EXTERIOR LAMPS - Rear Fog Lamps

EXTERIOR LAMPS - Rear Fog Lamps

DESCRIPTION

The rear fog lamps only operate when the headlamps are illuminated and the ignition switch is in position "II". The non-latching switch is positioned adjacent to the HRW switch on the dash panel. When the rear fog lamps are switched on, the instrument pack warning lamp also illuminates. The fog lamps are automatically switched off every time the ignition is turned off.

OPERATION

Feed from the battery positive terminal is connected to the engine compartment fuse box (C0632-1) by a brown wire. Current flows through fusible link 5 and fusible link 6, which are connected in parallel.

Fusible link 6 (C0571-3) supplies a feed to the lighting switch (C0041-1) on a brown/blue wire. With the lighting switch in either the side or main beam position, current flows across the switch (C0041-4) to the headlamp relay (C0282-2) on a blue wire. As the relay is not energised, the relay switch is open, thus preventing current flow.

Fusible link 5 (C0570-2) supplies a feed to the ignition switch (C0028-1) on a brown/white wire. With the ignition switch in position ’II’ (C0094-1) current flows across the switch to fuse 7 of the passenger compartment fuse box (C0580-9) on a white wire. Fuse 7 (C0580-14) supplies a feed to the headlamp relay (C0282-4) on a white/green wire. The relay (C0282-6) is earthed on a black wire.

With the relay energised the relay switch closes. This allows current to flow across the relay (C0282-2 & C0282-8) to fuse 19 of the passenger compartment fuse box (C0581-17) on a blue wire. Fuse 19 (C0581-18) is connected to the rear fog guard lamp ECU (C0543-2) by a blue/purple wire. The ECU (C0543-1) is earthed on a black wire.
