Courtesy headlamps: Notes

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.

This feature activates the headlamps for 30 seconds when the lock button on the remote transmitter is held down for longer than 1 second. The headlamps will extinguish if the BCU receives either a lock or an unlock signal from the remote transmitter.

The BCU checks the status of the following inputs to determine the correct qualifying conditions for requesting courtesy headlamps:

Ignition state.
Remote locking request.
Remote unlocking request.
Lazy locking request.

If the ignition is off and a lazy locking request is received, the courtesy headlamps are switched on and an internal timer is turned on in the BCU which operates for 30 seconds. If the 30 second timer expires or a request for remote locking or remote unlocking is received, the courtesy headlamps will be turned off.

When main beam is selected, the IDM also provides a signal to the instrument pack to switch on the main beam warning lamp. An additional signal 'main beam indicator disable' is used to prevent the daylight running lamps illuminating the main beam indicator when the main beam is in the daylight running lamp state and the main beam indicator disable signal is on.
