Hi, I also have MD802 and also need to scan a 1999 Jeep Wrangler for airbag codes.

Just following up on my own inquiry. Tonight I tried to use the Chrysler CCD adapter from DS708 again with my MD802.

   Based upon what you wrote Max, I spent $100 having one of these Chrysler CCD adapters for the DS708 shipped to me in Canada from China. It does not work at all. I still get that "can't connect" message. It is as if it isn't even there. I still cannot access my ABS module and clear the code that I originally bought the tool for. I am disgusted with AUTEl. It is fraudulent for them to say that this "all systems" tool is "one tool for everything" when the first thing you find out when you try to use it is that you need to buy another tool (side slipped by calling it an adapter) for $100. I phoned Autel tech support about this and they are rude and useless. They had me reload all of the firmware on the tool and told me that I was an idiot because I followed the instructions and installed the software using the cd supplied with the unit. (He told me that I should have ignored the instruction manual and just downloaded directly from this site). I've wasted many hours trying to get this unit to connect to my ABS on my 1997 Dodge Van and I have concluded based upon my research, experience with this unit, and Autels tech support that I never had a chance because it is all a lie that it supports what they claim it does. I have serious doubts now that this unit does even a fraction of what they say it does and so I am returning it as fraudulently sold to me.

Hey Jon,
sorry to hear that your Scan did not work out.
So here are couple of things for you:
1. this is the cable that I use with my MD802 and CCD adapter from DS708
http://www.aliexpress.com/store/product/Replacement-Red-Main-Test-Data-Cable-for-Autel-MD801-MD802-Scanner-OBD2-15-pin-to-15/713479_32250081096.html
It is imperative to use the correct cable, because of the required wiring.
Which cable did you use? I hope not some generic 15pin male to 15pin male cable.

2. the fact that the scanner can not read native modules via obd2 port on older vehicles is because of the way car manufacturers implemented native car communications. Initially OBD2 port was standardized for generic obd2 messages only. Newer cars are much more communication's friendly and pass all the info via OBD2 port, including native modules (SRS, ABS, etc...).
No scanner is perfect, but I have had good luck with MD802. It supported all the vehicles I have thrown at it, and that was about 50 different brands/makes and models.

3. Unfortunately autel support is lacking in knowledge or distribution of that knowledge, because I have had to learn a lot of these things the hard way.

 I recently purchased the MD802 and have the same Chrysler issue. I bought a Chrysler 16 on ebay and was going to buy the cable from your link when I noticed an issue. The cable you linked is Male to Male. The Chrysler 16 adapter is female however the connector on my MD802 is Male. With this a Male to Male cable would not work. I instead purchased an Autel Male to Female red data cable. Hoping this will connect to my 1999 Neon like my mechanic's Snap-On tool can.

 It did not work even with the Chrysler 16. Tried both the black and red version of the Chrysler adapter and neither worked. Sending this thing back to Amazon.
