Ignition switch
Description of operation
If the clutch pedal is pressed when driving at a constant
speed, the clutch pedal position switch is turned ON and a
cancel signal is input to the control unit and the determined
driving speed is canceled because current flows to the
clutch pedal position switch junction block from the control
unit and to ground.

Description of operation
The accelerator switch is a switch that detects the operational
status of the accelerator pedal; it is one of the sensors of the
automatic transaxle.
Because the status of the accelerator pedal during constant-
speed driving is non-operational, the ground circuit (transistor
constant-speed driving in order not to interfere with the function
of the automatic transaxle.
