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

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found?

	▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

IG key OFF.

Disconnect 'CRUISE REMOCON SWITCH' connector.

IG key ON.

Measure voltage between 'CRUISE MAIN' terminal of 'CRUISE REMOCON SWITCH' harness connector and chassis ground.

Is the measured value within specification?

	▶ Go to "Signal Circuit Inspection".
	▶ Repair short to ground / open between 'CRUISE MAIN' terminal of 'CRUISE REMOCON SWITCH' harness connector and 'Cruise supply' terminal of PCM harness connector, and go to "Verification of Vehicle Repair" procedure.

IG key OFF.
