Diagnostic Aids
- If replacing the Rear Differential Clutch Control Module, but not the assembly, the module needs to be configured with the rear differential clutch service calibration values. The rear differential clutch calibration values will need to be retrieved from the old Rear Differential Clutch Control Module during Prepare the Control Module for Removal process and programmed into the new Rear Differential Clutch Control Module using SPS.
- If replacing only the Rear Differential Clutch Control Module, run Prepare the Control Module for Removal.
- If replacing the rear differential clutch assembly and keeping the old RDCM, the RDCM will only need to be configured with the number stamped on the housing using a scan tool.
- If original Rear Differential Clutch Control Module is not communicating, skip the Prepare the Control Module for Removal step.
