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

Has a problem been found?

	▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Next" procedure.

Ignition "OFF".

Disconnect EPB Switch and EPB ECU main harness connector.

Measure resistance between Signal(1,2,3,4) terminal of EPB Switch harness connector and Signal(1,2,3,4) terminal of EPB ECU harness connector.

Measure resistance between Signal(1,2,3,4) terminal of EPB Switch harness connector and chassis ground.

Is the measured Valule within specification?

	▶ Go to "Component Inspection" procedure.
	▶ After inspecition the signal line between EPB ECU & EPB switch for O/C or S/C, perform verificaiton of vehicle repair
