in the switch-half of the wire harness connector with
the clutch pedal released. There should be no conti-
nuity. If OK, go to Step 4. If not OK, replace the
faulty switch.
(4) Check for continuity between the two cavities
in the switch-half of the wire harness connector
again with the clutch pedal depressed. There should
