Cancelling

Cruise control is cancelled by pressing the master switch. When cruise control is cancelled, the LED in the master switch extinguishes and the power feed to the interface ECU is disconnected to disable the system. If cruise control is engaged when the master switch is pressed, the interface ECU and the ECM respond in the same way as when cruise control is suspended, except that the interface ECU no longer reacts to inputs from the steering wheel switches.

During the same ignition cycle, if the master switch is pressed again, the interface ECU is re-enabled. Since the output of the RESUME MFL message is inhibited until after the first engagement of cruise control, the interface ECU will not react to an input from the RES switch, and the set speed in the ECM memory is effectively lost to the system. Cruise control only re-engages if the SET+ switch is pressed, when, provided the vehicle is in the correct driving configuration, the ECM adopts the current vehicle speed as the new set speed.
