I was hoping someone would ask the correct question...

But it's may seem like a foreign language to the uninitiated..and you also have to have the correct tools and know how.

I gotta get my hard copy notes as I'm at work and don't have my memory stick with all that sort of data for quick reference.

Give me a couple hrs.

Wish I could help but I've never used that tool.

Have a 2006 Commander with 65000 miles and had the recall done a few months ago and now am in the same boat as the rest of you. No 4-Low. The dealer that did the recall just lost their dealership and now I have to travel 70 miles to the next closet dealer to have this looked at. I opened a case and have a case number with Jeep. Any advice on this trip to the dealer to try and get this fixed and perhaps fixed without me having to shell out the $$?

Has anyone tried to get a magazine to investigate this issue and write a story about it? Perhaps some publicity will get Jeep to do something about this!

As of today Chrysler has 87 transfer case actuators in stock, and there are 1696 currently ordered. If the actuator is the fix, we are boned for some time to come.

But from the posts I have read it seems that the actuator is not really the fix either - since people who have had the actuator replaced still end up losing the 4-Low a short time later. There is no way on God's green earth that I am going to shell out darn near $1000.00 for a new actuator if that is not a guaranteed fix.

KWP 2000 is a Protocol not a tool. It's a "language" (like English ..if you want to call it that) that is used to communicate with the various modules (or Nodes) on the Can Bus.

protocol

noun (Concise Encyclopedia)
In computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it. Without a protocol, a transmitting computer, for example, could be sending its data in 8-bit packets while the receiving computer might expect the data in 16-bit packets. Protocols are established by international or industrywide organizations. Perhaps the most important computer protocol is OSI (Open Systems Interconnection), a set of guidelines for implementing networking communications between computers. The most important sets of Internet protocols are TCP/IP, HTTP, and FTP.





Think of the Can Bus as a land based telephone line....and for example two people are having a conversation on the telephone and both are speaking english.... so to define that conversation ....it is defined as... "The English language being spoken on a land telephone line that is understood by both parties at either end of the line."

The same telephone line doesn't care if English, French, or Spanish is being spoken and as long as both parties at each "end" of the line understand each other.

There are quite a few different protocols used on Can Buses.. I'm not going to go into that here that's what Google is for.

The models years affected use KWP 2000 the newer years 2011+ are Powernet and some state of the art buses are using UDS and Flexray .

Now tools are the telephone itself, it can be Star Mobile, WiTech, Star Scan, Snap On, OBD scanners of every sort.

Then there is the "ELM" as very low cost chip that can be programmed to do alot of things.. but you have to be very programmer savvy.

Just to show that sometimes it takes lots of data crunching to bust down the factory tool stuff .....to hack the Can Bus

What a load of tech nonsense all this because CC thinks you aren't smart enough to shift a damn shift lever. I was considering a WK II for my wife's next one but after this fiasco no way.
