooled front seats will only operate when the engine is
running.
Electric Driver's Seat Adjustment - Non-Memory Seats

The CJB supplies 3 power supplies to the driver's seat switchpack. The fused supplies provide power for the seat height and squab recline, the seat slide and seat tilt and the lumbar adjustment respectively. The CJB only provides the power to the driver's seat switch pack when the ignition is on (power mode 6).

For the seat movement motors, when the applicable switch is operated, the power is supplied to the applicable side of the
motor and the ground path is completed to operate the motor in the required direction. To move the motor in the opposite
direction the polarity is reversed.

For the lumbar adjustment, when the switch is operated in the inflate position, power is supplied to the pump motor to inflate
the lumbar support. When the switch is operated in the opposite direction, the power energizes a solenoid which in turn opens
a valve to deflate the lumbar support.
Electric Passenger Seat Adjustment ( 8, 10 and 12 way)

The CJB supplies 3 power supplies to the passenger seat switchpack. The fused supplies provide power for the seat height and squab recline, the seat slide and seat tilt and the head restraint and lumbar adjustment respectively. The CJB only provides the power to the passenger seat switch pack when the ignition is on (power mode 6).

For the seat movement and head restraint motors, when the applicable switch is operated, the power is supplied to the
applicable side of the motor and the ground path is completed to operate the motor in the required direction. To move the

Principles of Operation Published: 12-Jun-2013

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.

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


The DTC index containing an actions list is for guidance only any reference to “check and install new blower unit” should
only be carried out following 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


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
