PASSLOCK System Operation

PASSLOCK SYSTEM

The PASSLOCK(TM) System is designed to prevent vehicle theft by disabling the engine unless the PASSLOCK(TM) Lock Cylinder is correctly engaged by a mechanical key. This system is similar in concept to the Passkey System; however, PASSLOCK(TM) eliminates the need for a key mounted resistor pellet. The components of this system are as follows: PASSLOCK(TM) Lock Cylinder, Ignition Switch, Instrument Panel Cluster (IPC), and Powertrain Control Module (PCM).

SYSTEM OPERATION

The PASSLOCK(TM) System is designed to prevent vehicle operation if the mechanical key, in normal operation, will the PASSLOCK(TM) Lock Cylinder. The PASSLOCK(TM) Lock Cylinder will relay a Resistance Code (R-Code) to the Instrument Panel Cluster (IPC). The IPC will determine the validity of the R-Code within a present time window started from an Ignition Switch input and will send a coded password the PCM. When the PCM receives the correct code, it will allow the fuel injectors to operate normally.
