System Operation Spec - Front Sensor

When the system has the power (after IGN ON and D gear), MICOM checks every sensor channel. In case no error is found, it sounds every 500ms afterward. However, when error is found even in one sensor, it sounds buzzer corresponding to faulty sensor instead of the initial starting alarm. When PAS ON switch is OFF, system doesn't work. Function for normal mode entrance is as follows.
