Also i found a short cut, instead of disconnecting all battery cables, removing three CSCU fuses (two 25 amp and one 5 amp) for 5 minutes or so fixed it! Not sure why this problem happened ?
Thank you this site saved me a trip to the stealership!

I've gotten that occasionally in two different PB's. Always after starting the engine. It was always corrected by cycling the key off and back on again (when stopped). Something in the cab controller/ecm. Maybe yours is related to that somehow.
