W/Harness Inspection

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
1) Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Go to "Power Supply Circuit Inspection" procedure.

Power Supply Circuit Inspection

1. Ignition "ON" & Engine "OFF".
2. Measure voltage between terminal "3" of the Yaw Rate & Lateral G sensor harness connector and chassis ground.
A. Specification: Approx. 5V




3. Is the measured voltage within specifications ?
YES
1) Go to number 4 (Power Circuit Inspection procedure of pressure sensor).
NO
1) Check for short to GND or short to B+ in the Yaw Rate & Lateral G sensor harness between terminal "3" of the Yaw Rate & Lateral G sensor harness connector and terminal "36" of the HECU harness connector. Repair as necessary and then go to "Verification of vehicle Repair" procedure. If OK, go to "Component Inspection" procedure.
4. Measure voltage between terminal "2" of the pressure sensor harness connector and chassis ground.
A. Specification: Approx. 5V




5. Is the measured voltage within specifications ?
YES
1) Go to "Component Inspection" procedure.
NO
1) Check for short to GND or short to B+ in pressure sensor harness between terminal "2" of the pressure sensor harness connector and terminal "37" of the HECU harness connector. Repair as necessary and then go to "Verification of vehicle Repair" procedure.
