Direction indicators and hazard warning lamps

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Land Rover Discovery, 2003 Land Rover Discovery, 2002 Land Rover Discovery, 2001 Land Rover Discovery, and 2000 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.

The direction indicator lamps are operated from a three position direction indicator switch on the left hand, steering column stalk. The BCU only allows the lamps to work as direction indicators when the ignition switch is in position II. The BCU also controls the lamps to operate as hazard warning lamps and as a visual warning for the anti-theft system, in which cases all lamps flash simultaneously irrespective of the ignition switch position.

System control of the direction indicators and hazard warning lamps is provided by the BCU operating with the IDM and two electronic relays located in the passenger compartment fuse box. The IDM and relays are integral parts of the passenger compartment fuse box and cannot be serviced individually. The serial data bus is used for communication of status and operation requests between the BCU, IDM and instrument pack.

The hazard warning lamps are operated from a latching pushbutton switch located on the fascia.

All direction indicator/ hazard warning lamp bulbs are rated at 5 Watts.
