Toyota Harrier ASU60/ASU65 Smart Entry and Start Wiring Diagram

[Roland.O]

This diagram is essential for network communications analysis, circuit tracing, power and ground verification within passive entry and ignition system. It provides precise connection between the smart key ECU, push button start switch, electrical steering lock and internal/external low frequency oscillator antennas required for detection. Attempting to troubleshoot the electronic keyless system without factory schematics risks severe misdiagnosis, programming failure or permanently locking out the Harrier's immobiliser network.
