Cadillac SRX AWD malfunction with 'service rear axle' message on Cadillac SRX

Some Cadillac SRX AWD owners report experiencing the "service rear axle" message on the Driver Information Center (DIC), which typically indicates a potential issue with the rear axle system. This message may appear intermittently, particularly in models from 2010 to 2012. Technicians diagnosing this issue have identified error codes, such as C0407 sym64, stored in the rear differential clutch control module (CCM). In certain cases, a shorted differential clutch pump has been found to be the cause, resulting in the need to replace the rear differential clutch control module under warranty. Additionally, to mitigate misdiagnosis, updated diagnostic procedures in Service Information aim to prevent unnecessary replacements of the Rear Differential Control Module (RDCM) or Module Kit. Owners encountering this message are advised to consult a qualified mechanic or dealership for effective diagnosis and resolution of the underlying issue.
