Power Distribution Module: Pinpoint Tests
Connector End Views-Smart Junction Box (SJB)
Pinpoint Test 1: DTC B106E - Solid State Driver Disabled Due to Short Circuit
PINPOINT TEST 1: DTC B106E - SOLID STATE DRIVER DISABLED DUE TO SHORT CIRCUIT
Normal Operation
The smart junction box (SJB) controls the output of the daytime running lamps (DRL), fog lamps, one-touch down driver power window, accessory
delay, windshield wiper park/run, windshield wiper speed, and windshield washer. When a repetitive fault causing a circuit overload is detected on any
of the output circuits, the SJB disables the circuit by removing voltage, or ground, to the affected circuit. The circuit remains disabled until the fault is
corrected and an on-demand self-test is run. After the on-demand self-test has been run, any diagnostic trouble codes (DTCs) related to the fault will be
cleared.
DTC B106E - sets when the SJB has disabled a circuit due to a repetitive fault causing a circuit overload. A corresponding DTC for the circuit in
question will also set as follows:
-
DTC B1304 - Accessory delay relay circuit short to B+
-
DTC B1400 - One-touch down window relay circuit short to B+
-
DTC B1432 - Windshield wiper park/run relay circuit short to B+
-
DTC B1436 - Windshield wiper hi/low speed relay circuit short to B+
-
DTC B1460 - Washer pump motor relay circuit short to B+
-
DTC B2512 - Fog lamp relay circuit short to B+
-
DTC B2973 - DRL output short to ground
DTC B106F - sets when one or more output functions are permanently disabled due to a repetitive circuit overload fault. DTC B106F will be set with
DTC B106E. When DTC B106F is present, the SJB must be replaced after the fault condition has been corrected.
