Geographical Usage
PSA diagnostic tools can be used across most global markets, but access to specific programming functions may depend on local compliance, SERMI implementation, or regional software restrictions.
Supported regions include:
Please check local legislation and PSA platform permissions before operating tools internationally.
Registration Requirements
To access full PSA diagnostic and programming functions—especially SERMI-restricted features—you must ensure the following business registrations are in place:
What is SERMI?
SERMI (Secure Repair and Maintenance Information) is a new EU-wide framework that regulates access to security-related vehicle functions, such as key programming and immobiliser replacements. Workshops must apply through authorised bodies and pass a compliance check to receive SERMI approval.
PSA (Stellantis) restricts certain functions unless the user has an active SERMI certificate.
Current SERMI Implementation by Country:
| Country | Implementation Date |
| Sweden | October 2023 |
| Denmark | February 2024 |
| Finland | February 2024 |
| Norway | February 2024 |
| Austria | April 2024 |
| Belgium | April 2024 |
| Germany | April 2024 |
| Luxembourg | April 2024 |
| Netherlands | April 2024 |
| Portugal | April 2024 |
| Spain | April 2024 |
| France | November 2024 |
| Italy | February 2025 |
| Poland | April 2025 |
For up-to-date SERMI application details, visit the official SERMI website.

Cost and Support
To use Diagbox for diagnostics, you’ll need to purchase a vehicle-specific access token.
Token cost: €45.80
This grants access to one vehicle VIN for 7 calendar days, including weekends and bank holidays. Tokens must be used within 12 months of purchase.
Note: You must purchase the correct token based on the vehicle brand you’re working on (e.g. Peugeot, Citroën, DS, Vauxhall).
Technical Data Access (via Servicebox Subscriptions)
These subscriptions unlock access to:
- Wiring diagrams
- TSB bulletins
- Repair manuals
- Parts catalogues
Pricing examples:
- €9.10 — 1 hour
- €31.10 — 1 day
- €3,105 — 1 year
(Daily, weekly, and monthly subscriptions also available.)
Ease of Use
- Ease of Use Rating: 7/10
Diagbox is user-friendly, with simple navigation and plenty of on-screen prompts to assist during use. - Updates are released 1–2 times per month.
- Typical update time: 30 minutes, provided the software is relatively up to date.
- Software does not need to be on the latest version to function properly, but we recommend updating a few days after each release.
Training Options
- 1-Hour Introductory Session: Ideal for new users. Covers token purchases and basic Diagbox setup.
- 2-Day PSA Classroom Training Course: A full workshop-based training covering everything from Diagbox installation, configuration, pairing, and use of SERMI-restricted functions, as well as Service box navigation.
For technicians regularly working with SERMI functions, we recommend investing in the Code Wizard Pro 2 for secure access and function authorisations.
Technical Support Options
- Dealer Tool Support Subscription – £99/month
- Vehicle Technical Support (VTS) – £125/month
Bundle both support packages for just £205/month to cover everything from tool updates to complex repair support.
Additional Products
- Code Wizard Pro 2 – Ideal for workshops frequently performing SERMI-restricted functions such as key programming, module configuration, and BSI replacement.
- S.1279 CAN Switch Adaptor – Required for full ECU communication on light commercial vehicles.
- GYSFLASH 100.12 – Maintains stable battery voltage during long programming tasks.
Optional Accessories:
While not required, a docking station or diagnostic workstation trolley can improve workflow in busy environments.
Footnote
Keep these essential notes in mind:
Stellantis is actively merging its brand portals (including Vauxhall and Fiat) into a centralised Servicebox platform. This has led to registration disruptions, particularly for workshops holding multiple logins.
Non-VAT registered businesses may experience limitations, though a new registration process for these users is being developed.
If you’re unsure how this impacts your access or usage, Maverick’s technical support team is available to assist.
