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.
