DTCs & ECU Location
If you ever need access to the ECU in your AU Falcon, it can be found bolted to the very bottom of the A Pillar area of the passenger side of the cabin. This can be useful if you intend on adding a performance chip (such as a J3 chip from T.I. Performance)
The ECU is held in with rivets which will need to be drilled out. when reinstalling, new rivets or tek screws are viable replacements
