Disconnect the ETC Motor, TPS 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 TPS 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 ETC Motor & TPS connector.

IG "ON".

Measure voltage between TPS2 signal terminal of ETC Motor & TPS harness connector and chassis ground.

Is the measured voltage within specification ?

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

IG "OFF". Disconnect ETC Motor & TPS connector and PCM connector.

Measure resistance between TPS2 signal and TPS power terminals of ETC Motor & TPS harness connector.(Measurement "A")

Measure resistance between TPS2 signal and ETC motor(+) terminals of ETC Motor & TPS harness connector.(Measurement "B")

Measure resistance between TPS2 signal and ETC motor(-) terminals of ETC Motor & TPS harness connector.(Measurement "B")

Is the measured resistance within specification ?

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

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

Measure voltage between TPS power terminal of ETC Motor & TPS harness connector and chassis ground.(Measurement "A")

Measure voltage between TPS power and TPS ground terminals of ETC Motor & TPS 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.
