Cruise control
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 BCU processes several signals used for cruise control:
- When the brake pedal is pressed, a low voltage brake lamp signal is sent via the BCU to the cruise control ECU.
- The gear position switch sends an input via the BCU to the cruise control ECU if the selector lever is in Park, Neutral or Reverse.
- A voltage supply is fed from the BCU to the cruise control SET+ switch.
- A voltage supply is fed from the BCU to the cruise control RES switch.
On vehicles with automatic transmission, if the BCU receives an input from the gear position switch or the brake pedal switch, the BCU sends a signal to the cruise control ECU to cancel or inhibit cruise control operation.
