Q: What is the function and adjustment process of the interlock and clutch pedal position switches on Honda Fit?
A: The interlock switch enables the engine to start only when the clutch pedal is depressed, while the clutch pedal position switch deactivates the cruise control under the same condition. In vehicles lacking cruise control, an adjustment bolt replaces the pedal position switch. Both switches are situated at the top of the clutch pedal, with the interlock switch mounted higher on the bracket and the pedal position switch lower. To replace a switch, disconnect the wiring, loosen and remove the locknut, and take out the switch, then install the new switch in reverse order and adjust it. For adjustment, disconnect the electrical connector, loosen the locknut, and turn the switch. For the clutch pedal position switch, with the pedal released, install the switch so the plunger just contacts the pedal, then screw in an additional 3/4 turn and secure the locknut. For the clutch interlock switch, with the pedal depressed approximately 2-1/2 inches for 2008 and earlier models or 1/2-inch for 2009 and later models, adjust the switch to allow the vehicle to start in this position and tighten the locknut before reconnecting the electrical connector.
