OBD diagnostic tool

I am looking for a good OBD tool. I see some relatively cheap ones that plug in I'm guessing under the steering wheel and I get all kinds of info on my iPhone.

Suggestions?

exactly what are you wanting to do with the tool and how much are you willing to spend?

just check/clear the check engine light? pretty much any of them can pull and clear codes

get some live sensor data? quite a few options from the higher level consumer stuff to the pro stuff... also phone apps with a bluetooth/wifi/wired adapter

ABS codes? this is where things get tricky... many scanners say ABS but the fine print is "select makes/models" or "most domestic vehicles" i don't know enough about 01 XJs to say what scanners will or will not pull ABS codes i just know that sometimes a scanner will include a vehicle in a coverage chart but it actually won't work (ex. Actron CP9680 and a 97 ZJ)... the pro/dealership level stuff will do it but prices range from "not too horrible" (Snap-On MT2500) to "they wrote a Law & Order SVU episode about what happened to my wallet" (DRBIII)

ABS bleed? see pro/dealership level scanners

I'd like to see live information. O2 sensors, fuel pressure, Temp. I just want to get as much information as possible. I see some are $20 some are $100.

I don't know much about them.

I saw someone using one giving live O2 sensor readings, but it didn't say what devices was used.

Not very familiar with XJ specifically, but in general, you'll be a bit limited with the iphone. AFAIK, the iPhone is only compatible with wifi adapters (won't work with BT or USB adapters). And from what I have read, the wifi versions don't seem to work as well as the BT versions. Once you get an adapter, there are quite a few free, or very inexpensive programs to choose from to view the data, such as Torque for Android. A good program will allow you to make custom PIDs so you can monitor pretty much anything you need to. If you are stuck with the generic PIDs it won't be nearly as useful.

Actron has a good line of scan tools. Also, take a look at the INNOVA line of scan tools.

For not much more than a code reader, you can get a decent (but basic) scan tool that sounds like will meet your needs. I have the Innova 3040. Does a lot for under $100.

A search on Amazon for these scan tools will give you lots of options.

Without "data", all you have is an opinion!

I've got a harbor freight one that I'm surprisingly happy with, I think it was around $60-70

Starting my search too. Saw the innova 3040 and liek what I see as far as features but when it comes to describing "live data" none of them have much detail.

What "live data" would I be able to see? Does it vary from scan tool to scan tool or car to car?

I would like to see trans fluid temps prior to and post cooler (if sensor(s) exists), exhaust gas temps, oil temp (digital would be nice since the dummy gauge on the cluster is lacking imo), coolant temp (digital again), fuel pressure and maybe what is going with the four O2 sensors. I have knocked around the idea of more gauges on the A pillar but haven't found a nice gauge cluster surround to suit me.

I went ahead and picked up an Actron CP9670 yesterday from Advance. I used it to clear a code on the jeep and several evap canister codes on my sierra.

The Jeep doesn't support a whole lot of "live data." The gmc does.

I have a cheap Bluetooth ODBII adapter (From ebay) that I've used with the Torque app on an android phone for years now. Works great. It let's you build profiles for multiple vehicles and lets you build a "dashboard" of gauges to customize and monitor exactly the specific parameters that you want. The code reader is pretty basic, but it works and gives links to lookup further info about codes on the web. It won't do ABS, but for everything else, I've been very happy with it.

I bought a Kobra wireless one for $20. It spits out lots of info but I'm not sure how helpful it is yet. I'm mostly concentrating on O2 sensors. I'm not sure how accurate the readings are or if my O2 sensors are working correctly.

I'm using OBD Fusion for iPhone to read it.

The DRBIII is the best but hurts wallet, you can get your job done with any OBDII scanner though.

I have had a Linear Logic ScanGauge II in both my XJs and my WJ. Good live data, lists codes both stored and fresh. Wish it was better constructed and the cable wasn’t so finicky...
