Headlamp Levelling Description

Headlamp Levelling Description
The headlamp levelling is operated from a four position switch located on the fascia. The switch operates a motor located in each headlamp unit which moves the headlamp position to allow for changes in vehicle attitude due to load or passenger distribution.

The headlamp levelling operates when the side lamps or headlamps are on and is independent of the ignition switch position.

Headlamp Levelling Supply

Circuit supply
A feed from the battery positive terminal is connected by an R wire to the engine compartment fusebox where it passes through fusible link 13.

When the lighting switch is in the side lamp or headlamp position, the feed from fusible link 13 flows to the lighting switch on an NG wire. The feed flows through the lighting switch contacts and is connected to the passenger compartment fusebox on an R wire, where it passes through fuses 11 and 33.

Headlamp levelling motor supply
Fuse 11 supplies a feed to header C0288 LHD/C0286 RHD on an RB wire. Fuse 33 supplies a feed to the headlamp levelling switch on an RO wire via header C0759.

From the header C0288 LHD/C0286 RHD, the feed is connected to the LH headlamp levelling motor on an RB wire. The earth path from the LH headlamp levelling motor is on a B wire to earth point C0564.

A second feed is connected to the RH headlamp levelling motor on a RB wire from the header C0288 LHD/C0286 RHD. The earth path from the RH headlamp levelling motor is on a B wire to earth header C0018.
