Will a poorly connected OBD dongle/cable cause odd faults/behavior?
I popped a CEL and hooked up my code reader. It's a decent Innova one, not great but we'll above basic.
It showed me the code but then the car went wonky. The entertainment system and the dash both turned off but the car did not die. In a few seconds both came back on but the dash flashed three warnings. First was the wrench symbol with "Check service manual" then "Service Advancetrac" and finally "ECM lost communication". The OBD reader also lost communication. I turned the engine off and pulled the OBD cable and it felt like it was loose coming out.
Later when I started the car there were no more warnings (just the original CEL) and the car ran fine.
I'm leaning towards a loose OBD cable causing some kind of spike but it's really the first time anything like this has happened to me so IDK...
