Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

Has a problem been found?

	▶ Repair as necessary and go to "Verification of vehicle Repair" procedure.
	▶ Go to " Signal Circuit Inspection " procedure.

IG "OFF" and disconnect the clutch switch connector.

IG "ON".

Measure voltage between Signal terminal of clutch switch harness connector and chassis ground.

Measure resistence between power terminal of clutch switch harness connector and signal terminal of ECU harness connector.

Are the measured values within specification?

	▶ Go to "Ground Circuit Inspection" procedure.
	▶ Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedue.

IG "OFF" and disconnect the clutch switch connector.

IG "ON".

Measure resistence between ground terminal of clutch switch harness connector and chassis ground.

Is the measured resistence within specification?

	▶ Go to "Component Inspection" procedure.
	▶ Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedue.
