I am new in SCoA, and this my very first post here.
I own a 2015 ForTwo 451 and, as electronics engineer, I have not resisted (since some months ago) to the temptation of listening the traffic on the CAN bus (the one broadcasted by the different modules) and also performing some request through PID OBD2 codes. I have had some degree of success with parameters like status of lights, gear selected, doors' status, etc.
But on the other hand, other parameters looks to be hidden very deep, (or I have missed something...
In this regard I have couple of questions that, hopefully, some of you could answer or just clarify the point a little for me:
1 - Is there any known ID message (proprietary message, of those broadcasted by the modules) that carries the fuel level information, same shown in the instruments cluster by the eight steps fuel bar at the bottom? Or, is there any way I could get that information (perhaps a query code needs to be put on the bus)?
My understanding is that this information reaches the A1 instrument cluster through the CAN bus, so it should be carried by one the messages present on it...
2- A similar question, but in this case for the odometer. I mean, not the total number of kilometers accumulated by the car during its life, but just the trip distance. I have identified the total km on the CAN bus already, but its resolution is 1 Km. The trip accumulated distance increments are 0.1 Km, more accurate...
If some of you have this information and is willing to share it (BTW, this is for personal use, not commercial at all), or just point me in the right direction, it is appreciated in advance very much..!
