The vehicle is equipped w i t h an immobilizer system that w i l l disable the vehicle unless the proper ignition key is used.
This system consists of a transponder located in the ignition key, an immobilizer control unit-receiver, an indicator
light, and the PCM.
When the key is inserted in 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 w h i c h then sends a coded signal to the PCM.
