Disconnect the Injector and PCM/ECM connector and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.

Connect the GDS and go to “Current Data”.

Monitor Injector 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 "Control Circuit Inspection" procedure.

IG "OFF". Disconnect injector connector.

IG "ON".

Measure voltage between injector control terminal of injector harness connector and chassis ground.

Is the measured voltage within specification ?

	▶ Go to "Component Inspection" procedure.
	▶ Go to "Check short to battery in harness" as follows.

IG "OFF". Disconnect injector connector and PCM/ECM connector.

Measure resistance between power and control terminals of injector harness connector.

Is the measured resistance within specification ?

	▶ Go to "Component Inspection" procedure.
	▶ Repair short to battery in harness. Go to "Verification of Vehicle Repair" procedure.
