Has a problem been found?

	▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Go to "W/Harness Inspection" procedure.

Ignition "OFF"

Disconnect EPB actuator LH and EPB ECU main harness connector.

Measure resistance between Motor(-),(+) terminal of EPB actuator LH harness connector and Motor(-),(+) terminal of EPB ECU harness connector.

Measure resistance between Motor(-),(+) terminal of EPB actuator LH harness connector and chassis ground .

Is the measured Value within specification?

	▶ Go to " Component inspection " procedure.
	▶ Check for open/short circuit between EPB ECU & actuator on left side and repair it. Then perform verification of vehicle repair
