Mark LT 2WD V8-5.4L VIN 5 (2007)
Normal Operation
For vehicles equipped with remote keyless entry (RKE), the vehicle security module (VSM) monitors the door ajar switch status on circuits 344
(BK/YE), 345 (BK/PK), 346 (BK/WH) and 363 (BK/LB) for a ground supplied through the ajar switches, by circuit 57 (BK) indicating a door has
been opened. The VSM transmits information over the network to indicate door ajar status. The instrument cluster then energizes the interior lamp
circuits, lighting the interior lamps. On vehicles without RKE, the 2 front door ajar circuits 344 (BK/YE) and 345 (BK/PK) are monitored directly by
the instrument cluster.
