Quick answers for managing Hitachi DPF/SCR DTCs
DPF/SCR DTCs are codes related to emissions systems, indicating faults in filters or catalysts.
Common causes include clogged filters, low DEF, or faulty sensors.
Use the HVI app or vehicle controls to initiate a manual regeneration.
DEF (Diesel Exhaust Fluid) reduces NOx emissions in the SCR system.
Check emissions systems daily or as per HVI's KPI recommendations.
