DESCRIPTION

TRANSPONDER (built-in keys)

When ignition is "ON", the coil supplies energy to the transponder, which in turn accumulates energy in the condenser. Once the energy supply from the coil has stopped, using the stored energyin the condenser, the transponder transmits the ID CODE.

COIL ANTENNA

Supplies energy to the transponder.

Receives signal from the transponder.

Sends transponder signal to the ICM.

IMMOBILIZER CONTROL MODULE

Supplies power to the coil antenna.

Receives and analyzes signal from the coil antenna.

Transmits signal to ICM

Stores VIN which composes of the ID CODE and password.

ENGINE CONTROL MODULE

With the ignition "ON", the ECM receives information from the ICM and permits injection to take place.

KEYS

ID KEY

Must be used first to register the unique ID CODE in the ICM.

This ID CODE is then recorded into the master keys.

MASTER

Once the ID CODE is recorded into the MASTER KEY, this key is for general use.

DATA LINK CONNECTOR

By connecting the voltmeter or HI-SCAN, control module diagnostic code can be read.
