F 250 2WD Pickup V6-4.2L VIN 2 (1998)
Lock Cylinder Switch: Description and Operation
The ignition lock anti-theft switch detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is
always monitored by the Remote Anti-theft Personality (RAP) module. This allows the alarm system to be triggered if the ignition lock anti-theft switch
detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
