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 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. If you crank or start the engine, you

will have to start this test over.

3. As soon as you turn your key to the ON position, you

will see your MIL symbol come on as part of a normal

bulb check.

4. Approximately 15 seconds later, one of two things will

happen:

a. The MIL light will blink for approximately 5 sec-

onds and then remain on until the first engine crank or

the key is turned off. This means that your vehicle’s

OBD system is not ready and you should not proceed

to the I/M station.

b. The MILlight will remain fully illuminated until the

first engine crank or the key is turned off. This means

that your vehicle’s OBD system is ready and you can

proceed to the I/M station.

If your OBD system is not ready you should see your

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 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 system is

ready or not ready, if the MIL symbol is illuminated

during normal vehicle operation, you should have your

vehicle serviced before going to the I/M station. The I/M

station canfail yourvehicle becausethe MILsymbol ison

with the engine running.
