In certain specific driving
conditions, DPF regenera-
tion may not happen auto-
matically as the desired temperatures
required to regenerate soot may not be
achievable due to specific driving condi-
tions. This includes prolonged driving at
low vehicle speeds for considerable
amount of time (driving in heavy city traf-
fic), prolonged running of the engine in
idle conditions etc. In such cases, a
warning lamp as indicated above will be
illuminated in the instrument cluster in-
dicating that soot regeneration is insuffi-
cient.
This warning lamp switches ON con-
stantly to indicate that the DPF needs to
be regenerated. This lamp does not indi-
cate 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,
60
km/hr with engine speed over
2000
rpm until regeneration is com-
pleted and warning lamp goes OFF. The
process normally takes about 20
minutes.
NOTE
Do not shut down engine till the
warning lamp goes OFF.
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 TML diag-
nostic tool and conduct DPF service re-
generation as indicated in the diagnos-
tic tool.
Insufficient DPF regeneration resulting
in the above lamps can also happen if
the vehicle is driven with adultered die-
sel.
