workshop manual. REFER to: Rear Drive Axle and Differential (205-02 Rear Drive Axle/Differential, 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.
Mechanical Electrical
Fixings that secure Rear Differential Control Module (Heat path
for Module Heatsink)
Fuses/Relays
Damaged, Loose or Corroded Connector(s)
Damage to Wiring Loom/Incorrect Location,
Stretched or Taught
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 the system for any logged Diagnostic Trouble Codes (DTCs) and refer to the
DTC index.
DTC Index
For a list of diagnostic trouble codes that could be logged on this vehicle, please refer to Section 100-00. REFER to: Diagnostic Trouble Code (DTC) Index - DTC: Rear Differential Control Module (RDCM) (100-00 General Information, Description and Operation).
