| U1000:00 | Solid State Drive Protection Activated-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 Body Control Module B (BCM-B) cannot enable the output until the cause of the short is corrected. ADDRESS all other DTCs first. After the cause of the concern is corrected, CLEAR the 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 BCM-B BCM-B can withstand. The cause of the excessive current draw MUST be corrected before a new BCM-B is installed. ADDRESS all other DTCs first. After the cause of the concern is corrected, INSTALL a new BCM-B. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation. |
| All other DTCs | - | REFER to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULES . |
