I was getting error codes that suggested rear wheel speed sensors were not working, and indeed on a drive up the driveway there was no rpm output showing. Weird both went bad.
This drove the transmission into limp mode with an error that transmission output speed was not matching wheel speed. Makes sense, but it’s crazy how connected these things are. I got new wheel speed sensors on it this afternoon (Amazon delivered today, might have been USPS) and I was getting good speed signals on all 4 wheels and they matched. Had the computer hooked up monitoring it all. Cleared all codes and went for a drive. Was doing well up to 35mph or so, trans shifted up to maybe into 3rd gear then went into limp mode again with same error about turbine output speed not matching wheel speed. Was getting a good transmission speed output too and all the other speeds inside were showing so I don't think it's a conductor plate fault. I'm thinking it has to be a software issue with the mismatch. I talked to my buddy Todd who had flashed the new conductor plate and actually reflashed the whole vehicle some weeks ago. I’m thinking something in the software is wonky such that the trans and wheel speeds are not specifically for this vehicle, or that it was corrupted somehow. He’s going to dial into it tomorrow and see what might be wrong. Maybe reflash it all again. I could feel the engine just wanting to run hard, this thing is incredibly powerful. Can’t wait to get this issue sorted and go ripping around in it. --FT Sent from iFōn _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
