W/Harness Inspection

4WD Control
P0727 Engine Speed Input Circuit No Signal - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector Inspection

1. Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damge of component.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration,or damage.
3. Has a problem been found?






CAN communication circuit inspection (ECM <--> 4WD ECM)

CAN Line Inspection
1. IG key "OFF".
2. Disconnect ECM and 4WD ECM connector.
3. Measure the resistance between CAN-HIGH terminal of 4WD ECM harness connector and CAN-HIGH terminal of ECM harness connector.
4. Measure the resistance between CAN-LOW terminal of 4WD ECM harness connector and CAN-LOW terminal of ECM harness connector.

Specification :1Ohms below.




5. Is the measured resistance within specification ?
