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 "Control Circuit Inspection" procedure.

Ignition "OFF".

Disconnect LH EPB actuator connector.

Ignition "ON".

Measure voltage between Motor + terminal of EPB Actuator and chassis ground.

Measure voltage between Motor - terminal of EPB Actuator and chassis ground.

Measure resistance between Motor + and Motor - of EPB Actuator harness connector.

Is measured within specification?

	▶ Go to "Component Inspection" procedure.
	▶ Repair open or short in control circuit of EPB Actuator harness connector and then go to "Verification of vehicle Repair" procedure.
