1 - INTERLOCK/UPSTOP SWITCH CONNECTOR
  1. Move ignition key to the "OFF/LOCK" position and remove key.
  2. Set park brake.
  3. Disconnect the clutch interlock/upstop switch connector (1). See Fig 1.
  4. Using an ohmmeter, check for continuity between terminals 2 & 3 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 ohmmeter should show continuity (0 ohms).
  6. For RHD applications, disconnect the push rod from the pedal pin and actuate the push rod by hand to close the switch. The ohmmeter should show continuity (0 ohms).
  7. If ohmmeter readings do not fall within these ranges, the switch assembly, or the pedal bracket assembly, is defective and should be replaced. If the switch tests OK, wiring is defective.
