Toyota Harrier ASU60/ASU65 Direct Fuel Injector Wiring Diagram

[Roland.O]

This diagram is necessary for circuit tracing, power and ground verificatoin and high voltage signal analysis for the direct injection circuits(f3 to f6). It provides pin configurations and module paths needed to scope cylinder specific control pulses and check the integrity of the lines between the injectors and the ECM. Attempting to resolve a direct injection circuit misfire without factory procedures poses safety and equipment risks. The systems operate under high voltage and can easily destroy testing equipment and shock you. Other risks include damage to the ECM and programming faults.

Common questions that this diagram answers​

1. What is the pinout chart for the No. 1 direct fuel injector f3 connector on a Toyota Harrier ASU60/ASU65?
2. How do I check for high-voltage pulse commands at the cylinder 4 injector f6 on an ASU60/ASU65?
3. What are the factory wire colours for the direct fuel injector harness on a Toyota Harrier 8AR-FTS engine?
