The bDiag module is not just an OBD2 scanner but a complete error code reader that has a native module for almost all car brands. The problem with the OBD2 error codes is that some errors aren’t assigned to an OBD2 error code so they don’t show on the diagnostics, also often many different errors set the same OBD2 code, so it’s not very accurate. bFlash will first give you the manufacturer specific code with description and where available also the OBD2 code.
Thanks to to DTC Finder function in the bManager, you can easily deactivate any of the found error codes in the ECU file. Making the combination of the bDiag and bManager a valuable tool for tuners. You can just drag/drop your error report into the bManager and the errors will be deleted from your tuningfile.
