SD Connect C4 dead, not power up (customer solution)

Share an easy way to repair sd connect c4 multiplexer if your multiplexer is dead, not powering up via any adapter cable.

NOTE:
TRY AT YOUR OEWN RISK!

First open the MB SD C4 main unit. Slide PCB out a little bit, from the connector side, so you can see the units buttons wiring. Carefully pry the lock out & up, after that you can pull the wiring and PCB out.

MB STAR HHT Internal Fault Diagnosis Multiplexer Code 10766

Problem:

I bought the Mercedes Star Diagnostic SD connect C4 diagnostic system. I have installed the XDOS 2015.12V DAS Xentry on Dell D630 laptop, but it gave me two errors:

Error 1:

HHT-WIN display error “Internal fault Diagnosis multiplexer Code:10766”

hht-inetrnal-fault-code-10766

Error 2:

Fault (1.2) Initialization of diagnosis multiplexer failed.

multiplexer-of-diagnosis-failed

Possible reason:

1: HHT error: 2015.12 or newer 2016V Star diagnosis software does not come with HTTWIN software. If you need to troubleshoot old Mercedes, better go for Star software pre-2015.09V.

2.Multiplexer failed: We can see from the error screenshot, MB star Compact C4 icon didn’t show on the status bar which indicates you have not set the SD Connect C4 correctly, so the MB SD C4 is not well communicate with vehicle.

All Benz diagnostic and programming Benz Ecom VS SD C4

New Arrival: Benz Ecom diagnostic and programming tool for newest Benz models. It comes with Dongle and software in the hard disk, activation via remote assistance. Works with newest Benz models instead of old models like MB SD C4.

1.Ecom
Support diagnostic software Xentry, engineering software Vediamo and super DTS Monaco,  it has a than higher access right than SDC4.

Ecom supports the CAN/DoIP protocol, which can be used to diagnose and programming (brushing & writing) for the new car audio and video entertainment systems.

The Mercedes-Benz engineering database of diagnosis / coding / retrofit /flashings is using the Xentry database, so the Mercedes-Benz engineering version depends on the version of Xentry, as long as the database is new, the V4.00 version can be used on new models. compact3 can be used.
SDC4 does not support ODX documents. The latest V5.00 uses eCom to support ODX files. It is recommended to use Ecom, with DoIP function, the speed is faster and more stable.

2.SD C4
Support the diagnostic software Xentry, DAS software diagnostics, engineering Vediamo,  super DTS Monaco, Xentry and DAS Developer mode etc.

Common Name: Developing Data Engineering Edition After 2010
Version, added a lot of functional restrictions. So everyone will encounter the problem that the vehicle version is too new to enter
the control unit, or entering the control unit and cannot make any special modifications. For example: W204 /212 2012
The instrument is needed to modify the regional language configuration or open other convenient functions. With the increasing number of new car with DoIP protocol, the mb star SDC4 has slowly failed to meet market demand.

Normal Star Diagnosis vs Developer Mode

Look here: Where exactly the differences between the normal Star Diagnosis and the Developer Version lie?

Since these differences depend on the DVD version, you will get this nowhere reliable information. The Dev version contains features that are not always released for service and are therefore not available on the “normal” versions of SD. Without another license key there is nothing.
Also, some of the HW and software version of the built-in controller depends. Here are the web many halbgare information to read.

The difference is just the license key.
Other key: More rights and possibilities. For example, there are pure car licenses (Smart, MB …) but also full licenses, with which you can read and work on all Daimler products. In the service, the computers are online, that is, it is not possible to operate a computer easily with a different license

So really a developer tool is not it but that’s why … No one works with us, because we use something completely different. Not so pretty, but much more powerful and flexible than the MB Star C4. But also much error-prone, which one must avoid in the service by all means.

Also, Developermode is available in Xentry. There are a few more things you can do.

But from BR 204/212 etc Sense anyway with big what to do, because everything online. But also gives information on the Internet.

Offline SCN coding mW also with tricks normal but in practice gabs still no success, especially since no need is pending.

This Vediamo should but according to opinions of other specs probably be a good software …

Update:

Quoted:

“This Vediamo should but according to opinions of other specs probably be a good software … let’s see if something can be found.”

