About this document
Reverse Engineering CAN with OBD-II by RonalD gamarra is a document available to read on EtoBox.
1) The document discusses using correlation coefficients to reverse engineer CAN bus messages from OBD-II data when a translation is used. 2) Testing on Audi and Hyundai vehicles found high correlations between some PIDs and CAN IDs, allowing approximate formulas to be determined. 3) However, not all PIDs could be matched this way, and additional testing may be needed to disambiguate ambiguous results. Practical limitations include environmental fluctuations and the number of CAN messages.
