DIESEL PARTICULATE FILTER
(DPF)
Your vehicle is equipped with a
Diesel Particulate Filter (DPF).
DPF is a mechanical filter that
physically traps particulate matter from
diesel engine exhaust gas.
DPF traps the particulate matter in the fol-
lowing way:
Filtration - Particulates / soot are col- •
lected in the inlet channel of the filter.
Regeneration - When the filter chan- •
nels are filled up with soot, they are
cleaned automatically by the engine
management system. This process is
known as DPF Regeneration and this
will happen during normal running of
the vehicle.
DPF equipped in vehicle normally regen-
erates automatically which is controlled by
engine management system.
In certain specific driving conditions, DPF
regeneration may not happen automati-
cally as the desired temperatures required
to regenerate soot may not be achievable
due to specific driving conditions. This in-
cludes prolonged driving at low vehicle
speeds for considerable amount of time
(driving in heavy city traffic), prolonged
running of the engine in idle conditions etc.
In such cases, a warning lamp as indi-
cated above will be illuminated in the in-
strument cluster indicating that soot
regeneration is insufficient.
This warning lamp switches ON constantly
to indicate that the DPF needs to be re-
generated. This lamp does not indicate
any malfunction.
The warning lamp remains OFF during
normal vehicle behavior and lights up only
when driving condition requires the driver
to be notified. When this lamp is ON, keep
the car running ideally at 3
rd
gear, 60km/hr
with engine speed over 2000 rpm until re-
generation is completed and warning lamp
goes OFF. The process normally takes
about 20 minutes.
If DPF regeneration process
requested above is not fol-
lowed for a long distance and
the vehicle is driven with warning lamp
ON, it can cause MIL to be turned ON.
Once MIL is ON, please contact nearest
TATA authorized service center.
Service should connect the TATA MO-
TORS diagnostic tool and conduct DPF
service regeneration as indicated in the di-
agnostic tool.
Insufficient DPF regeneration resulting in
the above lamps can also happen if the
vehicle is driven with adultered diesel.
NOTE
Do not shut down engine till the warning
lamp goes OFF.
