error message on odometer lcd

lately for now reason I get a no bu5 message on the odomoter.
I lose my rpms, speed, and other functions with the dash.
Then it will come back. Does it sporaically and no rhyme or reason.

THanks

This Is Basically Telling You That There Is A Short Somewhere In The Elctrical System. I Had The Same Problem On My 99 Tj, And I Ended Up Pulling The Entire Cluster Out, Only To Find That A Hair Had Gotten Into The Connectors Right Behind The Cluster, And I Had Grabbed Some Of The Connector Grease, And It Was Causing The Terminals To Cross. Remove The Hair. End Of Story. I Called The Dealer About This Problem First Though, And They Told Me It Would Be Around $200.00 To Look At It, And I Would Have To Leave The Tj There Probably About Three Days So They Can Check The Entire System....... ($200.00 To Remove A Hair!)
