Circuit Description

When the ignition switch is turned ON, ECM transmits the indication ON signal to the combination meter to turn ON the immobilizer indicator light in case that there is not any problem with the immobilizer control system. Then, the combination meter turns ON the light. When the engine is started up, ECM transmits the indication OFF signal to the combination meter to turn OFF the light. Then, the combination meter turns OFF the immobilizer indicator light. However, in case that there is some trouble with the immobilizer control system, the immobilizer indicator light flashes ON and OFF when the ignition switch is turned ON.
