Frequently Asked Questions
What is DAS? – Diagnostic Assistance System – This is the full diagnostic system for Mercedes-Benz vehicles. All functions for diagnosis including reprogramming, configuration, initialization, fault diagnosis and guided diagnostic tests are contained within DAS.
All control unit software (reprogramming calibrations) is contained within the DAS software which is distributed monthly via DVD media.
All access and functionality required in regard the configuration via SCN Coding and/or CVN Coding is covered.
What is WIS-NET? – Workshop Information System – This is the complete workshop information system as developed by DaimlerChrysler for use in the servicing of Mercedes-Benz vehicles. Contained within are installation instructions, procedures, functional and technical specifications. There is some linkage from certain procedures in DAS to respective documents in WIS.
What can Mercedes Star Diagnostic Tool do? The system offers total diagnostic coverage of all engine, chassis and body systems:
Reading and re-setting of diagnostic trouble codes (DTC)
Real-time reading of dynamic data
Full component activation clearing and re-setting of adaptation values
Coding of all engine, chassis, body and instrumentation modules
Key configuration
Procedure for fitting Mercedes- Benz accessories through the D2B ring and MOST bus
Total ASSYST / ASSYST + control (Active Service System) to update on board service history
What is Workshop Green Key? This is a unique one-time key from the factory which is necessary in certain situations such as:
Disabling a key track
Replacing the ECU
Replacing security related control units
Replacing EIS
Typically the workshop key and EIS must be ordered togheter and the green key is used to perform the final programing of the EIS.
What does it mean MARRYING a VIRGIN ECU and EIS? The ME (ECU=Engine Control Unit) and EIS (Electronic Ignition System) control module are electronically permanently married to each other after 40 engine starts. There is no factory procedure to undo this. This means that a used engine EIS or DAS control unit cannot be used on another vehicle. A new control unit can be installed for testing provided the 40 engine starts are not exceeded. Note that the new control unit must be variant coded before it can be used. If the 40 engine start cycles are not completed successfully resetting the counter to 0 (removing the version coding) is possible if you disconnect the power from the ECU for at least 45 minutes.
What model years does Star Diagnostic Scanner work with? The Star Scanner should work on cars from 1989 up to 2015 for Mercedes Cars, Buses, Trucks, Sprinter Vans, Smart cars, Etc.
