Condition | Possible Sources | Actions |
|---|---|---|
The reversing lamp is inoperative - Except China | Refer to the Pinpoint Test | GO to Pinpoint Test A |
Both reversing lamps are inoperative - China Only | Refer to the Pinpoint Test | GO to Pinpoint Test A |
One reversing lamps are inoperative - China Only | Refer to the Pinpoint Test | VERIFY the reversing lamp bulb is OK. If OK, INSTALL a new reversing lamp assembly. REFER to: Reversing Lamp (417-01 Exterior Lighting, Removal and Installation). If not OK, INSTALL a new reversing lamp bulb. |
The reversing lamp(s) are on continuously | Refer to the Pinpoint Test | GO to Pinpoint Test B |

DTC Fault Trigger Conditions
Description | Fault Trigger Conditions | |||
|---|---|---|---|---|
DTC | ||||
B1277:11 | Reverse Lamp: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the reversing lamps output circuit. | ||
B1277:15 Reverse Lamp: Circuit Short To Battery or Open | A continuous memory and on-demand DTC that sets when the BCM detects an open or short to voltage from the reversing lamps output circuit. | |||
U1000:00 Solid State Driver Protection Active -Driver Disabled: No Sub Type Information | This DTC sets when the BCM has temporarily shut down the output driver. 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, the Diagnostic Trouble Codes (DTCs) have been cleared and a successful self-test is run. | |||
U3000:49 Control Module: Internal Electronic Failure | This DTC sets when the BCM has permanently shut down the output driver. 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. CORRECT the cause of the excessive current draw before installing a new BCM. | |||
