The MB Workshop Information System (WIS+ASRA+DAS) DaimlerChrysler AG's aim is to improve the electronic availability and usefulness
of the workshop documentation (e.g. repair, maintenance, basic data, wiring diagrams and in part also documentation organization) of Mercedes-Benz and smart products by optimizing access and presentation.

  accompanying this.

• Automated documentation search.
  
• Damage coding (for warranty settlement).
  
• Call of the vehicle datacard from the EPC system with code identification written in full.
