True, but not all OBD II readers have the ability to clear higher level DTCs. Obviously, if it is a failure, you can't clear it. The cheap units you can buy at Pep Boys can't clear much and if your vehicle uses CANBUS then you'll need a vehicle specific unit. I don;t believe the Jeep uses CANBUS.

So, it's possible that it just doesn't have the software to clear those codes.

Here's a higher level reader you could use, but I would save the Superchips unit as a tuner only device IMHO.

I have the i906 and its a great unit. It's Volvo specific and it's saved me hundreds of diagnostic dealer fees.

The i810 will work with Chrysler products.

Great, thanks! I'll check out those links.

I didn't see anyone bring up the Diablo Sport T1000. Currently the best programmer out there. It reads and clears codes as well as programs in tunes. It can also upload custom tunes.

Great addition, have you used this programmer?

I will add that this is for the 4.7 and 5.7 engines only.

I bought two, a used older model and a new one last year. I have been using the used programmer on the Commander and intended to use the new one on a 2004 Durango. Unfortunately, that year is the only year not supported.

I have used it to read and clear trouble codes and downloaded gas tunes into it. It has 3 levels of performance based on fuel octane and a fuel miser option. A custom tune can also be created and downloaded into the programmer. I have also used it to compensate for tire size and pressure.

Does anyone know if there's any problem with the Austrian made XKs and the SuperChips F5?
I've read some "bricking" comments on UK units, but there's nothing conclusive that I could find.

Thanks!

You might be better served calling superchips directly and asking.

This is not true.

Based on the pictures I'm posting and the experience I'm getting ready to share, I'd surmise that the option to adjust ANY settings related to the TPM sensors is not available on Jeep Commanders - and here is my reasoning:

According to the manual (pictured below) the TPM sensor settings are supposed to be in the "Tire Pressure" sub-menu under "Quick Options".

The manual goes on to say that "The availability of the following features depends on the year & model of your Jeep".



Now my F5 is basically brand new - received it a couple of weeks ago and I just updated it again yesterday and I don't even have a tire pressure sub-menu under Quick Options.

These are the only options I have available for my 2008 Commander under "Quick Options" - see the below photo:



The only conclusion I can come to, is that F5 (3874) Flashpaq does not give you access to the Tire Pressure sub-menu, which means you have no access to any TPM sensor settings on Jeep Commanders.

Now I have re-programmed my engine with the 93 Octane performance tune (which I'm quite happy with);
I've also cleared all the old Diagnostic Trouble Codes that were stored and I've successfully adjusted my speedometer by programming in my larger tire size, so it is a very useful tool.

If there is anybody else on this forum that knows something pertaining to this TPM sensor issue that we haven't touched on, by all means, please share whatever usable information you have.

Thanks in advance.
UPDATE:

So, after I downloaded & applied the latest software update to my Superchips Flashpaq F5 3874 using the "Ignition" program about 10 months ago, I finally have a "Tire Pressure" selection in my Quick Options Sub-Menu:




This is where you change the tire pressure setting that will set off the TPM sensors - that's the good news; The bad news is that the lowest you can take the Tire Pressure setting down to is 22 PSI; it's set at 28 PSI by default from the factory.

If it allowed you to take the tire pressure setting all the way down to 0 PSI, you could have essentially disabled the TPM Sensors which would have been great;

However since the lowest you can take the tire pressure down to is 22 PSI, it's not really very helpful in my opinion.

You can disable the TPM Sensor system using the AppCar-DiagFCA OBD-II Software
which you can read about here;

Wheels / Tires

TPMS issue

This software along with the proper ELM327 USB from Total Car Diagnostics is only about a $100.00 investment and well worth the money in my opinion as it is professional OBD-II diagnostic software, that gives you complete access to all of your XK's options and you can basically change, modify, enable or disable any feature your XK has; I highly recommend it.

I just updated mine after 2 years and I did see the tpms selection. I also selected the 93 tune, I had been using the 91 tune. I haven't driven it yet to see if there is a big difference between the two. Other than that I adjusted my tire size for the larger 20 inch wheels.

So, whats the verdict @srad2drag ?
