BCMB DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B132B:11 | Left Stop/Turn Lamp: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCMB detects a short to ground from the LH rear stoplamp voltage supply circuit. |
| B132B:15 | Left Stop/Turn Lamp: Circuit Short To Battery or Open | A continuous memory and on-demand DTC that sets when the BCMB detects an open or short to voltage from the LH rear stoplamp voltage supply circuit. |
| B132C:11 | Right Stop/Turn Lamp: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCMB detects a short to ground from the right RH stoplamp voltage supply circuit. |
| B132C:15 | Right Stop/Turn Lamp: Circuit Short To Battery or Open | A continuous memory and on-demand DTC that sets when the BCMB detects an open or short to voltage from the right RH stoplamp voltage supply circuit. |
| U1000:00 | Solid State Driver Protection Active -Driver Disabled: No Sub Type Information | This DTC sets when the BCMB 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 BCMB 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 BCMB 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 BCMB can withstand. CORRECT the cause of the excessive current draw before installing a new BCMB. |
