SMART JUNCTION BOX (SJB) DIAGNOSTIC TROUBLE CODE (DTC) LIST
| DTC | Description | Action |
|---|---|---|
| B106E | Solid State Driver Disabled Due to Short Circuit | The module has temporarily disabled an output because an excessive current draw exists (such as a short to ground). The Smart Junction Box (SJB) 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. |
| B106F | Module Disabled Due to External Fault | 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 SJB can withstand. The cause of the excessive current draw MUST be corrected before a new SJB is installed. ADDRESS all other DTCs first . After the cause of the concern is corrected, INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULE Article. TEST the system for normal operation. |
