Diagnosis and Testing

Principle of Operation Published: 18-Apr-2013

For a detailed description of the seats and seat operation, refer to the relevant Description and Operation section in the
workshop manual. REFER to: (501-10 Seating)

Seats (Description and Operation), Seats (Description and Operation), Seats (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.


NOTE: Prior to carrying out any diagnosis, ensure the vehicle battery is in a good serviceable condition, refer to the
battery care manual.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection
Mechanical Electrical
Security, condition and correct installation of seat components and fixings
Fuses
Harnesses for damage/corrosion
Electrical connectors
Damaged/corroded pins
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 concern and refer to the Symptom Chart, alternatively, check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

5. Check DDW for open campaigns. Refer to the corresponding bulletins and SSM's which may be valid for the specific
customer complaint and carry out the recommendations as needed.

Refer to the electrical circuit diagrams and check seat
switch pack to memory switch pack circuits for short,

Symptom Possible Cause Action open circuit Seat movement and memory recall works
correctly however seat lumbar is not
working correctly
NOTE: Seat module
does not control the seat
lumbar function

Seat movement
switch to lumbar
circuits - short,
open circuit Refer to the electrical circuit diagrams and check seat
movement switch to lumbar circuits for short, open
circuit Seat movement from switch pack occurs
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
on affected axis is
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
lumbar). This behaviour will occur on ALL
seat axis (slide, height, squab, tilt
headrest and cushion) when requested.
MS CAN communication not possible
MS CAN fault Carry out CAN network integrity test using manufacturer
approved diagnostic system 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
lumbar). This behaviour will occur on ALL
seat axis (slide, height, squab, tilt
headrest and cushion) when requested.
MS CAN communication not possible
Seat module is
disconnected from
the CAN Bus Check for Instrument Cluster DTC U020800 'Lost
Communication With Seat Module'. If this DTC is
present, refer to the electrical circuit diagrams and check
seat module power and ground supplies for short, open
circuit. Carry out CAN network integrity tests using the
manufacturer approved diagnostic system 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
lumbar). This behaviour will occur on ALL
seat axis (slide, height, squab, tilt
headrest and cushion) when requested.

Symptom Possible Cause Action
NOTE: Electric passenger seat can
always be activated – there is no
passenger seat module installed to this
vehicle

Seat module does not go to sleep. Seat
movement is always active from driver
seat switch pack
Seat module is in
manufacturing
mode
NOTE: A new module is NOT required to be
installed, only the module replacement routine needs to
be performed. This will set the PID required to disable
manufacturing mode

Seat module needs to be configured for customer mode.
Check for DTC U1A4C68 'Build/End of Line mode Active'.
If this DTC is present then configure for customer mode
by running 'New Seat Module Replacement' application
for the affected seat using the manufacturer approved diagnostic system Front seat fore/aft movement not
functioning
Carry out the
pinpoint test
associated to this
Symptom GO to Pinpoint Test A. Front seat excessive fore/aft free play

Carry out the
pinpoint test
associated to this
Symptom GO to Pinpoint Test D. Front seat height, tilt and/or extension
movement noisy
Carry out the
pinpoint test
associated to this
Symptom GO to Pinpoint Test E. 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.
