PINPOINT TEST 1: DTCs B106E/B106F - SOLID STATE DRIVER DISABLED/MODULE DISABLED - HYBRID
Normal Operation
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, see 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, the SJB must be replaced after the fault condition has been corrected.
Possible Causes
- Output circuit short to ground or voltage
- SJB
Diagnostic Procedure
CAUTION:If DTC B106F is present and the SJB is to be replaced, the fault condition must be corrected first. Failure to correct the fault condition first may cause damage to the new SJB, resulting in a repeat repair.
CAUTION:If DTC B106F is present, DTC B1342 may also be present. At this time, ignore these DTCs and follow the necessary diagnostics to resolve DTC B106E and any other DTCs that are present. DTC B106E will be present only when there is another DTC due to a software issue or a circuitry issue that must be resolved before another self-test is run. Each time a self test is run, 1 of the 4 thresholds is used. Once the 3 thresholds are used, DTCs B1106F and B1342 will be present and the SJB must be replaced. All other DTCs MUST be resolved first or the new SJB will have its 3 thresholds used with each self-test that is run.
