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?
YES
- Repair or replace if necessary and go to "Verification of Vehicle Repair" procedure
NO
- Go to "Ground Circuit Inspection" procedure.

Ground Circuit inspection

1. IG "OFF"
2. Disconnector MAFS connector and then IG "ON.
3. Measure the voltage between terminal 1 of MAFS harness connector.
4. Measure the voltage between terminal 1 and 3 of MAFS harness connector.
A. Specification : Voltage difference and "A" and B" is below 200mV








5. Is the measured voltage within the specification?
YES
- Go to "Component Inspection".
NO
- After repairing or replacing contact resistance in ground circuit and open in the MAFS circuit, go to "Verification and Vehicle Repair".
