Rear Fog Lamps Power Distribution

Rear Fog Lamps Power Distribution

Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and fuse 53 of the passenger compartment fuse box (C0632) on an R wire. Fusible link 3 (C0589) provides a constant battery feed to the LCM (C0937) on an R wire.

Fuse 53 (C0583) provides a constant battery feed to the ignition switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) on an R wire. When the ignition switch is turned to the 'auxiliary' position, current flows across the switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) to fuse 9 of the passenger compartment fuse box (C0585) on a PB wire. Fuse 9 (C0587) provides an auxiliary ignition feed to the LCM (C2040) on a PY wire. The LCM (C2039) is earthed on an N wire.

Light Check Module

The Light Check Module (LCM) (C2040) provides a feed to the lighting switch (C0041) on a YB wire. When rear fog lamps are selected, the switch contacts close momentarily. Current flows across the switch to the LCM on an NB wire. Sensing this, the LCM powers the rear fog lamps.

The LCM (C0937) provides a feed to the RH rear fog lamp (C0125) on a YB wire. The lamp is earthed on an N wire. The LCM (C2039) also provides a feed to the LH rear fog lamp (C0121) on a YB wire. The lamp is earthed on an N wire.
