Fog lamps

FOG LAMPS

Description

General

The rear fog lamps only operate when the headlamps are switched on, and the ignition switch is in position II. The non-latching fog lamp switch is mounted in the fascia console, and contains a tell-tale LED. The fog lamps are automatically switched off every time the ignition is turned off.

Operation

Power Distribution

Feed from the positive battery terminal (C0192) is supplied to fusible link 5 and fusible link 6 of the under seat fuse box (C0632) on an N wire. Fusible link 6 (C0571) provides a constant battery feed to the lighting switch (C1082 on LHD, C0041 on RHD) on an NU wire.

Fusible link 5 (C0570) is connected to the ignition switch (C1043 on RHD, C0028 on LHD) by an NW wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C1732 on LHD, C0094 on RHD) to fuse 15 of the passenger compartment fuse box (C0580) on a W wire. Fuse 15 (C0580) provides an ignition feed to the headlamp relay coil (C0282) on a WG wire. The relay coil (C0282) is earthed on a B wire.

Fog Lamps

When the lighting switch is moved to the headlamp position, current flows across the switch (C1082 on LHD, C0041 on RHD) to the headlamp relay (C0282) on a BU wire. Current flows across the closed relay switch contacts (C0282) to fuse 26 of the passenger compartment fuse box (C0581) on a U wire. Fuse 26 (C0581) provides a feed to the fog lamp ECU (C1724 on LHD, C0543 on RHD) on a UP wire. The fog lamp ECU (C1724 on LHD, C0543 on RHD) is earthed on a B wire.
