Looking for obd2 (On board Diagnostics)
 

Hi all, First time using this! I have my 2012 Jeep Cherokee Jet (Liberty in North America) and lots of warning lights flash on it when I do any 4x4 driving. I am looking for an obd2 reader than can show codes and can clear them as well. I have seen a few on ebay for a 200 to 300 hundred. Just want to make sure I am getting something that will do what I need.

Last time an autoelectrician cleared some 37 codes, and mostly nothing major.

Cheers, \

You dont have to pay that much if its just an engine scanner

As I have a '96, which have a weird OBD2 profile, I ordered this one

$40, (from USA) works with your mobile phone

I have 2. An eBay cheapie to link with the free version of Torque for getting readings, and a Bluedriver, which is ~$100US, that can scan & clear codes for all the computers*, not just the ECU. It also supplies diagnostic info on common causes of codes that users have reported back to them.

The Bluedriver was very useful when I was chasing ABS error codes as they wouldn't show on the dash display. Ended up being just a failed sensor.
The eBay cheapie + Torque helped to figure out that it was the cats failing not the sensors by looking at the O2 sensor outputs on a graph. (Because the Bluedriver module won't talk to Torque.)


*Most cars have at least 3 these days, ECU, ABS, Transmission...

BlueDriver best value

I use an EDS (Engine Data Scan) I bought from the 4WD Supercentre. They are usually around $80 (The prices fluctuate depending on what sale they are having at the time.

It will show and clear codes as well as display a heap of vehicle info when used as a gauge.

It's one of the best things I ever bought from them.
