Cruise Control Cancellation: Function
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.
The cruise control ECU cancels cruise control operation by opening a vacuum control valve in the vacuum pump assembly. This releases the throttle linkage from the control of the pneumatic actuator and returns it to the control of the accelerator pedal.
The set speed will be stored in the cruise control ECU unless:
- The cruise control master switch is turned off.
- The ignition switch is turned off.
If cruise control is deactivated using either of the above methods, the set speed will be erased from the memory of the cruise control ECU.
