Malfunction

Indicator Lamp

A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
ON/RUN for key access or Service
Only Mode for Keyless Access, as a
check to show it is working. If it
does not, have the vehicle serviced
by your dealer. See Ignition
Positions (Keyless Access) on
page 9-14 or Ignition Positions (Key
Access) on page 9-16.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that the OBD

required.
With a diesel engine, this light may
also come on when the OBD II
system has detected a problem with
the Diesel Exhaust Fluid (DEF)
management system. See Diesel
Exhaust Fluid on page 9-27.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the dealer technician in
correctly diagnosing any
malfunction.

with this light on, the emission
