Yeah that's what I finally did.. Filtering in code.. And today it worked on a hybrid Civic with 4 computers!! Probably ECU, TCU, electronic motor control unit and battery controller unit..! It has ISO 15765-4 (CAN 29/500) with 4 header bytes.... I thought it would have the standar 7Ex header but it was different, however with proper code I managed to get it to work..
Do you have any link where I can see the standards for each protocol? I would like to see the headers actually..
