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 ?






Control Circuit Inspection

1. Check voltage
(1) IG "OFF".
(2) Disconnect ETS motor & TPS connector.
(3) IG "ON" and ENG "OFF"
(4) Measure the voltage between terminal 2,3 of ETS motor & TPS harness connector and chassis ground.

Specification : Approx. 12V





(5) Is the measured voltage within specification ?





2. Check open in harness
(1) IG "OFF"
(2) Disconnect ETS motor & TPS connector and PCM connector.
(3) Measure the resistance between terminal 2 of ETS motor & TPS harness connector and terminal 2 of PCM harness connector.
(4) Measure the resistance between terminal 3 of ETS motor & TPS harness connector and terminal 1 of PCM harness connector.

Specification : Approx. below 1 ohms





(5) Is the measured resistance within specification ?
