Neutral Safety Switch: Testing and Inspection
DIAGNOSIS AND TESTING - CLUTCH INTERLOCK/UPSTOP SWITCH
The LHD clutch interlock/upstop switch is an assembly consisting of two switches: an engine starter inhibit switch (interlock) and a clutch pedal
upstop switch (Fig. 9).
The RHD clutch interlock/upstop switch (Fig. 10) consists of a single, multi-function switch that is activated by the hydraulic clutch master cylinder
push rod.
CLUTCH INTERLOCK SWITCH
Mechanical Test
1. With the park brake set and the transaxle IN NEUTRAL, turn the ignition key to the start position. 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.). Make sure the clutch pedal
lever contacts and fully closes the switch on LHD applications, and for proper installation of the master cylinder push rod/bushing on the pedal pin
on RHD applications.
Electrical Test
1. Move ignition key to the "OFF/LOCK" position and remove key
2. Set park brake.
