Diagnostic Aids

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.

Because of how the key information is stored in the BCM and the ECM, it may be necessary to begin immobilizer programming with a new vehicle key if DTC B2955 sets immediately after attempting to program a new BCM. This will allow the key information to be transferred between the BCM and the ECM. DTC P0633 may also be set in the ECM and a "No Communication with driver ID Device" error may be displayed during the BCM programming. After programming has begun with the new vehicle key, the existing vehicle keys may then be programmed.
