I am seeing fault codes ecu 128 and numbers a 545 137 on my dash. Of my 2006 Freightliner Columbia 60 series 14L Detroit. Anyone know what's going on?
Check the engine manual. Google if if you have to. The codes have a specific meaning. See if you can find a manual for your engine online in a PDF format then the codes for faults should be contained in that manual from Detroit.
