3. General information
If one of the three readiness codes (RC) on BMW diesel vehicles with OBD be registered
by the Generic ScanTool as "not positively concluded", this is not a reason for a "failure" in

The status of the RCs is merely recorded in the test certificate - it is not evaluated!
The system tests for the three subsystems are always performed by the DDE control unit,
but their results are not always communicated correctly to the ScanTool due to a differing
interpretation of the communication protocol.
