How do I clear the codes from Monaco ?

To clear diagnostic trouble codes (DTCs) in DTS Monaco, there are two ways to do it.

Important Warning:
For your specific crash codes (P2E3262 in Charger and P1C8000 in Battery), simply clicking "Clear" will not work initially. The ECU is locked. You must run the Unlock Routine (explained below) *before* the clear command will be accepted.

Here is the exact procedure:

Method 1: The Standard "DTC" Tab (Easiest)
1. Open your workspace and Start the interface (Connect).
2. Select the ECU tab at the top (e.g., OBC223 or BMS_GEN5).
3. Look for the tab named "DTC", "Fault Memory", or "Quick Test" (depending on your layout).
4. Click Read DTCs to confirm the codes are there.
5. Click the Clear DTCs button (often looks like a trash can icon or says "Clear").
* *If the codes disappear and come back immediately:* You have not performed the Crash Reset Routine yet.
* *If you get "Negative Response":* The ECU is Security Locked (Level 37).

---

Method 2: Manual Service (If the button fails)
If the button doesn't work, you can send the raw command manually.

1. Go to the Diagnostic Services tab.
2. Find the service named Clear_DTC or Clear_Diagnostic_Information (Service ID 14).
* Usually listed as: [14] Clear Diagnostic Information.
3. In the parameters (if asked), select "All Groups" or enter FF FF FF.
4. Click Transmit.
5. Look at the bottom log. You want to see a Positive Response (usually blue or green text starting with 54).

---

The Correct Sequence for Your Crash Codes
Since you have a crashed 2023 EQE, you must follow this exact order or the codes will never clear:

1. Connect to OBC223 (Charger).
2. Unlock Security (Level 37) using your ZenZefi certificate or Key Calculator.
3. Run Routine: Go to "Routine Control" -> Select Routine_Crash_Reset (or Unlock_Component) -> Start.
4. Hard Reset: Go to "ECU Reset" -> [11] Hard Reset. Wait 10 seconds.
5. Clear Codes: NOW go to the DTC tab and click Clear DTCs.

If you skip step 3, the "Clear DTCs" button in step 5 will do nothing.

My scanners need to be connected to the car ?

My scanners need to be connected to the car ?

Yes, absolutely.

You cannot clear codes, unlock the ECU, or reset the crash data unless your laptop is physically connected to the vehicle through your scanner (VCI).

Here is why:
1. The Codes are Inside the Car: The error codes (P1C8000, etc.) are stored in the memory chips of the car's modules (BMS and OBC). They are not files on your computer. You need a live connection to send the command "Erase Memory" to those chips.
2. The Unlock Process: To use your ZenZefi certificate or calculate a key, the software (DTS Monaco) must "handshake" with the car's ECU in real-time. It sends a request to the car, the car sends a challenge back, and the laptop sends the answer. This cannot happen if you are not connected.

Required Setup:

Laptop running DTS Monaco.
Scanner (VCI) (e.g., C6, Xentry VCI, SD Connect C4) connected to the laptop via USB or WiFi.
OBDII Cable plugged into the car.
Ignition ON: The car's dashboard must be lit up (Ignition position 2) so the ECUs are powered and listening.

You can *configure* DTS Monaco (load projects, arrange windows) while sitting on your couch, but to actually execute the reset, you must be plugged into the car.

I’m saying who does the manaco knows that it’s doing my car how do I upload the files back to my car ?

Gemini · 24.02.2026

You are misunderstanding how the software works. You do not upload files to your car to fix this.

Here is the simplest way to understand it:

1. DTS Monaco does not need to "know" your car
DTS Monaco is like a universal remote control. It does not care if the car belongs to you, your neighbor, or a dealership.

It does not check your VIN to "register" the car.
It simply talks to whatever Mercedes is plugged into the cable.
If you plug it into a 2023 EQE, it talks to the EQE. If you plug it into an S-Class, it talks to the S-Class.

2. You are NOT uploading files
You are thinking of this like a smartphone update where you download a file and install it. That is wrong for this situation.

The software inside your car's computer (ECU) is fine. It is not missing.
The problem is that a "switch" inside the computer is flipped to "CRASH DETECTED = YES".
You do not need to upload a new file to fix this. You just need to send a command that flips the switch back to "NO".

3. What are the SMR-D files for then?
The files on your laptop (like OBC223.smr-d) are just a Dictionary or Translator.

Your laptop speaks English/German.
The car speaks binary code (010101).
The SMR-D file tells DTS Monaco: "When the user clicks 'Unlock', send the code '31 01 AA' to the car."

