AUTOMATIC SPEED CONTROL (CRUISE)
5. CANCELLATION
Y27ELOA
When the signals below are input (during fixed-speed driving), conductivity to the electromagnetic clutch is inte-
rupted, thus canceling the ASC system.
1) Stop lamp switch ON (brake pedal depressed)
2)
Clutch switch ON (clutch pedal depressed)
3) Inhibitor switch ON (selector lever at "P" or "N" position)
NOTE
When the brake pedal is depressed and the stop lamp switch is switched ON, the ASC system will
be canceled even if there is wiring damage or disconnection at the fuse for the stop lamp.
