    Finally solved the problem. There were 14 wires on ecm plug by plastic covering. When they assembled in factory did not put any other protection on wires like tape, just plastic pipe. Found corrosion on broken wires. Fixed by small shop in chicago. Its shame to freightliner dealer who could not find anything and just me charged money for doing nothing.
