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?






Ground Circuit Inspection

Check voltage
1. IG "OFF" and disconnect MAFS connector and then IG "ON".
2. IG "ON" & ENG "OFF"
3. Measure voltage between signal and ground terminals of MAFS harness connector (Measurement "B")

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









4. Is the measured voltage within specification?
