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?






Signal Circuit Inspection

Check short to battery in harness
1. IG "OFF" and disconnect VPS connector and ECM connector.
2. IG "ON".
3. Measure voltage between VPS signal terminals of VPS harness connector and chassis ground.

Specification : Approx. 0 V








4. Is the measured voltage within specification?






Ground Circuit Inspection

Check open in harness
1. IG "OFF" and disconnect VPS connector.
2. Measure voltage between VPS power terminal of VPS harness connector and chassis ground. (Measurement "A")
3. Measure voltage between VPS power and VPS ground terminals of VPS harness connector. (Measurement "B")

Specification : Voltage difference between measurement "A" and "B" is below 200 mV.
















4. Is the measured voltage within specification?
