Title: Trying to flash in car. Think I have a noisy K line. Post by: stuklr on April 04, 2014, 07:17:50 AM I am trying to be able to flash my 01 Allroad via OBD. I have always had to bench the ecu because Nefmoto cannot seem to connect to the ecu in car. I have tried removing the cluster fuse #15 and still no result. The ecu in question has been flashed countless times on the bench.
I looked at the wiring diagram and the only things on the K line in this car are the cluster and ECU. Any ideas? Title: Re: Trying to flash in car. Think I have a noisy K line.

Every. Thing. I have never had an issue. Slow init, 38400 baud. Title: Re: Trying to flash in car. Think I have a noisy K line. Post by: stuklr on April 04, 2014, 07:56:04 AM So, just try slowing it down? I never thought of that. I just always let it go auto. Will try that out.
I was thinking about my own K line just for flashing. Like installing a switch to deactivate the old line when I am programming. Title: Re: Trying to flash in car. Think I have a noisy K line.

I assumed you tried all the baud rate/inits, this is a last resort pretty much. Title: Re: Trying to flash in car. Think I have a noisy K line. Post by: stuklr on April 05, 2014, 06:26:51 PM Well, flashed for the first time successfully. Ran 38kbps and it stopped twice, just clicked to reconnect and it continued where it left off. Never touched the key.
Think i will try even slower next time. |
