Normal Operation
WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
When a repetitive fault causing a circuit overload is detected on certain 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 the DTCs are cleared, and then the self-test is repeated. 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 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 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. 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.
This pinpoint test is intended to diagnose the following:
- Output circuit short to ground or voltage
- SJB
