What is SCN Online Coding Mean?

SCN stands for Software Calibration Number, which means software calibration, centralized and near-automatic coding to prevent wrong selection when replacing modules.

SCN online coding is performed when the technician wants to replace the module or add new updated software to replace the old problematic software by connecting to the engine ECU. When you want to add modules or update new software for your vehicle, some errors may arise. SCN coding is the best solution to solve problems with new updates.

SCN online coding is a special feature and should only be released to Dealers. You need to have an SCN coding online account to use it to code the Engine control unit(ECU). A more convenient alternative to utilizing the SCN feature is through an offline approach, which involves acquiring the software discussed in the subsequent content. This offline method offers a streamlined and accessible way to leverage SCN functionalities.

Why is SCN coding important?

SCN coding can be generated by authorized dealer staff through any computer with the internet or any NetStar Terminal. For example, if you are having problems with the transmission, it may be a problem with the ME Control Unit and you need SCN coding to fix the problem.
SCN coding will always be required after replacing most Mercedes-Benz systems, for example:

ABS
SRS airbag computer
Gearbox module
Keys Programming
ME module…

You will need SCN online coding for the additional installation of future control modules. It will also ensure that your vehicle will function optimally. And the SCN code is also required to prevent any aftermarket enhancements from being made to improve performance.

Advantages – Disadvantages of SCN Online Coding

Advantages: Mercedes internal online coding program, connecting repair and coding directly on the vehicle. Read and clear errors, reset control boxes quickly and change parameters of previous setting values,…
Cons: Currently blocked online SCN encryption system worldwide, only can be used by an authorized Mercedes dealer.

So when SCN online coding has been blocked worldwide but needs to re-code the software, what to do?
Currently, after SCN coding online is blocked, DTS Monaco and Vediamo software are two life saving offline encryption software for technicians. Both software support coding, error reading and Mercedes programming. DTS Monaco supports new models and Vediamo supports old models. If you want to learn more about the software, please refer to the article!

How to get SCN Coding Account?

As mentioned above, the SCN coding online account is only issued exclusively for genuine dealers. Therefore, Mercedes released 2 offline coding software to perform coding and programming functions to support the car repair process. These two software are Vediamo and DTS Monaco.

VEDIAMO Software

Distributed diagnostics with multiple, simultaneous special client applications, e.g., test run control over PSR adapter while simultaneously verifying with Ecoute
Expansion of the system by additional clients
Diagnostics, coding, or flashing of multiple ECUs simultaneously

DTS Monaco

DTS Monaco Engineer software is a great partner in a time when SCN online is blocked.

Special features:

Quick Check: Quick check of the entire vehicle ECU and selectable test for further editing
Diverse encoding
ID recognition: One click to read the entire vehicle and save all the model’s programmed numbers – boil 4.
Complete variant encoding: One read of all vehicle ECU encoding data, can be written to the vehicle again, working completely offline.
Diagnostic service: Advanced features can see the difference between you choose internal and external data modules, activate computer authorization (not driver’s license), Activate ECU, set ECU again, modify
the original chassis number
Flash Programming: Completely Offline Programming
Diagnostic trouble code: Diagnostic module Error code DTC
ECU Exchange: Two of the ECUs are the same, by reading the exchange data input.
Symbol Trace

Currently, SCN online coding has been blocked, so currently 2 software Vediamo and DTS monaco are two specialized software that support offline coding and programming for current Mercedes models.
