Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found?

	▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Power Circuit Inspection" procedure.

Ignition "ON" & Engine "OFF".

Measure voltage between power terminal of the G-YAW RATE sensor(G-sensor) harness connector and chassis ground.

Is the measured value within specifications?

	▶ Go to "Ground Circuit Inspection" procedure.
	▶ Repair open or short in power circuit between the G-YAW Rate sensor(G-sensor) harness connector and HECU harness connector and then, go to "Verification of vehicle Repair" procedure.

Ignition "OFF" & Engine "OFF".

Disconnect the G-YAW RATE sensor(G-sensor) connector.

Measure resistance between ground terminal of the G-YAW RATE sensor(G-sensor) harness connector and chassis ground.

Is the measured value within specifications?

	▶ Go to "Signal Circuit Inspection" procedure.
	▶ Repair open or short in ground circuit between the G-YAW Rate sensor(G-sensor) harness connector and HECU harness connector and then, go to "Verification of vehicle Repair" procedure.

Ignition "ON" & Engine "OFF".

Disconnect the G-YAW RATE sensor(G-sensor) connector and HECU connector.

Measure resistance between signal terminal of the G-YAW RATE sensor(G-sensor) harness connector and the G-YAW RATE sensor(G-sensor) signal terminal of the HECU harness connector.

Is the measured value within specifications?

	▶ Go to "Component Inspection" procedure.
	▶ Repair open or short in signal circuit between the G-YAW RATE sensor(G-sensor) harness connector and HECU harness connector, and then go to "Verification of vehicle Repair" procedure.
