The Engine Control Diagram for the Toyota Harrier (ASU60 / ASU65) provides essential engine control systen schematics that you require for circuit tracing, power and ground verification and sensor/actuator tracking. It allows you to isolate faults between the ECM and peripheral components using pricise wiring layouts.
Some technicians attempt to diagnose complex engine control issues without the OEM diagram but this carries a major risk of misdiagnosis or accidental damage to the module. This may cause you to waste time or replace components that were initially not faulty.
With this diagram, you can confidently trace faults, execute continuity tests and resolve complex powertrain electrical problems. I have attached a screenshot of the complete OEM manual with this diagram, please use the link below to pay and access the manual.
