Fellow Forum Members and Tireless Rover Owners,
I have been hard at work for the past few months, diving into the communications systems on the 2003-2005 MKIII Range Rover. Since I purchased my 2003 Range Rover, I have already had several major problems with the different systems. So I put hundreds of hours researching and investigating the different sommunications protocols in the 2003-2005 Range Rover.

I have had made a tremendous ammount of positive progress. I have been able to work through the MKIII Range Rover EAS system communications protocol. I have incorporated the MKIII Range Rover EAS communications protocol into a self contained hand-held device called the "EAS Activate MKIII". The EAS Activate MKIII will read and clear the stored EAS fault codes.

I will continue to work towards getting a comphrensive software kit for the MKIII Range Rover. Please feel free to send me your stories about your troubles and or systems in the vehicle that have given you trouble. I will get to work finding soluions as quickly as possible.

Congratulations!

I just wanted to be the first to Thank you on behalf of all RR owners who have benefitted from your R&D over the years.

Cheers mate :thumb:

Brilliant indeed..

Now for the big question everyone is afraid to ask...

Will you be writing a software packge like you did for the P38 for us to use via PC, if so it would be great.

Excellent Idea.
Short answer yes.
The plan in the next few months is to have a new piece of hardware released. This hardware will allow any windows PC with a USB port, to communicate with several Land Rover vehicles. Once the hardware is released, I will also release the software that I have written. The software will be free and allow the user to read and reset the faults on almost all computer subsystems on the P38a, Disco2, and MKIII Land Rovers.I will also make the software open source so that the software will continue to be developed after I am too tired to develop any further.

I think we should all pitch in and get this man a cape and the shirt with the big S will be ok on him to. Thanks Storey. :clap:

Wow, I was just about to give up on the possibility of something like this existing in the near future. If you read other threads in this forum you may note that I was attempting to seek information about just such a project. Has it been expensive to develop thus far (aside from sheer man hours involved)? I had personally just about given up because I decided I probably wouldn't be able to do it without a "real" dealer system to reverse engineer and I couldn't justify that cost.

I recently had my EAS compressor replaced. Before making the purchase, I did quite a lot of research about how the EAS performed. I've watched the videos on youtube to check if the sensors were faulty. It helped a lot! I'm really into cars and how their electronic systems work. I have always wanted to interface to OBD-II systems but was always worried about messing up the car and paying a ton to get it fixed. This thread has made me think twice about it. Thanks again Mr. Wilson!

I'm another one to give you much respect and thanks for making this product Mr. Wilson :thumb: I purchased and finally received my EAS Activate for the Mark III today and it worked like charm! :dance: It sure will relieve me of constantly having to go to my local independent garage to clear faults in the EAS, much less having to put up with the ineptitude of the dealer, and I can imagine that it will be a life saver from me going out if my mind if I encounter any EAS fault on the road. I have recently been having an intermittent 'reservoir tank static while filling' fault and still trying to figure out where this fault is coming from. I am already on my second compressor and hesitant to replace the reservoir tank because the one on my Range still looks clean and when tested appears to have no leaks. Buying a new unit just to replace the pressure valve is expensive. I look forward to new products that you may come up with to diagnose and set up the L322 Range Rover :clap:

I am a happy owner of your product. Well done! It works as you say it would!! A++++++++++++++++++++++++

Thanks!

Indeed. I have one as well. Plan to keep it in the vehicle in case of unplanned problems. Thought about a hawkeye, but it costs so much more. Maybe I'll eventually get one of those too... but since there is so much stuff that can disable the EAS, and it is so easy to repair... this little device is just what I want.

Got mine this week! Worked as described. Had one small issue as my laptop would not recognize the device. I used another usb cable on a different computer and voila - let me know what it found:

1.--Current Faults----->
Too Much Enegergy For regulation needed rear right
Faluts Cleared
<-END Faults

I beleive my issue is caused by a small amount of moisture in the system which freezes when the temp drops to BRUTAL. Cleared the code and no more issues.

when are you estimating this to be released? i am interested in buying the new piece of hardware!

Has anyone tried installing the latest software into the EAS ECU ? The original software was flawed and often resulted in the pressure static while filling fault.

Where did you get this information allyv8? Is there a TSB for this flaw? A few years ago, as a precautionary measure, I upgraded one of the EAS ECU which is located underneath the front passenger seat because Land Rover issued an advisory concerning early production ECUs that could be damaged when reconnecting the battery or by heat. I would have to look through my files to find this particular advisory. I am assuming my problem is simply that the valve connected to the reservoir tank get stuck sometimes, whether it be because of moisture, etc., and this triggers the fault, or worse, the pump beginning to fail :cry: The systems on the L322 is sensitive to declare a fault but Land Rover didn't program them in such a way that it would clear certain faults when it is no longer present upon restart of the vehicle :x In fact, after over a month, I had the same fault happen during a weekend trip out of town. Thank goodness for this reset tool! I saw what the fault was and it was cleared up right away :dance: Peace of mind! :pray: I will be waiting for new products from you Mr. Wilson :thumb:

There was a service campaign in 2003/2004 which made some updates... you should be able to check with RR to see if your vehicle was serviced. They should have a computerized record for dealer visits. It is a good idea to drain the reservoir tank periodically and check the air drier to prevent excessive corrosion from moisture. The air drier is a separate part which isn't terribly expensive compared with a new reservoir/valve block/compressor. It is worth checking.

Dan,
As a devout fan of yours, I have a question.
Will you(or possibly Rishi) develop this for Windows Pocket PC?
It would be a great compact tool to be able to carry around and make adjustments and such.
I'm lucky in that I have have the Unlock on 2 of my Pocket PC's and keep one in the RR at all times.
A lot more convenient than lugging the laptop around.

The possibility of this being adapted to a pocket PC or a more moden Windows Mobile platform, depends on the driver package for the USB bridge chip that I am using. The software will without a doubt require a piece of hardware. This is a requirement because of the different physical protocols in the Range Rover systems. This hardware will require a driver. So it is a possibility but to be honest. It is a long shot with a longer time line. It will be difficult enough getting evertyhing to work on the windows platform.

Java support may be possible (which may work on some smartphones or other OS)... but I have no idea what chip you are using... it is really the protocol which needs to be implemented I assume, since USB serial is a standard interface. I haven't personally been able to find a chipset that looks suitable. Everything I can find looks slow/outdated, but I haven't really played with vehicle diagnostics a lot so maybe my expectations are too high. I am very exited to see what you come up with and whatever chip you end up using, releasing code open source may allow others to build support for other platforms (if the chip "drivers" are closed source that could complicate matters, but at least having something the works on *some* platform would be a huge step).

There are a number useful of projects I've found (UniDiag for example) but I haven't been able to reliably pin down (no pun intended) what hardware interface I would need in order to be able to talk to all the RR systems (information is sporadic and rather limited) , things like the ELM327 seem to be specialized wrappers of sorts which don't expose the "raw" interface and therefore probably wouldn't work (at least not with RR).
