To perform a DPF off procedure on any HINO trucks after remapping (sometimes even before), it is necessary to carry out a DPF reset function using the HINO DX2 software. This software is a Windows application that operates via J2534 and is highly stable when used with the NEXIQ USB Link 2 or 3.
The DPF reset function involves several steps to ensure proper functioning and accurate results. Here is a breakdown of the process:
1. Clear DTC Function “Delete All”: This function should be executed when there are no Diagnostic Trouble Codes (DTCs) present. It helps to start with a clean slate.
2. Check Inspection Menu: In the inspection menu, select “Start Inspection.” Then, perform the “Reset all DPR items” operation. This step is crucial to ensure that the Diesel Particulate Filter (DPF) is properly reset. Additionally, verify that the “DPR abnormal overheat flag” is set to ON. Finally, complete the inspection by selecting “End Inspection.”
3. System Protection Data: In this step, you need to verify the status of flags and perform a “Reset” using the designated button. This helps to ensure that the system protection data is properly reset. Confirm that the current value is set to OFF.
4. Recheck Result in Inspection: After performing the previous steps, it is essential to perform another inspection to validate the changes made. This will ensure that the DPF reset function was successful.
In summary, after remapping (and sometimes before), it is essential to use the HINO DX2 software to execute a DPF reset function. This process involves multiple steps to ensure proper functioning and accurate results. The software operates as a Windows application and is compatible with J2534, providing stability when paired with the NEXIQ USB LINK 2 or 3.
