PASS-Key II

PASS-Key II is a system that prevents the vehicle from starting by disabling the fuel injection system and starter circuit under possible theft situations.

When a key is inserted in the ignition, contacts located in the ignition cylinder contact the resistor pellet in me key. The Instrument Panel Cluster (IPC) measures the resistance of the key pellet and then compares it to the one stored in the IPC's memory. If the key pellets value matches, the IPC grounds the Starter Enable Relay, allowing the starter to operate. The IPC also sends a Class 2 message to the Powertrain Control Module (PCM). The PCM will then enable fuel.
