29.05.2024 - EPT: The new tool for parameterization for trucks
More Information

The Expert Parameterization Tool (EPT) is a new, web-based application that will be used to carry out manual truck parameterization in workshops in the future. The tool can only be used for trucks. Buses are not supported.

In order to comply with the new "SUMS" regulations, the parameterization process has been further developed. Thanks to EPT, the parameterization can be prepared before the workshop visit and the vehicle’s time spent in the workshop can be minimized.


In order to trigger the parameterization and bring it to the vehicle, Daimler Truck Diagnostics is still required as a physical connection.

To use EPT, the diagnostic flash role "DTDIAG.TRUCK.WORKSHOP.INITIALSTARTUPDIAGNOSTICS.ISP" is sufficient and is already a prerequisite for all other functionalities of parameterization and flashing.

How to use EPT:

The switch to EPT will start with the new ODX ECUs and will then be successively made available for the old ECUs as well. For more information please refer to the  EPT Quick Guide (PDF).

In the transition phase, mixed parameterizations (DTD & EPT) may exist on a vehicle – especially in the case of body builders.

The familiar parameterization via DTD is no longer possible after the respective control unit has been converted.

You can reach the EPT site in the following ways:

  • Via the direct link:  Daimler EPT
  • Via the link in DTD in the info screen below "Adjustments"

13.03.2024 - XENTRY Truck TIPS – Important Migration Information
More Information

XENTRY TIPS becomes XENTRY Truck TIPS. The application is now being taken over by Daimler Truck AG. XENTRY Truck TIPS is a 1:1 copy of the current XENTRY TIPS system, all truck-relevant functions remain available and no additional training is required.

The global rollout will take place on 25th of March 2024. All XENTRY Truck TIPS user rights, licences and settings are transferred automatically, there is no action required.

05.03.2024 - Daimler Truck Diagnostics Flash and FBS rights
More Information

As of March 2024, there will be an updated scheme for ISPs to request Daimler Truck Diagnostics Flash and FBS4 base rights rights separately. These changes will apply for new ISP requests. Existing ISP flash and FBS rights will remain active and are migrated automatically.

Until now, the DT DIAG Flash User ISP role enabled initial startup routines especially with key calculation for powertrain control units, Software reprogramming, parameterization, and base rights FBS4 with component replacement and blocking key chains.

The base rights FBS4 (with component replacement and blocking key chains) for ISPs will no longer be included into the DT DIAG Flash User ISP role. ISPs can now request base rights FBS4 as well as FBS4 extended rights (for key programming and key track enabling) via the user application form ‘FBS4 Online Services Daimler Truck AG’.

Please note, that it is mandatory to provide the training certificate T1938F or T2226W (handling of the Daimler Truck Diagnostics processes and the proper awareness of TRP (theft-relevant parts) including vehicle keys) to successfully receive the FBS4 extended rights.

25.01.2024 - Important notes on the new VCI firmware for Daimler Truck Diagnostics
More Information

For Daimler Truck Diagnostics, a new firmware (version 1940) for the VCI will be available with immediate effect.

The firmware update will be rolled out in three waves. The first wave will be available to the Daimler Truck Diagnostics Kit 1, the second to the VCIs of the Platform Independent Systems and last, from February 5th the migrated XENTRY Diagnosis Kit 3 and 4.

The update is necessary to continue working with the VCI.

Please note:

This firmware update sets a "marker" in the VCI, which configures the VCI as a Daimler Truck VCI. Therefore, if you install the Daimer Truck Diagnostics VCI firmware on a XENTRY VCI:

IMPORTANT: No further car and VAN diagnostics can be carried out afterwards

A recovery to XENTRY VCI firmware is not technically possible! Once the update has been installed, the VCI can no longer be reverted to the XENTRY Diagnosis firmware.

IMPORTANT: Please make sure that only those VCIs that are to be used for Daimler Truck Diagnostics in the future receive the firmware update.

30.06.2022 - Multi-Factor Authentication (MFA)
More Information

per la messa in servizio, la programmazione e la codifica di centraline di comando antifurto (Driving Authorization System 4 / FBS 4), oltre al login personale con nome utente e password sarà necessaria un'autenticazione a due fattori, come ad es.:

  • app per smartphone o
  • chiave di sicurezza USB

Verificare se nella propria attività lavorativa quotidiana è possibile eseguire l'autenticazione tramite smartphone e, in tal caso, installare un'app di autenticazione.  

Se nella vostra azienda non è consentito l'utilizzo di uno smartphone, richiedete una chiave di sicurezza USB a un rivenditore di articoli di elettronica o direttamente a un chiave di sicurezza USB produttore (importante: la chiave di sicurezza USB deve supportare lo standard FIDO2).  

Tenete presente che la consegna può richiedere diverse settimane, a seconda del fornitore.  

Per assistervi nella configurazione dell'autenticazione a più fattori, forniamo unaHelpCard compatta da scaricare.

Per assistenza tecnica avanzata in caso di problemi con l'applicazione, creare un ticket XSF; in alternativa, se non si dispone dell'accesso XSF, inviare un'e-mail a:
