Thanks for that info/link and will read up on that. Understand now that post of "complete reset" wasn't meant as a total EPROM(s) memory clearing.

Thanks again for the link. Mine came in today's mail. It's fine piece of electrical equipment and well worth the bucks.

I've used the shit out of mine and everyone in my shop comes for it and no sign of wear or any problems with it at all. I would also check out a site called probemaster for some leads with the right size banana plug on them. Another great site with good leads and what have you. Not sure if the whole name is a joke or what. I remember my wife coming into the room with a funny look on her face after checking e mails asking " Did you just order something from a company called ProbeMaster?" Guess you had to be there. But just to add to the funny ass name, it appears the president of the company is called Dick Push. All that being said I really like there extendable backprobe leads for my Fluke meter.

I'm looking forward to doing this. Just curious about how I will identify every directional cammand from the T4 to the vehicle. Will the recording device number each event and then I will make notes about what every command is? If I have access to a P38 there is a bunch of air suspension prompts like put it into diagnostic mode with prompts a double beep that sounds like a miss-lock. Inflate and deflate system. A whole calibration routine and other stuff I probably forget right now. Then with the GEMS and Bosch Disco's there are some other prompts that might be useful as well. I could just go thru the whole menue of commands and you pick out what you want. Relearn security immobilization would probably be a good one also.
This thing will be quick and basic. 12v+, 12v- and then whatever lines you are monitoring, K and L for the ecm. It's mostly put together, just need to program it and make sure it works.
it'll dump raw data to an SD card that is incrementally #'d. if you could rename the files to identify what you did during each recording session that would be helpful. You'll have to pull the card and rename it on a PC.
Once the files are there we can figure out baud rate and such. I know some other manufacturers increase the communication rate between the scan tool and ecm during dealer type stuff, I don't know if GEMS does that or not.
There is a lot to do. The recording is just part of it.

I have always thought that the T4 changes the baud rate depending on what it's interfacing with. Like the Disco2 was the first Rover that brought the CAN network to the diagnostic connector. But before that the stuff had to be very adaptive on the scan tool. Like for Freelander you have to switch between a grey conector and the Blue connector. They had what we called a switchable brick to make that transition faster. Then the black connector came out and that was supposed to cover everything. But not the Freeloader. You guys let me know what your most interested in and I will do my end.
What would also have been nice; the moron who coded the ECM should have given it the ability to determine when the fault was corrected.
Yes, this will. ECU and Transmission. At least on my D2.

I'll do a review for it in a few days. Still playing with it.
Don't assume that because it can do a Bosch system it will do the Gems units. I know nothing about the tool but the two vehicles are so different that I would look into it.
$185.
And I believe Discostew is right, it appears your truck is to old and dilapidated for this to access. Shoulda got a D2.
