1. Carry out the Battery Monitoring System (BMS) Reset using the scan tool after the battery is connected, if the battery has been replaced. If the BMS Reset is not carried out, it takes approximately 8 hours for the Body Control Module (BCM) to learn the new battery state of charge. During this 8 hour period, the vehicle must be undisturbed, with no doors opened or keyless entry button presses. If the vehicle is used before the BCM is allowed to learn the new battery state of charge, engine off load shedding can still occur and a message may be displayed.
