its states the voltage at (circuit 30 and or 31 is faulty), or diagnosic link to multiplexer is not connected, and etc. I went back to the pin number 30 and turns out that I was following the wrong wire to the relays. So I am going to try and find where the wire leads to. I know that in pin number 30 the wire is yellow. I am not sure if that can help. Thanks!!
