DTS Monaco - Mercedes Benz OBD2 Diagnostic & Programming 9.02

Let me answer both questions:

The XPRJ Files:
Those are Xentry project files, not the SMR-D files Monaco needs. They are in the wrong folder. The SMR-D files are somewhere else on that SSD. Do a full drive search:

1. Click on the SSD drive letter.
2. In the search bar type: *.smr-d
3. Let it search the entire SSD. Be patient, it could take 10-15 minutes.
4. If it finds hundreds of .smr-d files, that is your database.
5. If it finds ZERO, then your Xentry SSD does not have the extracted database and you need to boot from the SSD and run Xentry first to unpack them.

Now The Big Problem - Your Batteries:

This is a serious issue. Your HV battery is at 0% and your 12V is dead. Here is the reality:

You CANNOT code with a dead 12V battery. The car needs the 12V to power all the ECUs and the OBD port. No 12V = no communication = Monaco cannot talk to anything.

But here is the dangerous part:

Your HV battery is at 0% because the crash flag is preventing the charger from working. And you cannot clear the crash flag without the 12V being alive. So you are stuck in a loop.

Here Is Your Way Out:

1. Get a 12V battery charger or jump box.
2. Connect it to your 12V battery under the hood.
3. Do NOT try to start the car. Just turn ignition to ON position.
4. This will power up all the ECUs.
5. Connect your VCX to the OBD port.
6. Now do the crash reset in Monaco.
7. Keep the 12V charger connected the entire time you are working. Do not disconnect it.

Important: A regular jump box might not hold long enough. I would recommend a proper 12V battery charger plugged into a wall outlet set to maintenance mode. You need stable 12V power for at least 30-60 minutes while you work through the crash reset process.

Once the crash flag is cleared and you plug in the AC charger, the OBC will start charging the HV battery and the HV battery will start charging the 12V automatically. Everything comes back to life once that crash flag is gone.

Yea I believe I have everything installed on my c drive for xentry then on my ssd I have Monaco and the other apps

Ok so it is the opposite of what we were thinking. Let me straighten this out:

Your Setup:

• C: Drive = Xentry installed
• SSD = DTS Monaco and other tools

So the SMR-D files should be on your C: drive where Xentry is.

Do This Right Now:

Step 1: Search Your C: Drive
1. Open File Explorer.
2. Click on Local Disk (C.
3. In the search bar type: *.smr-d
4. Let it search. Be patient, could take 10-15 minutes.
5. If it finds hundreds of files, you are good. Note the folder path.

Step 2: If Nothing Found
That means Xentry was never fully run and the database was never unpacked. You need to:

1. Open Xentry on your C: drive.
2. Let it fully load and initialize for the first time.
3. This can take 20-30 minutes. Let it do its thing.
4. Once it fully opens to the main screen, close it.
5. Now search for *.smr-d again on C: drive.

Step 3: Once You Find Them
Since Monaco is on your SSD, you have two choices:

Option A: Copy the SMR-D files you need (OBC223, SGBMS, ACSM, HVSG) from C: drive over to your SSD where Monaco is and load them there.

Option B: Point Monaco's project database import to the C: drive path where the files are. Monaco does not care where the files are located as long as you can browse to them.

But First Priority:
Get that 12V battery charged. Without it nothing else matters. While the 12V is charging on a wall charger, use that time to find the SMR-D files and get Monaco set up properly. That way when the 12V is ready you can immediately connect and start the crash reset.

If I have xentry file in ssd can I just click

No, it is not that simple. It depends on how Xentry was installed on your SSD.

If you just copied the Xentry files or folders onto the SSD, you cannot just double click and run it. Xentry needs to be properly installed with all its services, drivers, and registry entries. Just copying files does not work.

But wait, let me ask you this:

Where exactly is Xentry that you actually use? Think about it:

• When you open Xentry, do you click a shortcut on your Desktop?
• Or do you boot from the SSD?
• Or do you have never actually opened Xentry at all?

This is important because if you have never actually run Xentry, then the SMR-D database has never been unpacked anywhere. That is why you cannot find the files.

Tell me this:

1. Have you ever successfully opened Xentry and seen the main screen?
2. When you did, were you booted into your normal Windows or booted from the SSD?
3. On your C: drive, do you see a folder at C:\Program Files\Mercedes-Benz or C:\ProgramData\Mercedes-Benz?

Once I know this I can tell you exactly where your SMR-D files are or if they even exist yet. Because right now it sounds like Xentry might have been installed but never actually run, which means the database is still packed up and Monaco has nothing to read.

Do I need the whole openshell zip on my c drive or installing xentry is goood enough

Just installing Xentry is NOT enough for what you need.

Here is the difference:

Xentry alone:

• Just the diagnostic program
• Does NOT include the full SMR-D database that Monaco needs
• Can read codes and do basic stuff

OpenShell (the full package):

• Contains Xentry
• Contains the full ODX database with ALL the SMR-D files
• Contains all the ECU definitions Monaco needs
• Contains the security access data
• This is where OBC223, SGBMS, ACSM, HVSG all live

So yes, you need the full OpenShell package extracted on your C: drive. That is where the SMR-D database comes from.

Here Is What To Do:

1. Get the full OpenShell zip.
2. Extract it to your C: drive. It is a big file so make sure you have enough space. Usually needs 50-100GB free.
3. Let it fully extract. Do not interrupt it.
4. Once extracted, look for the ODXProjekte folder inside it.
5. Inside there you will find all the SMR-D files.
6. Now point Monaco to that folder.

This is why you could not find any SMR-D files anywhere. You never had the full database installed. You had Xentry without its brain basically.

While your 12V battery is charging, download and extract the full OpenShell package. That will solve your missing file problem and Monaco will finally have everything it needs to do the crash reset.
