Indicator Lamp, Rear Fog Lamp

Indicator lamp, rear fog light

Schematic:

The indicator lamp for the rear fog light is situated in the upper RH corner and informs the driver when the rear fog light is switched on.

The lamp is powered from the main instrument unit and grounded internally by the main instrument unit. DICE continuously sends bus information REAR FOG LIGHT, unit ON/OFF.

On receiving REAR FOG LIGHT ON, the control module grounds the output of the lamp which then lights up.

If DICE changes the status of the bus information to REAR FOG LIGHT OFF, the lamp goes out.

Diagnostics
The function has its own diagnostics in the sending system.
