Malfunction

Indicator Lamp

A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the vehicle. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
Service Only Mode, as a check to
show it is working. If it does not,
have the vehicle serviced by your
dealer. See Power Button on
page 9-17 for more information.
If the malfunction indicator lamp
comes on, while the engine is in
ON/RUN, this indicates that the
OBD II system has detected a
problem and diagnosis and service
might be required.
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.
