Well I used the write-up on howtoECUcodes and when the sequence was complete only thing showing was the mileage. I'm assuming I had no codes. I about choked when I went searching for a DRB III. I see code readers for $49 and up on the web. What do I need more than the built-in diagnostic reader? My 2000 XJ is new to me and I'd like to verify no issues while all is well so when something happens I know what the baseline was. Thanks all.
Be SURE to get one that allows you to clear (erase) the codes. That is a very important function. Most of them I believe have this function except for the el-cheapos, which I'd stay away from. For a few bucks more, you can get one of the above brands.

I just wonder if we really need the DRBIII scan tool for our Cherokees DTC !!!!, will the OBDII code readers be enough to retrieve all codes?.
What can the DRBIII do that all other scan tool brands cannot do.
DRBIII scanner cannot be found for less than 2000 bucks.
OBD-II trouble code scanners will read the Check Engine Light trouble codes and enable you to erase the codes. Some trouble code readers will also read ABS brakes and some will also display live data from your engine sensors.
DRB-III diagnostic scan tools can reprogram your engine computer, as well as read codes and display live data.
