Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminal connections.
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

Check voltage
1. IG "OFF" & Disconnect OCV connector.
2. IG "ON".
3. Measure voltage between power terminal of OCV harness connector and chassis ground.

Specification : B+





4. Is the measured voltage within specification ?






Control Circuit Inspection

Check short to ground
1. IG "OFF" & Disconnect OCV connector.
2. IG "ON".
3. Measure voltage between control terminal of OCV harness connector and chassis ground.

Specification : Approx. 3.2V





4. Is the measured voltage within specification ?
