Hi,

I attached the ground schematic below for the BCM. Its ground is G302 located on the left side bottom of the B pillar. I can tell you the ground supply has a few different splices in it that can fail, so once you locate the ground, confirm there is continuity in the wire from end to end.

Take a look below. If you need anything further regarding the BCM wiring schematics, let me know. Also, pic 2 shows the G302 location.

Take care,

Joe
