PINPOINT TEST A: DTCs B106E, B106F

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: If DTC B106F is present and the Smart Junction Box (SJB) is being 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.
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, 1 of the 3 thresholds is used. Once the 3 thresholds are used, DTCs B106F and B1342 are present and the Smart Junction Box (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.
