THE BREAK AIR PRESSURE CAN BE DEPLETED (RESULTING IN LOW OR 0 PSI) AFTER THE AIR SYSTEM HAS BEEN SERVICED OR THE VEHICLE HAS BEEN STORED FOR A LONG PERIOD OF TIME. IF DTC P0027 CONTINUES TO SET EVEN THOUGH THER ARE NO AIR SYSTEM LEAKS THAT MAY BE QUICKLY DEPLETING THE AIR SUPPLY OR CAUSING DELAYS IN THE BUILDUP OF AIR PRESSURE AND THE EXHAUST BRAKE IS FUNCTIONING PROPERLY, FOLLOW THE SERVICE PROCEDURE IN THIS BULLETIN TO REROUTE AIR DRYER LINES FOR IMPROVED AIR SUPPORT TO THE EXHAUST BRAKE.
