2009 DODGE NITRO bulb

27. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD, that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON position, before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
If the MIL flashes when the engine is running, serious
conditions may exist that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.28. Cruise Indicator — If Equipped
This indicator lights when the electronic speed control
system is turned on.
29. Odometer/Trip Odometer Reset Button
Press this button to change the display from odometer to
either of the two trip odometer settings. When the trip
odometer is displayed, press once for Trip A, and press
again for Trip B. If the instrument cluster is a base cluster
(no separate compass/temperature display), press the
button a third time for outside ambient temperature on
the odometer display. Press and hold the button for two
seconds to reset the trip odometer to 0 miles (0 km). The
odometer must be in trip mode to reset.
Press this button to view the compass display (if
equipped). Refer to “Compass/Trip Computer” in this
section.

366 MAINTAINING YOUR VEHICLE

Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4.
As soon as you turn your key to the ON position, you will
see the MIL symbol come on as part of a normal bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system isnot readyand you should
notproceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
isreadyand you can proceed to the I/M station.
If your OBD II system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
