Back in Aug I had a question about a BUS ER that came up on my odometer. It just happens when my 08 Ultra sits out all day in hot weather or stuck in slow traffic . Tac & odometer needles bounce around dash lights flicker off & on. Doesnt hurt performance & only does it for 4 - 5 miles or so then goes to normal. Put about 100 miles on it this year in the cold & all is ok. When this first started had some codes P1010, U1064, U1097, U1300,U1016,U1301. Cleared them & they never came back. Anyway took it to a dealer last week & they couldnt find anything wrong. Irritating but I guess I will just have to ride it. Any ideas

 

Here is what your codes were: P1010 Missing Password EFI. U1064 Loss of TSM/TSSM Serial Data Instruments. U1016 Loss of ICM/ECM Serial Data Instruments, U1016 Loss of ECM Serial Data, Vehicle Speed, Vehicle Inhibit Motion or Powertrain Security Status TSM/TSSM. U1097 Loss of Speedometer Serial data TSM/TSSM. U1300 Serial Data Low EFI, U1300 Serial Data Low Instruments, U1300 Serial Data Low TSM/TSSM.U1301 Serial Data Open/High EFI, U1301 Serial Data Open/High Instruments, U1301 Serial Data Open/High TSM/TSSM.

I would suggest checking your Power/Ground Connections, TEST Battery and check Voltage Regulator/Stator Output, check ECM Connection, check TB Connection, check Connections at the Instruments and check Connection at the Speed sensor.

I've seen this as a Master Auto Tech a lot of times, in most cases it is either the battery or the connections at the battery, if the ECM is not getting the proper voltage it can mess with a lot of things.

 

...ad if you have a piggyback tuner, unplug it and replug to clean connections.

me thinks the heat of the sun on the seat is overheating the ecm...

would you use dilectic grease on connections

 

Yes I would.
