Florida Pumper Posted April 17, 2022 Share Posted April 17, 2022 1999 mr. warning buzzer go’s off then truck dies. Will start right back up. Usually happens when I’m out ok cab as it is a concrete pump and operated remotely. Did have buzzy go off on way hame Friday and raised rpm’s up and it went off. Tried to hold set button for cruise to get code but didn’t give one. Only happens at low rpm’s long as I don’t idea it down to far runs all day. Also hooked cheap scanner up and didn’t show any codes. May not give a code while pumps are engaged because control panel for pumps utilizes cruise control circuit for throttle.
