TT-15-025 Subject vehicles may exhibit a MIL lamp on with reduced engine power due to a fault within the SCR (Selective Catalytic Reduction) system. If DTC?s (Diagnostic Trouble Codes) related to the DEF (Diesel Exhaust Fluid) pump set, it will be helpful to follow the latest diagnostic troubleshooting procedures published in the 2015MY OR LATER online Workshop Manual found on Hinonet. Hino has found that the majority of DEF pumps returned through warranty function properly and did not require replacement. The DEF pump has a serviceable inlet connector (which has a filter screen), a serviceable backflow connector, and a serviceable DEF filter. Failure to follow the published diagnostic procedure may result in warranty chargeback, if the pump assembly is replaced when notrequired. Please review the diagnostic tips below regarding the DEF pump.

SB-15-031 Foreign debris in the DEF (Diesel Exhaust Fluid) tank may cause the SCR (Selective Catalyst Reduction) system to malfunction. This can result in DTC?s (Diagnostic Trouble Codes) P20E8 or P20E9 - DEF Pressure Abnormality. An inlet strainer for the DEF tank has been made available to prevent foreign material from entering the DEF tank.
