Toyota Harrier ASU60/ASU65 Airbag ECU Connector Pinout

[Roland.O]

This OEM pinout chart gives the terminal layouts, expected voltage specifications and circuit pathways for the H37 and Q4 plugs. It gives precise steps needed to trace seat belt pre-tensioners, analyse front or side impact sensor loops and resolve faults on the SRS systems. Trying to probe complex SRS module connectors without OEM procedures can trigger accidental airbag deployment or damage terminals.

Common questions that this diagram answers​

1. What is the pinout mapping for the Toyota Harrier ASU60/ASU65 airbag ECU H37 connector?
2. How do I test SRS module power and ground circuits on a Toyota Harrier ASU60/ASU65 safely?
3. Which terminal on the Toyota Harrier ASU60/ASU65 Q4 airbag ECU plug controls the driver squib deployment loop?
4. What are the voltage and resistance specifications for impact sensor circuits at the Harrier ASU60/ASU65 airbag module?
