Look at the wiring diagram and check system s circuit. Then check the switch, relay, fuse, ground, etc.

LOCATION AND REPAIR OF TROUBLE

Using the diagnostics, narrow down the causes.

If necessary, use a voltmeter, ohmmeter, etc.

Before replacing certain component parts (switch, relay, etc.), check the power supply, ground, for open wiring harness, poor connectors, etc. If no
problems are encountered, check the component parts.

CHECK SYSTEM OPERATION

After repairing, ensure that the system operates properly.
