Terminal and Connector Inspection
1.

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.

2.

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

3.

Has a problem been found?

YES

a.

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

NO

a.

Go to "Signal Circuit Inspection" procedure.

Signal Circuit Inspection
1.

Ignition "ON" & Engine "OFF".

2.

Measure voltage between terminal "1,2" of the Yaw Rate & Lateral G sensor harness connector and chassis ground.

a.

Specification : Approx. 2.5V

3.

Is the measured voltage within specifications?

YES

a.

Go to "Component Inspection" procedure.

NO

a.

Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal "1,2" of the Yaw Rate & Lateral G sensor harness connector and terminal "41,9" of the HECU harness connector. Repair as necessary and then go to "Verification of Vehicle Repair" procedure. If OK, go to "Component Inspection" procedure.

b.

If OK, Substitute with a known-good Yaw Rate & Lateral G sensor and check for proper operation. If problem is corrected, replace Yaw Rate & Lateral G sensor and then go to "Verification of Vehicle Repair" procedure.

Ground Circuit inspection
1.

Ignition "OFF".

2.

Disconnect Yaw Rate & Lateral G sensor connector.

3.

Measure resistance between terminal "4" of the Yaw Rate & Lateral G sensor harness connector and chassis ground.

a.

Specification : Approx. below 1Ω

4.

Is the measured resistance within specifications?

YES

a.

Go to "Component Inspection" procedure.

NO

a.

Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal "4" of the Yaw Rate & Lateral G sensor harness connector and terminal "23" of the HECU harness connector. Repair as necessary and then go to "Verification of vehicle Repair" procedure.
