INDICATORS
On Board Diagnostic System-OBD
On board Diagnostics or OBD is an
automotive term referring to a
vehicle’s self Diagnostic and
reporting capability. The OBD system
allows continuous diagnosis of the
components of the vehicle correlated
with emissions. This system warns
the driver, by turning “ON” the
Malfunction Indication lamp (MIL) on
the instrument cluster, when a fault
causes emission levels to increase.
The OBD system also has a
diagnostic connector that can be
interfaced with appropriate
diagnostic tools, which makes it
possible to read the fault codes
stored in the Electronic Control Unit,
together with a series of specific
parameters for Engine operation and
Diagnosis. This check can also be
carried out by the traffic police.
To access the diagnostic connector
(Fig. 1),
which is located below the
dashboard
(Fig. 2)
at the RH side of
the steering wheel as shown in the
below images.
NOTE :
In case the fault occurs and
MIL on the instrument cluster comes
ON, contact nearest

eliminating the inconvenience, to
check the system completely,
TATA

necessary, road tests which may also
call for a long journey. The
functioning of MIL lamp may also be
checked by the traffic police using
specific devices.
