| 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 BCMB 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. |
| 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 BCMB can withstand.

After the cause of the concern is corrected, INSTALL a new BCMB. |
