MB SD C4 Tourismo bus communication error (fixed)

I bought the MB SD C4+Dell D630 Laptop pre-installed bundle, when I test it have the problem SD Connect C4 cannot power on when connected with  Tourismo bus, I contacted there customer service at obdii365.com, and here is the solution provided by their engineer.

I will explain my problem in detail:

” I have tried 2 different mb sd connect c4 on Tourismo buses and sd connect does not power on.In the meantime those MB SD Connect C4 works normally to any other MB Truck and car.also on Tourismo have check Mb Star C3 and works normally.”

You should check:

bus with OBD
pin 4 + 5
both must be connected and ground

In SDConnect “-” is 5 pin only. There is 4 contact not used in 16pin OBD connector.

“i’m getting an communication error when connecting xentry to a tourismo.”

Tourismo-bus-communication-error-1 Tourismo-bus-communication-error-2 Tourismo-bus-communication-error-3

A Communication error has occurred when access FPS system

Solution:

– turn OFF/ON BUS ground switch (our remove battery – cable). FPS1 wake up and MB Star diagnostic recognized FPS1/VIN code.

or

– enter the DAS ATEGO truck come and place manually and then it will work perfect

” Another problem is : “Currently the speed limit is set to 100 km/h. I’m trying to set it to higher value (with MB SD C4 DAS using modified EOL files). On the menu it tells me that I can, because there are higher values (105 km/h. 112 km/h, etc). But when I try to set the speed limit to higher than 100 km/h it doesn’t allow me to do it (can’t save the changes). When I try to set it below 100 km/h everything goes fine.”

I done the Access special settings , and it working perfect now!

How to test old Benz car before 1996 year with MB SD C4 C5 Star

Many customers contacted:

Why can’t MB SD C4 C5 test the old Benz car?Especially the old Mercedes Benz using the 38PIN diagnostic joint before 1996.

We checked and found that customers used the xentry software in MB STAR C4/MB STAR C5 to test old Mercedes Benz cars.It is wrong.Because the old Mercedes Benz cars before 1996 can only be tested by HTT software which is in DAS.And sometimes we also make a shortcut on the desktop of the computer.

xentry software

For example,In V2019.07 software of the MB STAR C4 / C5, HHT is made as a shortcut on your desktop.

Just click on the HHT icon on your computer desktop to open the software and test your old Mercedes Benz car(before 1996).

If you use V2019.07 software,you can lick and open the DTS icon on your computer desktop图片3.Then choose the old Benz car(before 1996) you want.HHT software will automatically pop up.

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.

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.

Mercedes benz star scanner is a very popular auto scanner in the market. However,Many customer are confused to choose when they want to buy one, because there is four version of mb star:Mercedes Benz Star diagnosis C3, benz star c4, MB star Compact C4 and super Mercedes BENZ C5.

So now,i will summarize their similarity and difference,hope it will helpful for customers to choose.

Similarity:

1.Benz star C3/C4 and MB star sd connect c4,Super MB Star c5 use same software.

2.For the hardware, Benz star C3/C4/C5 is same function in diagnosing.

Difference:

1.For the functions, MB star c3 and c4 are almost the same,C4 can do all the works what C3 does and it is the replacement of Compact C3.
Just benz star c4 size is small and weight is light,much convience and the anti‐interrupting ability is better.
One more thing, as customer feedback, the advantage of c3 is can do trucks best.

2.MB starC3, C4 just can support Mercedes Benz cars manufactured after year 2000. Super MB star c5,Benz SD Connect C4 can support all current and new coming MB vehicles.

3.Benz star c3,c4,SD connect C4 update by Harddisk.That means when customer want to update,they need to send back harddisk to supplier,after finish update,then send back to them again or just buy a new HDD.For the long international distance,it may need about 2 weeks can complete one time update,so it is very trouble and inconvience.

Under this suitation,Super mb benz star c5 is release, it is can update through super mb star official web directly, which will be much convience and time saving.

In addition,Super mb star C5 work with W204, W207, W212, 405, 451, 452 and 454. Besides the software c3 and c4 own,it added three more software: SD Media, Xentry and Smart TAN Code.

SD Media: Video and PDF lessons;
Xentry:New software released by Benz Company after 04/2009 by diagnosis new cars. Xentry software for diagnosing W 204,W207 and W212 which C3 and C4 does not support;
Smart TAN Code: Opened special function in DAS program with Smart cars 405/ 451/452/ 454.Besides, it also opened more special functions, such as engineer mode, remove limitations,etc, which Star C3 and Star C4 do not have.

4.Now we turn to MB star SD connect C4 again.MB Star SD connect C4 not only support KL diagnosis and three lines CAN BUS diagnosis, but also support UDS diagnose protocol, Because it have UDS chips. Star C3,C4,c5 don’t have this chip, so they can not support UDS.

The most advantage of SD connect c4 is: It can connect to PC by wireless or Lan cable.So it will be much more convience than Benz star C3/C4/c5.

Besides, Professional Diagnostic Tools Mercedes Diagnostic Tool star SD connect C4 interface components used the military quickly inserted techniques that can support one million times plug, more stably;And all of the its core components adopt new original packaged chip, plus 24 hours fatigue test, to ensure its stable release.

So in all,each version have its advantage,just see which one is most suitable and interested you.

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.

Benz-diagnostic-and-programming-Benz-Ecom-VS-SD-C4-1

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.
