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