Mine started this last trip out also, so I reached in behind the cluster & wiggled, pushed & pulled on the wires & the communication error went away . Today I removed the guage assembly & started the sled, started moving the wires & it went into communication error again, moved the plug some more & it went away. Dealer tells me that the asembly must be hooped. They are bringing in a new one which we will match up by flashing it & see if the problem continues. In the mean time I am off to the BIS...hopefully it continues to work...
