- 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.NOTE:

- If replacing only the Rear Differential Clutch Control Module, before removal record the Module ID Information screen values then run Prepare the Control Module for Removal.
- If renewing the complete Rear Differential, before installation record the left and right clutch ID values.
- 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.
NOTE:
Number will be located on the top of the differential carrier assembly by the right rear mount
