IMMOBILIZER

141

Circuit Description

Immobilizer is a device disabling vehicle ignition unless a specific key is used and designed to help prevent
vehicle theft.

Immobilizer is comprised of two devices, a key with encoded transponder and ECM with the same encoding of
the transponder. When a key is inserted into the hole to start vehicle and turned to ON, the ECM reads and
decodes the transponder code and, if the same, starts the engine, it is called immobilizer. It means immobilizer
system disables starting by stopping fuel supply if the code in the transponder does not match the code stored
in ECM each other.
