    Working on a 2000 WS flashing a code 55 all the time.tried clearing code as soon as you start the truck it continues to flash.changed both cruise switches still the same thing.any thoughts.also have a question as far as cummins isc caps pumps.getting codes 328 and 329,changed the lift pump and filters.insite basic won't allow me to do a click test on the solenoids on top for accumulator pressure.is the accumulator module a common failure
