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

1. IG "OFF" and disconnect FTPS connector.
2. Measure voltage between terminal 1of FTPS harness connector and chassis ground.
3. Measure voltage between terminal 1 and 3 of FTPS harness connector.

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





4. Is the measured voltage within specification ?






Signal Circuit Inspection

1. Check voltage.
(1) IG "OFF" and disconnect FTPS connector.
(2) IG "ON" & ENG "OFF"
(3) Measure voltage between terminal 2 of FTPS harness connector and chassis ground.

Specification : Approx. 0V





(4) Is the measured voltage within specification ?





2. Check short to battery in harness
(1) IG "OFF" and disconnect FTPS connector.
(2) IG "ON" & ENG "OFF"
(3) Measure resistance between terminals 2 and 1 of FTPS harness connector.

Specification : Infinite





(4) Is the measured resistance within specification ?
