F 150 2WD Pickup V8-4.6L SOHC VIN W (1998)
Arm/Disarm Switch: Description and Operation
The door disarm switches are attached to both the LH and RH lock cylinder. The door disarm switch must be triggered before the mechanical lock
unlocks. This prevents the anti-theft alarm from activating when it should have been disarmed.
The door open warning lamp switch communicates with the RAP module through the Generic Electronic Module (GEM). This input to the RAP module
will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the
autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, REFER to the Keyless Entry system.