This is a pure development tool. The “normal” skilled worker or master in the branch can do almost nothing with it.
Without knowing which “commands” to execute in a particular order, garnix happens.
Did it “coincidentally” but managed to adjust ANYWHERE, ….. yes, and then ??? How do you get that back when things are not going as expected?
So without the expertise of the ECU supervisor, you have no chance.
And even the stupidest …. the necessary description files are there are not

many here in the forum are not even clear with the serial diagnosis, and that is in comparison to children’s stuff.

DTS-Monaco and Vediamo, which better

DTS-monaco and Vediamo are added to MB Star C4 software since 12-2017.
20-1

but what is DTS-monaco and what is Vediamo? And what\s the difference?

Look here:

20-2

What is DTS-monaco:

DTS Monaco is universal Engineering Tester for Diagnostic and Control Functions of Vehicle

ECUs. The name Monaco is derived from Modular Analyzer for Vehicle Communication.

DTS Monaco comprehensively covers all tasks in the areas of engineering, testing and

preparation of manufacturing tests:

*   diagnostics
*   analysis
*   OBD
*   flash programming
*   measuring
*   parameterizing
*   residual bus simulation
*   OTX

MB SD C4 DTS Monaco is based on standards such as ODX, OTX and UDS

20-3

What is Vediamo:

Vediamo Software is used by the plant engineers to develop diagnosis and engineering software, which is now used by Xentry and DAS, is based on the Mercedes Benz super engineering version developed and delivered to the general customer service dealers’ use.

The use of MB super engineering version has no limitation in diagnosis / modification / programming function are open which cannot be through the VEDOC (the original application code changes with flow) can be free to increase or decrease the SA code, modify the objective, for example: the increase of vehicles equipped with SA500 electric folding mirrors, commonly known as the Xentry and DAS development mode: open data project version in 2010 after the release, increase the number of functional limitations. So we will meet the vehicle version is too new to be into the control unit in use, or are unable to do any special modifications to the control unit.

For example: W204/2122012 instrument to modify the area family configuration, or open other resource advantage function. Diagnosis / Mercedes super engineering version of the code with code / modification / programming database using the Xentry database, so the Mercedes Benz super engineering version is determined with the Xentry version, as long as the database is new and can be used in new models.

Vediamo M Mode Variant Coding W212 7G

Some important tips of Mercedes Benz W212 7G M Mode Variant Coding using Vediamo.

Purpose:

W212 7G M Mode Variant Coding

You need:

Vediamo running with Sd connect C4

SCN coding database

Variant code:

Y2KY

BetaMar

I want to have M-mode in W212 E500 4matic 2010 model 212.090 SA801 – YOM 10/1, at the moment my variant code is Y2KX, does anyone help me to know the right code for M-mode ?

StarRacer

That’s interesting. I’ve got nearly the same car (W212 from 2009) and I’m also looking for the manual mode. My variant code is Y2KY.

Someone recommended to try three codings before and after the current one but I’m a bit hesitant with this.
The coding contains several properties of the car including 4Matic or RWD. In contrast to the RWD ones, the MB Star have a torque limitation to protect the gearbox etc. when starting with full throttle. Therefore, a genuine 4Matic variant code would be preferable.

I think in the 7G coding collection there was no W212 E500 with M-mode. The next “match” could be an S500 4Matic (221.086). From the thread mentioned its variant code is YE25. Not sure if this one has M-mode, though.

BetaMar

I want to confirm that in 212.090 with MY2010 SA801 M-mode work very well

with Y2KZ ?? Imidietly after coding there was error showed in KI display “presafe function is unavaiable” but after ignition off/on everything works!

For 212.090 MY2009 SA800 correct coding is Y2AR

StarRacer

SUCCESS! Now with working M-mode! Y2KZ also works for me. Same error as above after first start which went away with the 2nd start.

Test drive was successful. One drawback, however: The gear switching times in M are not better than in C or S. Some years ago, I read from an S211 (E500 M273 with 7g) which was given M-mode and the owner claimed significantly faster gear switching. He did it the official way: Changing VeDoc and MB Star C4 online SCN coding. Maybe there’s more to it than just the VGS variant coding.

Good luck
