"Passive" Regeneration and is transparent to the opera-
tion of the vehicle.
Occasionally, the exhaust gases are too cool for passive
regeneration. When this occurs, the ATS will regenerate
the DPF by increasing the exhaust temperature. This is
referred to as an "Automatic" Regeneration and is also
transparent to the operation of vehicle. An Automatic
Regeneration event typically lasts 30 minutes. During and
shortly after the event, the exhaust gases from the DPF
may reach temperatures in excess of 650 C (1200 F). See
the information in the table below on probable causes and
recommended actions related to the warning lights and
indicator symbols of the ATS.
The ATS may not be able to regenerate the DPF when the
vehicle is driven at extended low speeds or with frequent
start and stops. In such cases, warning lights and indica-
tor symbols will alert the operator to take action. The oper-
ator should be aware of whether the lights are on alone or
in combination with others. The following table will
describe each warning light(s) and what actions are
needed from the operator.
