    Cummins doesnt use 6 digit fault codes. There is no such thing as that component description on the engine.

    What truck is this in?

    The only engine that has a Brake Saver hydraulic retarder is CAT. Has anybody been in, messing with parameters or done any updates recently? Kinda strange for a code to come up (most likely) related to a CAT engine. Makes me suspect this is a chassis issue and not a Cummins problem.
