Bulb failure

Bulb failure



SID is informed if a bulb fails by the ICE (brake and rear lights) and a filament monitor (front lights).

Rear lights

In the event of a bulb failure in the rear lights, the SID (pin 8) receives a message from the ICE (pin 37).

If the car is equipped with SID 1/4, the "LIGHT FAILURE" lamp in the main instrument display panel will be grounded via pin 12 of the SID unit.

If the car is equipped with SID 2/3, either of the messages "BRAKELIGHT FAILURE" or "REAR LIGHT FAILURE" will be displayed. In addition, the SID requests (via pins 16 and 17) the main instrument display panel (pins 3 and 4) to turn on the INFO DISPL lamp.

Front lights

In the event of a bulb failure in the front lights, pin 4 of the SID will be grounded by the filament monitor.

If the car is equipped with SID 1/4, the "LIGHT FAILURE" indicator lamp in the main instrument display panel will be grounded via pin 12 of the SID unit.

If the car is equipped with SID 2/3, the message "FRONTLIGHT FAILURE" will be displayed. In addition, the SID requests (via pins 16 and 17) the main instrument display panel (pins 3 and 4) to turn on the INFO DISPL lamp.
