Edge AWD V6-3.5L (2009)
When the excessive circuit load occurs often enough, the module shuts down the output until a repair procedure is carried out. Each FET protected
circuit has 3 predefined levels of short circuit tolerance based on the harmful effect of each circuit fault on the FET and the ability of the FET to
withstand it. A module lifetime level of fault events is established based upon the durability of the FET. If the total tolerance level is determined to be
600 fault events, the 3 predefined levels would be 200, 400 and 600 fault events.
When each tolerance level is reached, the continuous DTC that was stored on the first failure cannot be cleared by a command to clear the continuous
DTCs. The module does not allow this code to be cleared or the circuit restored to normal operation until a successful self-test proves that the fault has
been repaired. After the self-test has successfully completed (no on-demand DTCs present), DTC B106E and the associated continuous DTC (the DTC
related to the shorted circuit) automatically clears and the circuit function returns.
When the first or second level is reached, the continuous DTC (associated with the short circuit) sets along with DTC B106E. These DTCs can be
cleared using the module on-demand self-test, then the Clear DTC operation on the scan tool (if the on-demand test shows the fault corrected). The
module never resets the fault event counter to zero and continues to advance the fault event counter as short circuit fault events occur.
If the number of short circuit fault events reach the third level, then DTCs B106F and B1342 set along with the associated continuous DTC. This DTC
cannot be cleared and the module must be replaced.
