Immobilizer System Description

Immobilizer System Description

The vehicle is equipped with a Type IV immobilizer system that will disable the vehicle unless a programmed ignition key is used.

This system consists of a transponder, an immobilizer control unit-receiver, immobilizer indicator, imoes unit, and the PCM.

When the immobilizer key is inserted into the ignition switch and turned to the ON (II) position, the immobilizer control unit-receiver sends power to the transponder in the ignition key. The transponder then sends a coded signal back to the immobilizer control unit-receiver which sends a coded signal to the imoes unit, which confirms the code and signals the PCM to supply power to the fuel pump circuit. A handshake with the HDS is required at PCM or imoes unit repair or replacement, and all keys are required at immobilizer control unit-receiver repair or replacement.





- If a programmed key has been used, the immobilizer indicator will come on for about 2 seconds, then go off.
- If the wrong key has been used or the code was not received or recognized by the unit, the indicator will come on for about 2 seconds, then it will blink until the ignition switch is turned to LOCK (0).
- When the ignition switch is turned to LOCK (0), the indicator will blink for 5 seconds to signal that the unit has reset correctly, then the indicator will go off.
