Mechanical Test
(1) With the park brake set and the transaxle IN
NEUTRAL, turn the ignition key to the start posi-
tion. The engine starter should not crank with the
clutch pedal at rest (not depressed). If the starter
cranks, proceed to the electrical test to determine
whether the switch is defective or the circuit is
shorted. If the vehicle does not crank, proceed to the
next step.
(2) With the park brake set and the transaxle IN
NEUTRAL, fully depress the clutch pedal and turn
the ignition key to the start position. The engine
starter should crank. If the starter does not crank,
visually inspect the clutch pedal for obstructions
(floor mat, etc.) and for proper installation of the
master cylinder push rod/bushing on the pedal pin.
Also make sure the clutch pedal lever contacts and
fully closes the switch for LHD applications.
Electrical Test
(1) Move ignition key to the "OFF/LOCK" position
and remove key.
(2) Set park brake.
(3) Disconnect the clutch interlock/upstop switch
connector.
(4) Using an ohmmeter, check for continuity
between terminals 2 & 3 (Fig. 19) with the interlock
switch not depressed (clutch pedal at rest). There
should be no continuity between the terminals (open
circuit).

(5) Fully depress the clutch pedal to close the
switch. The switch button should compress at least
1.25 mm (0.050 in.) for LHD applications. The ohm-
meter should show continuity (0 ohms).
