PINPOINT TEST J: DTCs B106E, B106F

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If DTC B106F is present and a new SJB is to be installed, 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.

NOTE: 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 is 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, one of the 3 thresholds is used. Once the 3 thresholds are used, DTCs B106F and B1342 is present and the SJB must be replaced. All other DTCs MUST be resolved first, or else the new SJB begins to have its 3 thresholds used with each self-test that is run.
