BCM DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B145C:11 | Ambient Lighting Power Supply Output: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the ambient light module conditioned power supply output circuit. |
| B145C:15 | Ambient Lighting Power Supply Output: 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 ambient light module conditioned power supply output circuit. |
| B1465:00 | Ambient Lighting Bus 1: No Sub Type Information | A continuous memory DTC that sets when the BCM detects a fault on an ambient lighting LIN circuit. |
| B1467:00 | Ambient Lighting Bus 3: No Sub Type Information | A continuous memory DTC that sets when the BCM detects a fault on an ambient lighting LIN 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. |
