This is the first time I have been stuck trying to figure out a code and I don't want to buy parts for the sake of buying parts

Well if youre familiar with BMWs then I would be using INPA instead of ISTA as ISTA is rather clunky. It's nice, but clunky.
To andrew's point, you need to be actually reading what the DSC is interpreting the data is. INPA does not have graphing capability in terms of plotting, but it does have bar graphs for typical ranges. The reason why andrew suggests this as you can have sensors fail within range and do funky things because the DSC has those printed bond wires that can and do go bad.
I've used ISTA a couple times and have got it to do some service routines as it is
possible.
Here is just an example of a DSC and the values it's reporting using INPA. Clear, concise, and no fluff.
Good luck. And let us know what you find.
