A licence is part of a diagnostic tool’s configuration, not simply an annual renewal fee. Before buying, match the package to your device, vehicles and workshop procedures. A vehicle brand name or a long feature list does not confirm support for every operation.
What does the licence include?
Separate the right to use software, the update period and access to online services. A package may cover particular brands, functions or protocols, but terms differ between manufacturers and models. Request the included functions and accessories before activation.
Match the package to workshop tasks
Name the actual work: service resets, active tests, coding, IMMO or ECU/TCU operations. For programming, check the control unit, OBD, bench or boot procedure, required accessories and any Master/Slave configuration. Support for a vehicle brand alone is not enough.
Renewal and use after expiry
Check the start date, duration and renewal process. Some models retain certain functions from the last installed version, while particular online services require an active subscription. Do not assume either a complete shutdown or permanent access to every function; request the terms for your device.
SGW and additional access
Check FCA/SGW, VAG SFD, Renault Gateway, tokens and OEM accounts separately for the tool, market and task. Support for a protocol such as DoIP or CAN FD does not replace required authorization. Confirm the price, duration and activation process for each access option before ordering.
Information to check before ordering
Send the information needed for verification. Do not send account passwords.
- Exact tool model, serial number and current licence status.
- Vehicle make, model, year, engine and control-unit identification.
- Required function, adapters and connection method.
- Confirmation of total price, taxes, activation and included support.
Original software and technical support
Use a verifiable official activation channel and keep the invoice, licence confirmation and registration details. When reporting a problem, record the software version and error message. A valid licence does not replace expertise, a stable power supply, backups where required or the manufacturer’s instructions for the procedure.
Frequently asked questions
Is an annual update the same as every additional licence?
No. Updates, function packages and protected access may have different terms. Check the contents of the specific offer.
Can a licence be transferred to another device?
This depends on the manufacturer, licence type and registration. Request written confirmation of transfer terms before buying or changing devices.
Does a licence guarantee support for all vehicles?
No. Confirm the exact vehicle model, control unit and function, along with the necessary equipment and authorization.
