INDICATORS
ID Indicator Name Description
1
Diesel
Particulate
Filter
(DPF)
The exhaust diesel particulate filter (DPF) has excessive soot levels and requires passive
or active regeneration (regen) to burn off the soot to prevent a clogged filter.
Passive regeneration occurs when the vehicle is driven at a challenging duty cycle, such
as highway driving for at least 20 minutes, to increase exhaust temperatures.
Active regeneration supplements soot burn-off by injecting diesel fuel to increase
exhaust temperature.

combustible surface or material.
