Interior Lighting System DTCS
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 MODULES . TEST the system for normal operation. |
| B1320 | Driver Door Ajar Circuit Open | GO to PINPOINT TEST D . |
| B1328 | Passenger Door Ajar Circuit Open | GO to PINPOINT TEST D . |
| B1331 | Decklid Ajar Rear Door Circuit Failure | GO to PINPOINT TEST F . |
| B1688 | Lamp Dome Input Circuit Short to Ground | GO to PINPOINT TEST D . |
| B2A35 | Interior Lighting Output Circuit Open | If the interior courtesy lamp is inoperative, GO to PINPOINT TEST C
. If the interior courtesy lamp stays on continuously, GO to PINPOINT TEST D . |
| B2A36 | Interior Lighting Output Circuit Short to Ground | GO to PINPOINT TEST C . |
| B2A38 | Floor Lamp Circuit Short to Ground | DIAGNOSE all other DTCs and symptoms first. If no other DTCs or symptoms are present, INSPECT the SJB and C2280A for bent pins, loose or corroded connections. If no concerns are found, INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation. |
| B2A3A | Puddle Lamp Output Circuit Short to Ground | DIAGNOSE all other DTCs and symptoms first. If no other DTCs or symptoms are present, INSPECT the SJB and C2280C for bent pins, loose or corroded connections. If no concerns are found, INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation. |
