Diagnostic fault codes

Always available online

On-board diagnostics does not replace off-board diagnostics (STAR diagnosis or Wabco controller), as certain functions can only be checked with the aid of off-board diagnostics (e.g. channel assignment of the sensors and actuators of the BS or ABS/ASR sensor system). The systems and fault codes compiled in various XML files here in the download only represent an unreal, maximum equipment scope. However, the scope of the systems that can actually be read out in the On-board diagnostics and diagnostic system depends on the vehicle equipment and technical version. For this reason, some of the systems listed may not be available for the specific vehicle.

The fault codes and associated fault code texts for the current vehicle model series can be downloaded here as a zip file (approx. 65 Mbyte):
