Description & Operation



The clutch interlock/upstop switch is an assembly consisting of two switches: an engine starter inhibit switch (interlock) and a clutch pedal upstop switch. The switch assembly is located in the clutch/brake pedal bracket assembly, each switch being fastened by four plastic wing tabs.

Clutch Interlock Switch

The clutch interlock switch prevents engine starter operation and inadvertent vehicle movement with the clutch engaged and the transaxle in gear. The switch is open while the clutch pedal is at rest. When the clutch pedal is fully depressed, the pedal blade contacts and closes the switch, sending signal to the PCM, allowing engine starter operation. The interlock switch is not adjustable.

Clutch Pedal Upstop Switch

With the clutch pedal at rest, the clutch pedal upstop switch is closed, allowing speed control operation. When the clutch pedal is depressed, the upstop switch opens and signals the PCM to cancel speed control operation, and enter a modified engine calibration schedule to improve driveability during gear-to-gear shifts. The upstop switch is not adjustable.
