2427928 - E2031 REAR FOG LAMPS - Description

Description

The vehicle is fitted with an extra bright rear fog lamp, located in the left rear light cluster. The rear fog lamp is activated using the button in the control panel in the centre of the dashboard; when the lights are on, the warning light in the instrument panel comes on.

The switching on of the rear fog lamp is managed by the Body Computer: it is activated in the following conditions:

• go ahead signal with key in ON position (INT);
• signal coming from the switch;
• side lights on signal.
• headlamps signal (dipped or main beam) or fog lights on.

If one of the go ahead signals is missing, the button must be pressed again in order to switch the rear fog lamps on.

The correct operation of the lights is controlled by the rear fog lamp 'check' function: the following are checked:

• open circuit or bulb missing
• short circuit to earth (bulb short circuit or wiring short circuit to earth)
• short circuit to Vbatt (wiring short circuit to Vbatt)

If one of the situations described above is detected, the Body Computer notifies the CAN of the failure state: a special 'failure' warning light comes on in the instrument panel and, at the same time, the information is shown on the display.
