Taurus AWD V6-3.5L (2009)
NOTE: Time out is 1 minute if the vehicle has less than 80 km (50 miles).
The battery saver time-outs are as follows:
-
Courtesy lamps = 10 minutes
-
Demand lamps = 10 minutes
Field-Effect Transistor (FET) Protection
The SJB utilizes a Field-Effect Transistor (FET) protective circuit strategy for many of its outputs (for example, the headlamp output circuit). Output
loads (current level) are monitored for excessive current (typically short circuits) and are shut down (turns off the voltage or ground provided by the
module) when a fault is detected. A continuous DTC is stored at that time of the fault. The circuit then resets after an ignition cycle or customer demand
of the function (switching the component on, 30-minute battery saver being energized). When an excessive circuit load occurs several times, the module
shuts down the output until a repair procedure is carried out. At the same time, the continuous DTC that was stored on the first failure can not 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 until a successful
on-demand self-test proves that the fault has been repaired. After the on-demand self-test has successfully completed (no on-demand DTCs present), the
continuous DTC clears and the circuit function returns.
Each circuit has 3 predefined levels of short circuit tolerance established in the module based on each circuits' capability. When the first or second level
is reached, the continuous DTC associated with the circuit sets along with DTC B106E. These DTCs may be cleared using the Clear DTC Operation on
the scan tool as long as the fault itself has been corrected. If any of the circuits are shorted past the third level, then DTCs B106F and B1342 set along
with the associated continuous DTC. This DTC cannot be cleared and a new module must be installed.
The SJB FET protected output circuits for the interior lighting system are for the puddle lamps and courtesy lamp output circuits.
