Please discard PIP4670C. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern A technician may comment of a no start or another concern after swapping an ECM or other modules from one vehicle to another. Recommendation/Instructions The Global Architecture electrical system associated with these vehicles does not allow controller swaps between vehicles. Swapping ECMs or other modules (including Radio, BCM, EBCM, SDM, TCM, ECC (HVAC), EPS, HPCM, & IPC) between two vehicles with the Global Architecture electrical system will result in damaging both controllers (A NO START CONDITION WILL OCCUR ON BOTH VEHICLES IF THESE MODULES ARE SWAPPED) due to the new vehicle 1 security code protocol (environment) starting with the 2010 MY GDS applications. ADDITIONAL SI KEYWORDS: B389A B3902 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. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION 2
