	The on-board diagnostics doe not replace the off-board diagnostics (STAR diagnosis or Wabco controller), as some functions can only be checked using the off-board diagnostics (e.g. the channel allocation of the sensors and actuators of the EBS or ABS/ASR systems).
	The systems grouped here in a single table depict only an imaginary, maximum equipment configuration. The configuration of the systems which are actually read out in the OBD, however, depends on the vehicle equipment and the technical design. Therefore, it may not always be possible to call up some of the listed systems on the actual vehicle.
