W/Harness 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?





Charging System Inspection
1. Engine "ON"
2. Turn ON the all electricity such as Head Lamp, defroster etc.
3. Measure voltage at battery at 2500 RPM.

Specification : Approx. 10.5 ≤ Vbatt ≤ 16

4. Is the measured voltage within specifications?






Power Circuit Inspection

1. Ignition "OFF"
2. Disconnect ECU connector
3. Engine "ON"
4. Measure voltage between ON/START Power terminal of AFLS ECU harness connector and chassis ground.

Specification : Approx. 10.5 ≤ Vbatt ≤ 16




5. Is the measured voltage within specifications?






Ground Circuit Inspection

1. Ignition "OFF".
2. Disconnect AFLS ECU connector.
3. Measure resistance between ground terminal of AFLS ECU harness connector and chassis ground.

Specification : below 1 Ohms




4. Is the measured resistance within specification?
