Switch Adjustment

Ensure engine does not start when clutch pedal is released. Ensure engine starts when clutch pedal is fully depressed. On Corolla, ensure clearance "A" is greater than 0.04" (1.0 mm) when clutch is fully depressed. See Fig 1.
On all models, if system is not operating correctly, check clutch start switch. With switch in ON (pushed) position, continuity should exist. With switch in OFF (free) position, continuity should not exist. See CLUTCH SWITCH PLUNGER CONTINUITY SPECIFICATIONS table. See Fig 2. Replace or adjust switch as necessary.
