When a repetitive fault causing a circuit overload is detected on certain output circuits, the Smart Junction Box (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. When the on-demand self-test has been run after all faults have been corrected, any DTCs related to the fault are cleared.
- DTC B106E (Solid State Driver Disabled Due to Short Circuit) - sets when the SJB has disabled a circuit due to a repetitive fault causing a circuit overload. For a complete list of corresponding DTCs, refer to the PRINCIPLES OF OPERATION .
- DTC B106F (Module Disabled Due to External Fault) - sets when one or more output functions are permanently disabled due to a repetitive circuit overload fault. When DTC B106F is present (DTC B1342 may also be present), the SJB must be replaced after the fault condition has been corrected.
This pinpoint test is intended to diagnose the following:
- Output circuit short to ground or voltage
- SJB
