Clearing codes on a 04 Rubicon??

Just disconect the battery for a half hour???

You're going to reset the PCM if you do that; all of your adaptives will have to be relearned by the PCM. Best bet is to find someone with an OBD II reader. Most auto parts stores have 'em to loan free at the store.

Most adaptives are relearned in 50 to 100 miles are they not? If that's the case, just reset that ho.

50 cold starts that warm up to operating temperature... IIRC

Yes, must see a change of 40 degrees or more operating temp. Regular drive cycles if it's warm already won't do it and it doesn't care how long the drive is.

Depending on the scanner the local parts shop uses, it may or may not be able to clear the codes. It's a free service though so definitely worth a look. Any dealer will have a computer in the shop that has ability to so if you know any maintenance guys at a dealer or maintenance shop, a few beers will likely do it for you. Real quick process, takes longer to plug it in and find the right screen than to clear the codes.

Best of Luck,

Mike

Cleared codes.

Let it sit for a couple of hours, cold.

Drove it 50 miles. Parked it for the night, hopefully that will do it or I'll just drive it over the weekend.

It costs like $20 to get a reader off Amazon so you can do it yourself. Sure you don't get full diagnostics with that, but absolutely reads and resets codes. A lot cheaper than the value of my time running around to auto parts stores or dealerships with beer.

Passed smog today...

Most adaptive learning is always relearning. The jeep will start relearning the fuel trims after 1-2 min after a cold start and then it will adjust the short term trims every second or 2. It will update the long term trims in 5-10 min. There is nothing bad that will happen if you unhook the battery. The idle will be a touch higher at first, but then it will calm down. The evap and other bs might take a week or to relearn / run all the tests and monitors, but that is just smog bs that doesn't affect how it drives.

If the code returns, disconnect both battery leads, touch them together and hold them together for about 15 seconds. This will completely discharge any capacitors that are powering any kind of memory. When you first touch them you should see a tiny arc. And yes, it takes 50-100 miles for re-learning.

I did this about a year ago and still haven't seen the P-2096 code again.
