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

in delayed inch mode (seat axis moves
short distance when switch pressed for
longer than 2 seconds and then stops). This behaviour could occur on any seat
axis (slide, height, squab, tilt, headrest
or cushion) when requested
Motor Hall sensor

not connected or
not receiving
expected signals Check for DTCs, B1B8731, B1B9131, B1B8931, B1B9331,
B106331, B106431. If present then check Hall sensor
feedback circuits between seat motor and seat module
and also check Hall sensor ground circuits for affected
axis. These DTCs are only logged if the axis is
attempted to be moved in both directions. When hall
sensor connection issue fixed press switch on affected
axis for longer than 2 seconds. By keeping the switch
pressed the axis movement should now operate for the
duration of switch-press. Re-calibrate affected seat Seat movement from switch pack occurs
in inch mode. When seat axis movement
is requested from the seat switch pack
the requested seat axis moves a short
distance then stops (does not include

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.
