Hacking your PCI Data Bus

Looking for something entirely different, came across this. Kind of interesting so thought I'd share.

This is way over my head, but very cool.

If someone can get my factory key fob to be used at remote start, that would be great. I am not sure I have enough time to learn what all can be done by this.

I understand some of it, but it looks like it can open up a lot of possibilities.

I read through it quickly yesterday but need to take a second glance at it. I have a little bit of a handle on this thanks to my background - computer programmer by day, college instructor by night (teaching computer use and hardware). I also happen to have everything I need to try it out. If I get a little time this weekend, which could be a little difficult with the new baby and all, I'll look into it.

Being that website is theksmith.com, I assume that's the same 'theksmith' here on JeepForum. He has an amazing build for those interested: My build - Expedition Rig - 2003 WJ 4.7 HO. He's also an Administrator over on OffroadPassport. His build thread there is TheKSmith's 2003 Jeep Grand Cherokee WJ Limited 4.7 H.O. - The Do-It-All Rig, which I imagine is quite similar to the one here. He has a lot of cool ideas in his build, many of which are unique compared to the common upgrades people do. With that said, I imagine if you ask nicely, he will probably be glad to chime in!

that is indeed me - thanks for letting me know about this thread, and for the kind words about my build!

if anyone is messing around with the PCI bus, feel free to ask questions here and i'll respond if i can help. i honestly didn't get far with reverse-engineering the wealth of proprietary Chrylser bus msgs... once i had what i needed for my tablet install i moved on to other projects. i did observe the msgs to unlock one or all doors, roll down windows, etc - so there are lots of possibilites.

the whole impetus for the articles was my project to have my Android tablet as a complete head-unit replacement, which has it's own build thread on mp3car: http://www.mp3car.com/worklogs/15515...rokee-4x4.html

pretty geeky **** for sure!

within the realm of possibility, but a lot would need to still be figured out to make it work.

the companies that make aftermarket remote-start systems have already spent the time to figure how to interface with the system, so probably attaching one of those and then observing what exactly it does would be the quickest way to determine the exact msgs that need to be sent to start the Jeep safely and bypass the SKIM module, etc. of course if you bought an aftermarket unit then you wouldn't need to develop your own, so catch-22.


several car makers, including even Ford are now actually pushing more open standards for interfacing with vehicles. Chrysler unfortunately is not one of them and instead are notoriously tight-lipped about that sort of proprietary info

I loved the Audi that I used to have. You could roll up the windows or roll them down with the key fob. Also you could do the same with the key in the drivers door, holding one way rolled the windows down and the other rolled them up. The whole passenger mirror rotating down when in reverse that made parallel parking easier.

Do you think all of this is a possibility with the hacking?