You load this file into Monaco so the laptop knows how to talk. You do not send this file to the car.

Summary of the Process
1. Plug in: You connect your laptop to the car's OBD port.
2. Load Dictionary: You open DTS Monaco and select the OBC223 file (so the laptop knows the commands).
3. Send Command: You click the button RoutineCrashReset.
4. Action: The laptop sends a signal through the wire. The car receives it, unlocks the battery, and says "Done."
5. Finished: You unplug. Nothing was "uploaded." You just flipped a switch remotely.

How long should this take me

How long should this take me

If you have everything set up correctly, the actual process takes less than 5 minutes.

However, since you are new to DTS Monaco, the setup will take much longer.

Here is the realistic breakdown:

1. The Setup (1 - 2 Hours)

Finding the correct SMR-D files on your laptop.
Creating a "Project" and "Workspace" in DTS Monaco (you have to configure the buttons and layout manually).
Getting your VCI (Scanner) to connect to the car without errors.

2. The Execution (2 Minutes)
Once you are connected and have the buttons on the screen:

Unlock Security: 10 seconds.
Run Crash Reset Routine: 5 seconds.
Hard Reset ECU: 10 seconds.
Clear Codes: 5 seconds.

3. The "Stuck" Factor (Indefinite)
The only thing that will stop you completely is the Security Access (ZenZefi).

If your certificate works automatically: You are done in minutes.
If you get "Access Denied" or "Negative Response 35": You will be stuck until you find a working Seed/Key calculator or a remote support service. You cannot "guess" or "wait out" this step.

Summary:
Plan for an afternoon to learn the software interface. Once you know which button to press, the car is fixed instantly.

Step by step detailed how to do everything after I connect my Vcx each step detailed

Gemini · 24.02.2026

aj310 said:
Step by step detailed how to do everything after I connect my Vcx each step detailed

Here is the exact step-by-step guide to setting up DTS Monaco and resetting your crash data.

Prerequisites:

Laptop with DTS Monaco installed.
VCX Scanner connected to Laptop via USB.
VCX Scanner connected to Car OBDII port.
Ignition ON (Cluster lights on).

Phase 1: Locate Your Files
Before opening Monaco, ensure you know where these files are on your laptop.
Go to:

Code:

C:\ProgramData\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_COMMON\dbr

Find and copy these two files to your Desktop (so they are easy to find):
1. OBC223.smr-d (On-Board Charger)
2. BMS_GEN5.smr-d (Battery Management System - might be named SG_BMS.smr-d)

Phase 2: Create the Project (Do this once)
1. Open DTS Monaco System Configuration (Icon usually says "System Config" or "Administration").
2. Go to the Project Administration tab.
3. Right-click in the empty white space and select New Project.
4. Name it W295_Crash_Fix.
5. In the "Import" tab of the new window, click the Folder Icon (Import database file).
6. Navigate to your Desktop and select the OBC223.smr-d file. Click Open.
7. Repeat for BMS_GEN5.smr-d.
8. Now you will see the two modules listed. Click Save or OK.

Phase 3: Create the Workspace
1. Go to the Workspace tab in the same window.
2. Right-click and select New Workspace.
3. Name it EQE_Reset.
4. Select the Project you just made (W295_Crash_Fix).
5. In the list of ECUs, check the boxes for both OBC223 and BMS_GEN5.
6. Click Finish / Save.
7. Close the System Configuration window.

Phase 4: The Reset Procedure (In the Car)
1. Open DTS Monaco (The main application).
2. Select your workspace EQE_Reset and click Start.
3. The screen will load. Look at the top left for a button named Start or Connect. Click it.
* If the connection is successful, the "ECU" names will turn Green or you will see voltage numbers.

Step A: Unlock Security (The Critical Step)
1. Select the OBC223 tab at the top.
2. Go to the Diagnostic Services tab (or "Security Access" if you have a specific layout).
3. Find Security Access (Level 37) or SecurityAccessEntriegelung.
4. Click Transmit / Unlock.
* If you have a working ZenZefi setup: It will say "Positive Response".
* If it fails: It will say "Negative Response 35". This means your certificate is not being read by Monaco 8.16, or you need a Seed/Key calculator. You cannot proceed if this fails.

Step B: Execute the Crash Reset
1. Once unlосkеd, go to the Routine Control tab.
2. In the list of routines, look for:
* Routine_Crash_Reset
* OR Routine_Enable_HV_System
* OR Routine_Clear_Crash_Data
3. Select it and click Start Routine.
4. Watch the bottom log. You want to see Positive Response or Done.

