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

Condition/Concern:


The DIC may display "Service Steering" in combination with an increase in steering effort and standard diagnostics may lead to steering gear replacement. As of 03/30/2012 Electronic Power Steering P/N 22848599 has been placed on restriction through PQC. This part restriction will allow Engineering to evaluate the fault while the steering gear is in the vehicle and prior to any repairs.

Recommendation/Instructions:

Important: Do not perform a Clear DTCs function.


Retrieve any stored DTC information from the Electronic Power Steering module. If any of the following DTCs are set (history or current) in the EPS module or you are unable to diagnose the cause DO NOT CLEAR DTC(s), STOP FURTHER SERVICE ACTIVITY, complete the questionnaire below and contact PQC for further action.

•

DTC C0545





•

DTC C056D

For all other concerns where the above DTCs are not set, follow the published service procedures to complete the repair. Should the repair require steering gear replacement, contact PQC to review the diagnosis and order the part.

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.




GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
