Body Control Unit: Notes
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2004 Land Rover Discovery, 2003 Land Rover Discovery, 2002 Land Rover Range Rover, 2002 Land Rover Discovery, and 2001 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
On manual gearbox vehicles, the BCU provides cruise control lockout or suspend function as described under brake pedal switch.
On vehicles with automatic gearbox, the BCU monitors the status of the brake pedal switch as well as the status of the automatic gearbox gear selector lever. The BCU monitors the gear selector lever to determine which gearbox position the driver has selected. If the BCU detects that the driver has selected park, reverse or neutral, it sends a signal to the cruise control ECU which inhibits cruise operation or deactivates cruise control if it is activated. For SLABS ECU location, see Figure.
