hey gyys i have a 2009 freightliner with a dd15. it has 2 DTC codes on the dash on start up. they are CHS 71 and CAB 33.
also after 12 hours my primary tank has 0 PSI, yet my 2ndary tank has 110 PSI. this is with both trailer and without trailer. any ideas why that would lose that much air over 12 hours? while driving it is just fine
truck runs great other than these issues
