Toyota Harrier ASU60/ASU65 Oil Pressure Switching Valve Wiring Diagram

[Roland.O]

This OEM wiring diagram provides the full circuit paths, wire colours and connector pinouts for the v1 plug assembly. It gives the procedures required to verify solenoid power supply, check driver line continuity and fix engine lubrication control faults. Without this diagram, you can easily create a big problem through incorrect terminal probing which can damage the ECM or not even solve the lubrication control faults anyway.

Common Questions that this diagram answers​

1. What is the pinout mapping for the oil pressure switching valve v1 connector on a Toyota Harrier ASU60/ASU65?
2. How do I test the control signal from the ECM to the oil pressure switching valve on an ASU60/ASU65?
3. What are the factory wire colours for the oil control switching valve harness on a Toyota Harrier 8AR-FTS engine?
4. How do you isolate an open wiring fault from a mechanically seized oil pressure switching valve solenoid for ASU60/ASU65?
