AN OVERVIEW
ON BOARD DIAGNOSTICS SYSTEM
ON BOARD DIAGNOSTICS SYSTEM:
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.
NOTE
In case the fault occurs and MIL
on the instrument cluster comes
ON, contact nearest
TATA
MOTORS Authorized Workshop.
After eliminating the
inconvenience, to check the
system completely,
TATA MOTORS
Authorized Workshop are obliged
to run a bench test and if
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.
The diagnostic connector is located
below the dashboard at the RH side
of the steering wheel as shown in
the above images.
