code reader

Thinking of buying a code reader. Never used one. I see WalMart has them. I dont want to spend a lot. Maybe around $100. I've heard some models can tell you gas mileage and such......

Any advice before buying one??

You want something beyond the WJ already being able to give you the codes for free?

Getting codes, as mentioned above, is free on the WJ.
Turn key to on-off, on-off, on and watch your odometer display the codes.
If you want something that will give you real time data, youre going to spend more than 100 bucks.
The el-cheapos from wally world will just give you a code read-out and possible even the source/problem of the code.
Check your local auto parts store for a scanner that gives you live data read-outs.

Don't! Unless of course you wanna pay out all your Christmas bonus on one. There's something that Chrysler/Jeep put in that doesn't allow a scanner to communicate to OBDII on the WJ vehicles. I've got two - a cheapie and an expensive one and both come up "No Codes" despite there being some displayed on the dashboard display. You can't erase them either. So in short a waste of space and $$ IMHO. Best get a friend that works with a dealer or the dealer to remove them....

If you have an export model, which I am sure you do, the VIN sequences are somewhat different and the scanners dont always recognize them.
I have used many over the counter scanners that work as advertised.

If you have an iPhone or Android phone, you can buy Torque for $5, the OBDII WIFI dongle for $150 or OBDII Bluetooth dongle for $100 (there are MUCH cheaper China made ones for like $30 that some seem to have luck with), and a $5 window suction cup to hold your phone. Just around $100 get's you a code reader, real time data, and allows you to erase codes.

Edit: I have one for my WJ and it works well. My mom also has one for her Isuzu Trooper and again, it works as it should.
