System Description
Mechanical key
(Including transponder) Immobilizer key
MICU
(Imoes circuit) Mechanical key
Steering lock assembly Immobilizer-keyless
control unit
ECM/PCMTransmitter
(Including
transponder)
The vehicle is equipped with a type VI immobilizer system that will disable the vehicle unless a programmed ignition
key is used.
This system consists of a transponder combined with a keyless transmitter, immob
ilizer-keyless control unit, the MICU
(has built-in imoes unit), immobilizer indicator, and the ECM/PCM.
When the immobilizer key (programmed by the HDS) is inserted into the ignition switch and turned to ON (II), the
immobilizer-keyless control unit sends power to the trans ponder 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 ECM/PCM and the
MICU (imoes unit). The ECM/PCM and MICU (imoes unit) identify this code signal, then fuel power is supplied.
NOTE: The transmitter is automatically programmed to the vehicle when a transponder is programmed by the HDS.
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 ten times to signal that the unit has reset correctly, then the indicator will go off.
