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 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.
	▶ Go to "Check ESCL Circuit" procedure.

IG KEY OFF.

Disconnect ESCL control Module, SMK Unit connector.

Measure resistance between all the terminals of ESCL harness connector and chassis ground.

Is the measured resistance within specification ?

	▶ Go to "Check short to battery in ESCL harness" procedure.
	▶ Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.

IG KEY OFF.

Disconnect ESCL control Module, SMK Unit connector.

Measure resistance between each terminal of ESCL control Module harness connector and chassis ground.

Is the measured voltage within specification ?

	▶ Go to "check open in ESCL harness" as follows.
	▶ Repair or replace the short to battery as necessary and then, go to 'Verification of Vehicle Repair" procedure.

IG KEY OFF.

Disconnect ESCL control Module, SMK Unit connector.

Measure resistance between one and the other terminal of ESCL control module harness connector or IPM harness connector.

Is the measured resistance within specification ?

	▶ Check poor connection between harness connector and ESCL Control Module, SMK Unit : Thoroughly check the looseness, poor connection, bent, corrison, contamination, deformation or damage of connector. Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure. ▶ After replacing ESCL control module or SMK Unit, perform Key teaching procedure with scantool.
	▶ Repair open in harness or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.
