Unfortunately, FORScan is primitive technology against my application I use primarily. It doesn't display, nor translate nearly the amount of information as my primary choice of software. What I have discovered lately is that the APIM
holds much more data related to other parts of the vehicle rather than just simply how many station presets it can show and if you have heated or cooled seats.
As per a previous post of mine, I cannot confirm the reasons as to what the APIM
has to do with any of that information. My assumption is it acts as a bridge of communication to relay information to the rest of the vehicle, or it holds said data to correspond vehicle updates and security features. I believe it is the latter. FORScan unfortunately does not have the ability to interpret what modules act as gateways for one another or what networks relay specific blocks between each other. It simply provides manipulable data in the form of Hexadecimal for all responsive modules within a vehicle. I'm extremely curious as to where FORScan would translate how, where, and why the APIM
is a gateway because to my knowledge it can't do that. I can also say the exact same goes for my own application. It simply translates bit values, but substantially more in depth than FORScan. This data also being found in the BCM
is absolutely correct. However, if the APIM
is a "gateway", I by all means should not have any capacity to alter fuel type, transmission properties, parking brakes, and other entities through the APIM
. However, I do pertain aptness of such and that is why I've concluded the APIM
physically holds data related to the mechanics of the vehicle.
For quick reiteration, FORScan and my own application do not have the ability to represent a module as a gateway into another module. There's no cogent reason for that. They lucidly present translated data within a singular module.
We are always open to education and growing our base of knowledge as I'm sure we can all agree upon. I'm typically very responsive and more than willing to provide as much knowledge as asked. If you have any other questions regarding this topic, you're more than welcome to send me a PM.
