| DTC | Description | Action |
|---|---|---|
| B1277:11 | Reverse Lamp: Circuit Short To Ground | GO to Pinpoint Test A |
| B1277:15 | Reverse Lamp: Circuit Short To Battery or Open | If the reversing lamps are is inoperative, GO to Pinpoint Test A If the reversing lamps are always on, GO to Pinpoint Test C |
| U1000:00 | Solid State Driver Protection Active -Driver Disabled: No Sub Type Information | The module has temporarily disabled an output because an excessive current draw exists (such as a short to ground). The BCM cannot enable the output until the cause of the short is corrected. ADDRESS all other Diagnostic Trouble Codes (DTCs) first. After the cause of the concern is corrected, CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. For additional information on BCM Field Effect Transistor (FET) protection, REFER to: Body Control Module (BCM) - System Operation and Component Description . |
| U3000:49 | Control Module: Internal Electronic Failure | The module has permanently disabled an output because an excessive current draw fault (such as a short to ground) has exceeded the limits that the BCM can withstand. The cause of the excessive current draw MUST be corrected before a new BCM is installed. Refer to BCM Guided Routine .
