PROBLEM
The DEF line to the DEF injector needs to be replaced on certain 926M, 930M, and 938M Wheel Loaders. The existing DEF line routing can lead to DEF injector plugging that can lead to partial or full blockage of DEF flow.
The updated engine software provides improvements for BPV control, DEF level strategy, DEF quality sensor strategy, DEF injector strategy and SCR storage model, and ether injection quantity.
