Please discard PIP4670H. 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 module from one vehicle to another. Recommendations / 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 security code protocol (environment) starting with the 2010 MY GDS applications. 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. Additional SI Keywords B389A B3902 © 2022 General Motors. All Rights Reserved.
