Re: Dedicated diagnostic software?
Your going to need to contact Witech... Witech is a wireless VCI pod that plugs into your DLC and then the software is loaded onto a computer. I read a disclamer posted by ebay about witech sales a year or so ago that Witech was deactivating VCI pods after being sold. I cannot remember all the detals but it was pretty crappy, something like the company wanted to double dip and be paid by the second owner too. Dont quote me though, im sure some poking around on ebay you could find the same disclamer. If you make some phone calls I am sure they would be able to set you up. If you own a 2010 or older grand cherokee a starscan will work just fine. You would not be able to flash controllers or anything but you would have dealer scan tool information which is really unmatched by the aftermarket.
