Terminal and Connector Inspection
1.

Many malfunctions in the electrical system are caused by poor harness(es) and terminal condition.

Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.

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

3.

Has a problem been found?

▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.

▶ Go to "Power circuit inspection" procedure.

Power Supply Circuit Inspection
■ Power Supply Check
1.

Ignition "ON" & Engine "OFF".

2.

Disconnect the Yaw rate & lateral G sensor connector.

3.

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

Specification : Approx. B+

4.

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".

Ground Circuit inspection
■ Open Check
1.

Ignition "OFF".

2.

Disconnet the yaw rate & lateral G sensor harness connector.

3.

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

Specification : Approx. below 1Ω

4.

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.

CAN Circuit Inspection
■ Open Check
1.

Ignition "OFF".

2.

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

3.

Measure resistance between CAN HIGH( LOW) terminal of the HECU harness connector and CAN HIGH( LOW) terminal of the Yaw rate & lateral G sensor harness connector.

Specification : Approx. below 1Ω

4.

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.
