Disconnect the Main Relay and PCM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.

Connect the GDS and go to ""Current Data"".

Monitor Main Relay values in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).

Any change in the values indicates a poor connection. Was a connector problem found?

	▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Power Circuit Inspection" procedure.

IG "OFF". Disconnect the main relay.

IG "ON"

Measure the voltage between power supply terminals of main relay harness connector and chassis ground.

Is the measured voltage within specification ?

	▶ Go to "Control Circuit Inspecition" procedure.
	▶ Check the fuse between battery and main relay. ▶ Repair open or short to ground in power circuits. Go to "Verification of Vehicle Repair" procedure .

IG "OFF". Disconnect the main relay and PCM connector.

Measure the resistance between control terminal of main relay harness connector and chasses ground.

Is the measured resistance within specification ?

	▶ Go to "Check open in harness" procedure.
	▶ Repair short in control harness. Go to "Verification of Vehicle Repair" procedure.

IIG "OFF". Disconnect the main relay and PCM connector.

Measure the resistance between control terminal of main relay harness connector and main relay control terminal of PCM harness connector.

Is the measured resistance within specification ?

	▶ Go to "Component Inspection" procedure.
	▶ Repair open in control harness. Go to "Verification of Vehicle Repair" procedure.
