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).

Parking Brake Calibration

The parking brake system must be calibrated whenever the battery has been disconnected or has been in a state of discharge,
or repairs have been carried out to the rear service or parking brake system.


NOTE: If new rear brake pads have been installed, pressure must be applied to the brake pedal a minimum of five times
prior to calibration of the parking brake system.
To calibrate the parking brake system:
1. Place gear selector lever in 'P' Park position.

2. Release parking brake cable tension to service position.
REFER to: Parking Brake Cable Tension Release (206-05 Parking Brake and Actuation, General Procedures).
3. Set the ignition status to 'ON'.
4. Apply and hold the footbrake then pull up the parking brake switch.

5. To release the parking brake, apply and hold the footbrake then release and press down the parking brake switch.
