Toyota Harrier (ASU60 / ASU65) Audio System Wiring Diagram

[Roland.O]

The Harrier ASU60/ASU65 has a very sensitive Audio system and attempting to trace entertainment network faults or speaker dropouts without factory schematics can quickly turn ugly. It is easy to short circuit sensitive data lines if you start probing the pins blindly. It is also easy to destroy the premium audio amp, display modules or the integrated wiring looms so best to approach the repair with caution.

However, with the official audio system wiring diagram, the work becomes easy and straight forward. You get factory wire colors, connector pin locations and power routing details. Having this data allows you to then proceed cleanly to isolate parasitic battery draws, identify severed speaker lines, etc and trace component faults quickly.
