james from jeepersandcreepers.com showed us his new gadget at a norcal meet n' greet today - a palm pilot diagnostic code reader for tj's. it was pretty cool - it's software you laod to your palmpilot and it'll read all your engine codes! it costs like $199 (palmpilot not included)

I think its meant to interpret the engine codes not tell you the numbers. But then again I may be wrong

Me too.

Codes are no big deal just call the dealer and ask them "What does 12 24 and 55 mean?"

Trust me, they will say 12 is normal
24 means you fried another TPS

And 55 means end of codes. <IMG SRC="smilies/biggrin.gif" border="0">
My dealer calls me and asks me what the codes are. <IMG SRC="smilies/biggrin.gif" border="0">

Everybody seems to forget that the codes are just a guideline to help you fix a problem. There is soooo much more data in a JTEC controller beyond dtc's. There are freeze frames which tell you the exact condition when the fault occured. There is your short and long term adaptives, to allow you to see the fuel corrections at different "cells". There are "trip faults" stored for intermittent problems. It takes 2 trip faults to set a dtc. There is the basic mis-fire counters on all obd2 diagnostics. There is a function called enumerator factor, which lets you know if the pcm has learned the tone notches on the flywheel. There is your sync signal, which allows you to see if the cam angle sensor is in sync with the crank. All auto tranny functions, cruise functions, a/c operations, anti-theft, battery temp. and alternator diagnostics. The list goes on and on. There is no subtitute for a good scanner!

You sound like a salesman. <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/fj.gif" border="0">

Not a salesman, just a wrench. I see by your sig that you changed 11 tps's. There is a tsb for a re-flash that prevents false dtc's for tps's. Chryslers drb 3 scanner hooked up to their mds2 would have allowed you to look up flow charts that could have diagnosed and re-flashed the pcm to a newer part number. This would allow a larger window for the tps voltage, and stop the check engine light for tps. Sometimes it is not hardware, but software.
