XENTRY WIS + Dynamic Wiring Diagram for Passenger Cars Online Access

XENTRY WIS (Workshop Information System) + Dynamic Wiring Diagram (DWD) for Passenger Cars Online Access is the official, web-based Mercedes-Benz service and repair platform. Designed for independent workshops and automotive technicians, this cloud-based solution provides instant access to the most comprehensive maintenance, repair, and technical data for Mercedes-Benz and Smart passenger vehicles. It integrates the traditional WIS documentation—such as repair instructions, maintenance schedules, and troubleshooting guides—with the next-generation Dynamic Wiring Diagram (DWD) system. DWD replaces static electrical schematics with an intelligent, interactive interface that allows users to dynamically trace wiring, locate components, and analyze electrical signals in real-time, all directly through a standard web browser without the need for local software installation.

Function

• Workshop Information System (WIS): Provides step-by-step repair instructions, maintenance service sheets, tightening torques, and technical service data.
• Dynamic Wiring Diagrams (DWD): Offers interactive and intelligent electrical schematics. Users can zoom, pan, highlight individual wires, and trace power or ground paths dynamically. Components are hyperlinked directly to their respective repair documents.
• VIN-Specific Documentation: Automatic vehicle identification via VIN decoding ensures that technicians view the exact, model-specific wiring and repair data corresponding to the vehicle’s production year and installed options.
• Diagnostic Troubleshooting: Provides guided diagnostic test procedures, fault code analysis, and component testing parameters (e.g., expected resistance, voltage values).
• Component Locator: Visually identifies the exact physical mounting location of electrical components, relays, fuses, and ground points on the vehicle.
• Flat Rate Units (FRD): Displays standard labor time allowances for specific repair and maintenance operations to assist with customer quoting and invoicing.
