Clutch Switch: Description and Operation
Denso Made System
Idle Switch Circuit
CIRCUIT DESCRIPTION
When the idle switch is turned ON, a signal is sent to the ECU. The ECU uses this signal to correct the discrepancy between the throttle valve position
and the actuator position sensor valve to enable accurate cruise control at the set speed. If the idle switch is malfunctioning, problem symptoms also
occur in the engine, so also inspect the engine.
Clutch Switch Circuit
CIRCUIT DESCRIPTION
When the clutch pedal is depressed, the clutch switch sends a signal to the cruise control ECU. When the signal is input to the cruise control ECU during
cruise control driving, the cruise control ECU cancels cruise control.
