• If the proper key has been used, the immobilizer indicator light 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 PCM, the indicator light will come
on for about 2 seconds, then it will blink until the ignition switch is turned OFF. For accurate immobilizer system
diagnosis get as much information from the customer as possible. A blinking indicator light means the key was not
recognized.
• If the ignition switch is turned OFF, the indicator will blink for about 5 seconds to signal that the immobilizer system
has been set correctly, then the indicator will go off.

signal. If an intermittent program is suspected, remove the ignition key from the key ring.
