PROBLEM
Certain 0R-9841 Remanufcatured 3508B engines used to repower 777D trucks were shipped with the incorrect engine software. Fifty-five Remanufactured engines were shipped with 306-4183 Software and need the engine Electronic Control Module (ECM) to be flashed with 306-4153 Software. The performance differences between the two software files are neglible. The software needs to be updated in these engines to make them compatible with the production engines in terms of performance and emissions, and the need to maintain product quality and operation.
