Frank, the '97 can display its own diagnostic codes on the odometer display
by only turning the ignition key on-off-on three times within five seconds.
While there were a few years when the TJ could not do that, that ability was
brought back in later TJs.

You should really stick to subjects you have a clue about.

It's amusing that you accuse me of guessing, when you're the one doing all the
guessing...

You guess that because you 'own' a TJ this makes you some sort of 'expert'. Do
you 'own' an OBD II scan tool? I didn't think so...

You guess that just because you've never seen a 'P' code, yours doesn't 'use'
them.

You guess that because you can turn your key off and on just right, and you can
count the check engine light flashes, those are the only codes that exist.

Wrong again...

A couple of facts for you:

If you can figure out how to get your hood open, take a look at the emissions
information label. You'll see that your '97 TJ is OBD II Certified. In order
to be OBD II certified, among other things, it must store OBD II compliant
Diagnostic trouble codes, and they must be able to be read using an OBD II
compliant scan tool. In case this is still over your head, that means that the
DTCs take the 'Pxxxx' form.

Yes, your TJ does store 'P' codes.

I figured you'd be here soon. Nobody is as proud to show off their ignorance as
you are.

Now run along and do something useful. I haven't seen the charter in a while,
why don't you go post it.

Damn, you need to go look at a '97 TJ before you post stuff you don't have
direct experience with. The '97 TJ displays the diagnostic codes I already
gave you the link to directly in the odometer, you don't count the flashes.
If you bothered to READ the data on the link I gave earlier, you would see
the codes that the '97 TJ gives DIRECTLY on its odometer. Even though the
flashes also correspond to the numeric codes given in the odometer.

Did you even fawking bother to go to the link I gave earlier to see the
codes? Or did you ignore them because they don't agree with your claim?
