I recently received the "no response" alert when trying to connect to my ECU through ECM Link. After troubleshooting using the steps on these two pages:
connectionproblem [ECMTuning - wiki]
diagport-12pin [ECMTuning - wiki]
I have pretty much decided that my ECU must have a problem.
I am getting correct reading from all the pins except pin 1 (diagnostic pin). I have good ground on 12, and a good 4.5v on 10. I have good continuity on all wires between the port and my ecu connector, just no signal coming from pin 1. I also opened up my ECU and verified that there was nothing VISUALLY wrong, at least that I could see.
I upgraded to V3 on 24 Nov by sending it into ECM Tuning. They also replaced the caps, and put a new socket on the board.
Since this is Friday, and they wont be in to contact before Monday, figured I would post up and see if anyone else had any ideas or thoughts on possible problems, or know of something I have not checked.
