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.
