Toyota Harrier (ASU60 / ASU65) ECM Connector Pinout

[Roland.O]

This factory ECM connector pinout chart gives the terminal assignments, voltage thresholds and cuircuit functions for A16 and D60 plugs. It gives the precise steps needed to trace broken engine sensor wires, test critical grounds and isolate hardware faults. Attempting to probe the complex ECM connectors without the OEM pin assignment chart is highly risky and you can short live power feeds and ruin sensitive logic circuits. This can also cause permanent ECM damage and programming failures.

Common questions that this diagram answers​

1. What is the pinout chart for the Toyota Harrier ASU60/ASU65 ECM A16 connector?
2. How do I test engine control module power and ground circuits on a Toyota Harrier ASU60/ASU65?
3. Which terminal on the Toyota Harrier ASU60/ASU65 D60 ECM connector controls the main relay signal?
4. What are the voltage specifications for sensor reference pins on a Toyota Harrier 8AR-FTS ECM?
