Front Fog Lamps (Description and operation) (page 2 of 2)

A feed from fuse 13 is connected by a PN wire to the passenger compartment fusebox. This feed is connected to the Intelligent Driver Module (IDM) which is integral with the passenger compartment fusebox.

A feed from fusible link 8 is connected on an NW wire to the passenger compartment fusebox and from the fusebox to the ignition switch on an N wire.

Ignition switch supply With the ignition switch in position I, the feed from fusible link 8 flows through the ignition switch to the passenger compartment fusebox on a LGW wire. The feed continues through fuse 26 in the passenger compartment fusebox and is connected by an LG wire to the engine compartment fusebox and the coil of the auxiliary circuits relay. The auxiliary circuits relay coil is connected to earth header C0018, via header C0286 LHD/C0288 RHD on a B wire.

In this condition, the auxiliary circuits relay is energised and the contacts close, allowing the feed from fusible link 7 to pass through the closed contacts to the coil of the front fog lamp relay.

With the ignition switch in position II, a second feed from fusible link 8 flows from the ignition switch to the passenger compartment fusebox on a Y wire. The feed continues through fuse 29 in the passenger compartment fusebox and is connected to the IDM.

In this condition, one of two electronic switches in the IDM closes. The earth path from the IDM is connected from the passenger compartment fusebox to earth header C0551 on a B wire.
