Immobilizer System Description - Components (Without Keyless Access System)

Immobilizer Indicator 

The immobilizer system turns on the immobilizer indicator on the gauge control module (tach) after the ignition system entering the vehicle ON mode, and then authentication processing starts. The immobilizer indicator goes off after the control unit confirms the chip code is correct. The immobilizer indicator will indicate an abnormality in the system, success/failure of the key authentication.

Ignition Key 

The vehicle equipped with the immobilizer system has an identification marking on the mechanical key. Consider this identification marking as a proof of the vehicle having the immobilizer system.
