Just got another cheap eeprom programmer and the crimp for the SMD chip to read the data. As a backup solution if the OBD communication is not successful.

@BCX You tried your car(year 2000) uses OBD pin 7 for the SRS communication and the software was OK to use. For the rest of us, it seems that non-year 200 uses OBD pin 12 for the SRS. Just an idea. I have spare SRS on bench to test, how about I route the communication pin from OBD pin12 to OBD pin7, and see your software works fine or not. It's worth to try, isn't it.

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

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.

BTW, from your software log, it would "Connecting to ECU". Can you make a version without checking ECU respond? Or make it selectable whether checking ECU or not checking. Maybe my test bench here only has SRS and no ECU, so the software stopped if ECU connection failed.

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.

Ok, understand. So, may need to wait you to get the SRS from the Magna first.
