DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1D08:11 | Left Trailer Direction Indicator: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the TRM detects a short to ground from the LH trailer stoplamp/turn signal output circuit. |
| B1D08:12 | Left Trailer Direction Indicator: Circuit Short To Battery | A continuous memory and on-demand DTC that sets when the TRM detects a short to voltage from the LH trailer stoplamp/turn signal output circuit. |
| B1D09:11 | Right Trailer Direction Indicator: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the TRM detects a short to ground from the RH trailer stoplamp/turn signal output circuit. |
| B1D09:12 | Right Trailer Direction Indicator: Circuit Short To Battery | A continuous memory and on-demand DTC that sets when the TRM detects a short to voltage from the RH trailer stoplamp/turn signal output circuit. |
| U1000:00 | Solid State Driver Protection Activated - Driver Disabled: No Sub Type Information | A continuous DTC that sets when the TRM has temporarily shut down the output driver. The module has temporarily disabled a trailer stop/turn lamp output because an excessive current draw exists (such as a short to ground). The TRM cannot enable the trailer stop/turn lamp 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 | A continuous DTC that sets when the TRM has permanently shut down the output driver. The module has permanently disabled a trailer stop/turn lamp output because an excessive current draw fault (such as a short to ground) has exceeded the limits that the TRM can withstand. The cause of the excessive current draw MUST be corrected before a new TRM is installed. |
