The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

A "Service Stability Message" appears on the Drivers Information Center as a result of a DTC C0561 set in the Electronic Brake Control Module (EBCM). The EBCM receives messages from other modules over GMLAN which are needed to perform ABS, VSES, and/or TCS functions.

Recommendation/Instructions:

Don't replace the EBCM to resolve this concern. The PCM or BCM will typically set a DTC when the EBCM sets this DTC. Address DTCs in all modules before trying to address DTC C0561. There have been some cases in the field where the diagnostic code was a type "B" code that would not set a "check engine lamp" but would set a DTC C0561 in the EBCM. Please inspect the freeze frame and failure records in the PCM for anything that may cause a powertrain related code.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
