Light Check Module

Light Check Module

The LCM (C2040) is located at the base of the RH 'A' post, and monitors the condition of the fascia mounted rotary lighting switch (C0041) by providing a feed on an NB wire. The LCM can determine the position of the switch by sensing if a feed is returned on a Y (side lamps) or a B (headlamps) wire. The LCM also monitors the condition of the column mounted main/ dipped beam switch (C1832) via a U wire.

Side Lamps

If the LCM detects that side lamps have been selected, it provides a feed to the following:

To the RH side lamp (C0537) on an SU wire To the LH side lamp (C0538) on an SG wire To the RH tail lamp (C0125) on an SW wire To the LH tail lamp (C0121) on an SP wire The rear number plate lamp (C1495) on an SN and an SB wire To the RH front side marker lamp (C0916) on an SU wire (NAS vehicles only) To the RH rear side marker lamp (C0918) on an SU wire (NAS vehicles only) To the LH front side marker lamp (C0917) on an SG wire (NAS vehicles only) To the LH rear side marker lamp (C0919) on an SG wire (NAS vehicles only).

All are earthed on N wires.

Headlamp Dipped Beam

In addition to the lamps outlined in the side lamps section, the LCM will provide feeds to the following lamps if it detects that headlamp dipped beam has been selected:

To the RH headlamp dipped beam bulb (C0011) on a YU wire To the LH headlamp dipped beam bulb (C0009) on a WG wire.

Both are earthed on N wires.

Headlamp Main Beam

In addition to the lamps outlined in the side lamps and headlamp dipped beam sections, the LCM will provide feeds to the following lamps if it detects that headlamp main beam has been selected:

To the RH headlamp main beam bulb (C0011) on a WU wire To the LH headlamp main beam bulb (C0009) on a YG wire.

Both are earthed on N wires.
