Immobilizer System Description

Immobilizer System Description

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

This system consists of a transponder, a keyless transmitter, an immobilizer-keyless control unit, an immobilizer indicator, an imoes unit (built into the MICU), and the PCM.

When the immobilizer key (programmed by the HDS) is inserted into the ignition switch and turned to ON (II) position, the immobilizer-keyless control unit sends power to the transponder in the ignition key. The transponder then sends a coded signal back to the immobilizer-keyless control unit, which then sends a coded signal to the imoes unit, which confirms the code and signals the PCM to continue to supply power to the fuel pump circuit.





If the wrong key is inserted into the ignition switch and immediately turned to START (III), temporarily bypassing the recognition code, the engine will start and run for 1-2 seconds, then shut off, and then quickly flash once, then blink until the ignition switch is turned to LOCK (0). When the ignition switch is turned to LOCK (0), the indicator will blink ten times to signal that the unit has reset correctly, then the indicator will go off.
