The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

Condition/Concern:

False DTC U2105 In EPS Module.

Recommendation/Instructions:

A U2105 code may be stored in the Electric Power Steering (EPS) module. The code will NOT cause the SVS/MIL lamp to illuminate. If it is in HISTORY only, simply clear the code and check that it does not return after a couple of ignition cycles. If the code is CURRENT, it indicates that the EPS module cannot communicate with the ECM properly, and the source of the communication fault should be investigated. This code may set at the assembly plant or during service procedures where normal mode communications may be interrupted.

.

Please follow this diagnosis 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. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance.
