W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness 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 ?






Power Circuit Inspection

1. Engine "OFF".
2. Disconnect Belt tension sensor connector.
3. Ignition "ON" & Engine "OFF".
4. Measure voltage between terminal 1 of the Belt tension sensor connector and chassis ground.

Specification : Approx. 5V





5. Is the measured voltage within specifications ?






Ground Circuit inspection

1. Engine "OFF".
2. Disconnect Belt tension sensor connector.
3. Measure resistance between terminal 2 of the Belt tension sensor connector and chassis ground.

Specification : 0 ohms





4. Is the measured resistance within specifications ?






Signal Circuit Inspection

1. Connect Belt tension sensor connector & PODS ECU.
2. Ignition "ON" & Engine "OFF".
3. When mounting seat belt, check belt tension signals for change for various belt tension.
4. Measure voltage between terminal 3 of the Belt tension sensor connector and chassis ground.

Specification : approx. 0 - 5V





5. Is the measured voltage within specifications ?