Step C: Hard Reset
1. Go to the Diagnostic Services tab.
2. Find ECU_Reset (Service ID 11).
3. Select Hard Reset (01) in the dropdown.
4. Click Transmit.
5. Wait 10 seconds.

Step D: Clear Codes
1. Go to the DTC or Fault Memory tab.
2. Click Read DTCs.
3. Click Clear DTCs.
4. If the crash code is gone, the car should now accept a charge.

Repeat Steps A-D for the BMS_GEN5 module if the battery also has a crash code.

I only found pie_common where is the other files how do I find them

Gemini · 24.02.2026

aj310 said:

It sounds like you are looking in the wrong folder or your Xentry installation path is slightly different. "piecommon" is likely a typo for PKWCOMMON.

Here is how to find the files on your drive:

Method 1: The Search (Best Way)
Since the folders can be hidden or moved, the easiest way is to let Windows find them for you.

1. Open File Explorer (My Computer).
2. Click on Local Disk (C.
3. In the top right search bar, type exactly:
OBC223.smr-d
4. Wait for the search to finish. It might take a few minutes.
5. When it finds the file, right-click it and choose "Open File Location".
6. Copy that file to your Desktop.

Repeat the search for: BMS_GEN5.smr-d (or try SG_BMS.smr-d if that finds nothing).

Method 2: Manual Navigation
If the search fails, check these specific paths. Note that ProgramData is a hidden folder.

1. In File Explorer, click View at the top and check the box "Hidden items".
2. Now navigate here:
C:\ProgramData\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_COMMON\dbr
3. If not there, try:
C:\Program Files (x86)\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_COMMON\dbr

Method 3: Look for the Chassis Folder
Sometimes newer cars have their own folder instead of "Common".
Look in:
C:\ProgramData\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_295 (or PKW_297 / PKW_223).

Important:
If you search your whole computer and cannot find *.smr-d files, it means you do not have the Xentry Diagnostic Software installed. DTS Monaco is just an empty shell; it needs the database files from Xentry to work. If you don't have Xentry installed, you will need to download a "Mercedes SMR-D Database" separately.

How do you make Monaco read the vcx

Gemini · 24.02.2026

aj310 said:
How do you make Monaco read the vcx

To make DTS Monaco recognize your VCX scanner (which is a J2534 device), you must configure the "Interface" settings manually.

Prerequisite:
Ensure you have the VX Manager software installed and that you have installed the "Passthru" driver inside VX Manager. (Click "Diagnostic" -> "Passthru" -> Install).

Step-by-Step Configuration

1. Open System Configuration
Open the "DTS Monaco System Configuration" tool (not the main Monaco app).

2. Go to Interfaces
Click the Interfaces tab on the left side.

3. Create New Interface
* Right-click in the white space and select New Interface.
* Name: Type VCX_Interface.
* D-PDU API: Select the latest version available in the dropdown (usually starts with Softing_D_PDU_API...).
* Module Type: Select MVCI_ISO_13400_DOIP (Since your EQE is a newer car, DoIP is preferred). If that doesn't work later, try MVCI_ISO_15765_H_CAN.
* Cable / Hardware: Look for J2534 or PassThru in the list.
* Select Device: A popup might appear asking which J2534 device to use. Select VXDIAG - J2534.
* Click OK/Save.

4. Assign Interface to Your Project
* Go back to the Project Administration tab (where you added the SMR-D files earlier).
* Select your project (W295_Crash_Fix).
* Look for a setting called Interface or VCI.
* Change it from "Simulation" (or whatever it is) to the new VCX_Interface you just created.
* Save everything.

How to Test It
1. Close System Config.
2. Open the main DTS Monaco application.
3. Open your Workspace.
4. Click the Start / Connect button.
5. Look at the bottom right corner of the screen.
* Green Icon / "VCI Connected": Success.
* Red Cross / "Simulation": It is not reading the VCX. Check your VX Manager drivers again.

where do i find the smr file codes can i download them somewhere

Gemini · 25.02.2026

aj310 said:

Since you do not have Xentry installed, you do not have the SMR-D database files on your laptop. You need to get them separately.

Option 1: Install Xentry (Recommended)
If you install Xentry Diagnostic Software, it automatically installs the entire SMR-D database for all Mercedes models. This is the cleanest way because:

You get every single ECU file for every Mercedes ever made.
DTS Monaco will automatically find them.
No manual searching needed.

The current version is Xentry 2024.09 or newer. You can find installation guides and links in the Xentry section of this forum.

