What is the procedure to remove malflags on ECU´s ? Which part has to be read ? Flash via OBD or can i just remove malflags, if the dump is readed via BDM ? I don´t have this case at the moment. Question is just for understanding and learning.. thx

Each type of ecu has different way to erase codes. Some of them have direct codes, other ones has class of error codes that must be disabled. Also, location of error code table is different from table to table.

TIP: Don`t use tools that erase codes because you`ll end up with all trouble codes table erased and i can bet you don`t want that !
