GETTING TO KNOW YOUR INSTRUMENT PANEL

NOTE:
If you crank or start the engine, you will have to start this test
over.
2. As soon as you cycle the ignition switch to the ON posi
-
tion, you will see the “Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will
happen:
• The MIL will flash for about 10 seconds and then return
to being fully illuminated until you turn OFF the igni
-
tion or start the engine. This means that your vehicle's
OBD II system is
not ready
and you should
not
proceed
to the I/M station.
• The MIL will not flash at all and will remain fully illu
-
minated until you place the ignition in the off position
or start the engine. This means that your vehicle's OBD
II system is
ready
and you can proceed to the I/M
station.
If your OBD II system is
not ready,
you should see an autho
-
rized 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
.
Regardless of whether your vehicle's OBD II system is ready
or not, if the MIL is illuminated during normal vehicle oper
-
ation you should have your vehicle serviced before going to
the I/M station. The I/M station can fail your vehicle
because the MIL is on with the engine running.
