INDICATORS & OBD DIAGNOSTIC SYSTEM
NOTICE
If the Service indicator lamp remains "ON" when the
engine is running, the engine's performance deteriorates
marginally & sometimes significantly. Take your car to a
TATA Motors Authorized Service Centre.
Malfunction Indication Lamp (MIL) :
This symbol comes 'ON' when the ignition is
turned "ON" and goes "OFF" once the engine
is cranked.
NOTICE
This symbol will remain "ON" for any engine related fault,
which may cause increase in emission levels of the car
beyond the regulatory limit. Take your car to a TATA
Authorized service centre.
On Board Diagnostic (OBD) 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.
The diagnostic connector is located below co-driver seat
as shown in the figure.

NOTICE
In case the fault occurs and MIL on the instrument cluster
comes ON, contact nearest TATA MOTORS authorized
service center. After eliminating the inconvenience, to
check the system completely, TATA MOTORS
authorized service centers 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.
