Response sent to Mr. Saveliev: There is a matrix for light duty, but it isn't as complete as one would like. It doesn't drill down to specific systems. It can be assumed that the protocols in these sheets pertain to drive-train only. Here are some links. This one covers older vehicles Every 2008 and newer light-duty vehicle must use the CAN protocol J2284 (US) or ISO 15031 (International), theses specs are almost identical. Heavy duty is not listed in the above spreadsheets, but it can be assumed that all U.S. manufacturers use J1587/J1708 or J1939 CAN on most OBD equipped engines. European and Japanese engines are more likely to use either ISO 14229 UDS and ISO 15031.
