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".

Disconnect the Yaw rate & lateral G sensor connector.

Measure voltage between power terminal of the yaw rate & lateral 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 battery and Yaw rate & Lateral G sensor harness connector. Check for open or blown fuse referring to "Circuit Diagram". ▶ If there is no problem in circuit, Go to "Verification of vehicle Repair" procedure.

Ignition "OFF"

Disconnet the yaw rate & lateral G sensor harness connector.

Measure resistance between ground terminal of the yaw rate & lateral G sensor harness connector and chassis ground.

Is the measured resistance within specifications?

	▶ Go to "CAN Circuit Inspection" procedure.
	▶ Repair open between ground teminal of the yaw rate & lateral G sensor harness connector and chassis ground. If there is no problem in circuit, Go to "Verification of vehicle Repair" procedure.

Ignition "OFF".

Disconnet the HECU harness connector and yaw rate & lateral G sensor harness connector .

Measure resistance between CAN HIGH terminal of the HECU harness connector and CAN HIGH terminal of the yaw rate & lateral G sensor harness connector.

Measure resistance between CAN LOW terminal of the HECU harness connector and CAN LOW terminal of the yaw rate & lateral G sensor harness connector.

Is the measured resistance within specifications?

	▶ Go to "Component inspection" procedure.
	▶ Repair open in CAN BUS line between HECU harness connector and Yaw rate & lateral G sensor harness connector and then go to "Verification of Vehicle Repair" procedure.
