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 or damage.

	▶ Repair or Replace as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Fault is intermittent and caused either by poor contact in connectors or wiring harness, or it has been repaired and AFLS ECU memory is not cleared yet, and go to "Verification of Vehicle Repair" procedure.
