Disconnect the ECTS 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 ECTS 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 "Signal Circuit Inspection" procedure.

IG "OFF". Disconnect ECTS connector.

IG "ON".

Measure voltage between signal terminal of EOTS harness connector and chassis ground.

Is the measured voltage within specification ?

	▶ Go to "Ground Circuit Inspection" procedure.
	▶ If the voltage is 0V, go to "Check open in harness" as follows. If the voltage is more than 5.1V, repair short to battery in harness and go to "Verification of Vehicle Repair" procedure.

IG "OFF". Disconnect ECTS connector and PCM connector.

Measure resistance between signal terminal of ECTS harness connector and ECTS signal terminal of PCM harness connector.

Is the measured resistance within specification ?

	▶ Go to "Ground Circuit Inspection" procedure.
	▶ Repair open in harness. Go to "Verification of Vehicle Repair" procedure.

IG "OFF" and disconnect ECTS connector and then IG "ON".

Measure voltage between signal terminal of ECTS harness connector and chassis ground.(Measurement "A")

Measure voltage between signal and ground terminals of ECTS harness connector.(Measurement "B")

Is the measured voltage within specification ?

	▶ Go to "Component Inspection" procedure.
	▶ Repair contact resistance or open in harness. Go to "Verification of Vehicle Repair" procedure.
