We only get one code guys... and thanks for the replies. (How ya been Hawgflash?)
U1016 Loss of ICM/ECM Serial Data Instruments
U1016 Loss of ECM Serial Data, Vehicle Speed, Vehicle Inhibit Motion or Power train Security Status TSM/TSSM
We've cleared history but it comes back when our gremlin does.
This is what lead us to replace the VSS... was the first thing we did. No joy, Replace the speedo with a spare... nope. It is also what directed the HD to give him an new ECM.
We never got the dreaded P0605
We did, however, had to open up the ECM connector to add the ACR wire. We haven't revisited the inside yet because the ARC's are working fine, but will. It's great that you guys are pounding on bad connection. Although we've been over the bike from stem to stern this seems to be everyone's advice. We're frustrated and this really helps.
Give me a few days and I'll open the ECM connector back up to see if there's a loose or touching connection. Won't take long.
