Issue Description
Some customers may experience a dead battery when the vehicle is parked, with an abnormally high current draw traced to the F12 BCM LOGIC fuse or BCM fuse.
Cause and Recommendation
One possible cause is a short to ground on circuit 1732, which can be detected by measuring resistance to ground using an ohm meter. Another possible cause is the Glove Box Light staying on intermittently.
Recommendations:
- Measure resistance to ground on circuit 1732 with the interior lights off.
- Inspect the Glove Box switch for proper depression.
