On Board
Diagnostic
System
(OBD}
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL)
¢..ifl
in the
instrument cluster is part of the On-Board Diag-
nostic (OBD II) system.
The warning/indicator
light illuminates when the
ignit ion is switched on and goes out after the en-
gine starts and the idle has stabilized. This indi-
cates that the MIL is working properly.
If the light does not go out after the eng ine is
started, or illuminates while you are dr iving, a
28
malfunction may exist in the engine system. If
the light illum inates , the catalytic converter
could be damaged.
Continue driving with reduced power (avoiding
sustained high speeds and/or rapid accelerations)
and have the condition corrected. Contact your
authorized Aud i dea ler.
If the ligh t illuminates, the e lectronic speed lim-
iter may also be ma lfunctioning . For more infor-
mation ¢ page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig. 16 Locat ion of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as-
signed a code . In case of a malfunct ion, the com-
ponent will be identified and the fault stored as a
code in the control module memory .
The MIL light may also illuminate if there is a
leak in the on -board f uel vapor recove ry system.
If the light illuminates after a refuelling, stop the
vehicle and make sure the fuel filler cap is prop-
erly closed
