Cruise Control Cancellation: Function

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.
