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, an immobilizer control unit-receiver, immobilizer indicator, imoes unit ('07-08 Canada models, '08 USA models), and the PCM.
'07 USA models: When the immobilizer key (programmed by the HDS) 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 then sends a coded signal to the PCM to supply power to the fuel pump circuit.
'07-08 Canada models, '08 USA models: 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 OFF.
- If the ignition switch is turned OFF, the indicator will blink 5 seconds to signal that the unit has reset correctly, then the indicator will go off.
