Anti-Theft System: Description: Passkey(R): Notes

The Personal Automotive Security System (PASSKey(R)) is standard equipment on this vehicle. The system is designed to prevent vehicle theft by disabling the engine unless a key with a specific electrical resistance is used in the steering column. The PASSKey(R) system and the Universal Theft Deterrent system operate completely separate. The components of the system are the ignition key, the steering column lock cylinder, the PASSKey(R) module, the starter enable relay, and the Powertrain Control Module (PCM). See Fig 1 .