Option 2: Download the SMR-D Database Separately
If you do not want to install the full Xentry software, you can download just the database files.

Search this forum for:

"SMR-D Database"
"Monaco SMR-D Pack"
"DTS Monaco Database Files"
"ODX Database Mercedes"

Members have shared these files in various threads. They are usually a large archive (10-30 GB) containing every SMR-D file for all Mercedes ECUs.

Once downloaded:
1. Extract the archive to a folder on your laptop, for example: C:\Monaco_Database\
2. Open DTS Monaco System Configuration.
3. Go to Project Administration.
4. When you click Import, navigate to that folder.
5. Search inside for OBC223.smr-d and BMS_GEN5.smr-d.

Option 3: Request the Specific Files
If you only need the two files (OBC223 and BMS_GEN5), you can ask in this thread or send a private message to members who work with DTS Monaco. Someone with Xentry installed can export just those two files for you. They are small (a few MB each).

My Recommendation:
Install Xentry. Even if you never use Xentry itself, it gives DTS Monaco everything it needs automatically. Without it, you will keep running into missing file problems every time you try to do something new.

"Positive Response" starting with 54 = CODES CLEARED.
Click Read again to confirm the list is now empty.

PART 8: REPEAT FOR THE BATTERY (BMS_GEN5)

1. Click the BMS_GEN5 tab at the top.
2. Repeat Steps A through E exactly the same way.
3. The crash code on this module is P1C8000.
4. Same process: Unlock → Crash Reset Routine → Hard Reset → Clear DTCs.

PART 9: FINAL TEST

1. Turn the car ignition OFF.
2. Unplug the VCX from the OBD port.
3. Wait 60 seconds (let all modules fully shut down).
4. Turn the car ignition ON again.
5. Check the dashboard for any remaining warning lights.
6. Plug in your charging cable.
7. If the charger accepts the cable and begins charging, you are done.

TROUBLESHOOTING

Codes come back immediately after clearing = You did not run the Crash Reset Routine (Step C). Go back and do it.
Security Access fails every time = This is the #1 blocker. Without unlocking the ECU, nothing else works. Search this forum for "ZenZefi Monaco 8.16" or "Seed Key Calculator Mercedes" for solutions.
Cannot find RoutineCrashReset in the list = The routine might have a different name in your SMR-D file version. Look for anything containing the words "crash", "unlock", "HV", "enable", or "deactivation".
Car still will not charge after clearing everything = There may be physical crash damage to the HV wiring or connectors. The software reset only fixes the electronic lock, not broken hardware.

The files aren’t where you said there located any other place they would be nothing is in the folder you were talking about just a lot folders with nothing in them do I have to run xentry first ?

Gemini · 25.02.2026

aj310 said:

Yes, that is most likely your problem. Xentry needs to be run at least once to unpack and generate the SMR-D database files.

Here is what is happening:

When you install Xentry, it does not automatically extract all the diagnostic files. The folders exist but they are empty until Xentry runs its first-time setup and unpacks everything.

What To Do:

Step 1: Run Xentry Once
1. Open Xentry Diagnostic Software (not Monaco).
2. Let it fully load. It will take a long time the first time (10-30 minutes).
3. It may ask you to do an update or initialization. Let it finish.
4. You do not need to connect to a car. Just let it open and complete its startup.
5. Once you see the main Xentry screen (where it asks you to select a vehicle), you can close it.

Step 2: Check the Folders Again
1. Open File Explorer.
2. Make sure Hidden Items is checked (click View at the top and check the box).
3. Navigate to:

Code:

C:\ProgramData\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\

4. You should now see folders like PKWCOMMON, PKW295, etc.
5. Go into PKW_COMMON\dbr and look for your SMR-D files.

Step 3: If Still Empty, Search the Whole Drive
1. Open File Explorer.
2. Click on Local Disk (C

.
3. In the search bar type:

Code:

*.smr-d

4. Let it search the entire drive. This could take 5-10 minutes.
5. If it finds hundreds of .smr-d files, you are good. Note the location and use those files in Monaco.
6. If it finds ZERO results, then your Xentry installation is broken or incomplete and you need to reinstall it.

If You Do Not Have Xentry Installed At All:
Then you have two choices:

Install Xentry - Search this forum for "Xentry 2024 installation guide". Once installed and run once, all your SMR-D files will be there.
Download just the SMR-D database - Search this forum for "SMR-D database download" or "Monaco database pack". Members have shared standalone database archives that you can use without installing Xentry.

Without these files, DTS Monaco is useless. It is like having a TV remote with no batteries. The SMR-D files are the batteries.
