Description & Operation

1993 Cadillac DeVille Base, 4D SedanSECTION Description & Operation

Vehicles are equipped with Personalized Automotive Security System (PASS-Key II(R)) and may be equipped with Universal Theft Deterrent (UTD) anti-theft system. PASS-Key II(R) system operates using sensing contacts which are located in ignition key lock cylinder. These contact a key resistor pellet which is located on the ignition key. When lock is rotated, battery voltage is applied through appropriate fuse to PASS-Key II(R) decoder module. Pellet resistance is then compared with programmed value in module. The UTD option operates separately from PASS-Key II(R) system. UTD sounds horn and flashes headlights in the event of forced entry through doors or trunk. UTD system does not affect engine starting. Eighty-Eight and Ninety-Eight are not available with UTD.
