Added a switch so that I can select using OBD pin7 or pin12. As your expectation, it is not working both OBD pin7 or pin12. Same error found.Worth a shot but I suspect the handshake will be different as its not using kline, so won't need or use five baud init.
I plan to get a hold of a srs computer from a Magna at wrecker as see how it communicates with MUT. Magna uses pin12
Ok, understand. So, may need to wait you to get the SRS from the Magna first.Its not connecting to engine ECU, its referring to SRS ECU.
ECU meaning Electronic Control Unit.
I will change the text to make it clearer.
