1.

Many malfunctions in the electrical system are caused by poor harness and terminal condition.

Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.

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

3.

Has a problem been found?

▶ Repair if necessary and then go to "Verification of Vehicle Repair" procedure.

▶ If it is 'Open in Signal / Ground', go to "Chcek Open" of "Signal Circuit Inspection" procedure.

▶ If it is 'Short to battery in Signal', go to "Chcek Short to battery" of "Signal Circuit Inspection" procedure.

▶ If it is 'Short to ground in Signal', go to "Chcek Short to ground" of "Signal Circuit Inspection" procedure.
