| U1000:00 | Solid State Driver Protection Activated - Driver Disabled: No Sub Type Information | The Generic Function Module (GFM) has temporarily disabled an output because an excessive current draw exists (such as a short to ground). The Generic Function Module (GFM) 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 Generic Function Module (GFM) can withstand. The cause of the excessive current draw MUST be corrected before a new Generic Function Module (GFM) is installed. ADDRESS all other DTCs first. After the cause of the concern is corrected, INSTALL a new Generic Function Module (GFM). Refer to Generic Function Module (GFM) . |
