Start Tire Change Mode IDE03331

Hello,

Attempting to replace the brake pads on a MAN TGE 2026. Unfortunately, the following error message appears: "Unknown error, cannot start."

Why?

Sure, here is the translation of the text from German to English:

"LG" can be translated as "Best regards" or "Sincerely". It is a common abbreviation for "Liebe Grüße", which means "Warm greetings" in English.

Hello,

Your vehicle uses SFD+SFD2, see:

I'm looking into what can be done.

Enabling the Vehicle Diagnostics Protection (SFD). While we are working on automating the release process, VCDS already supports the release and lock procedure using offline release tokens. The following steps are recommended when working on SFD-protected vehicles: 1. Determine which control units you need to work with, for example: - Brake electronics for work on the parking brake. · Information electronics for service reset. 2. Check if the diagnostic firewall was disabled when opening the hood. This can be done by connecting to the "Diagnostic Interface for Databus / Gateway" (address 19) and displaying the extended values for the diagnostic filter. Results like the following confirm that you do NOT need to unlock address 19 before making changes in other control units: · IDE13754-MAS16867 Diagnostic filter: Deactivation reason status → Hood open. · IDE13754-MAS16875 Diagnostic filter: Status filter status → Filter is not active. In this case, you can skip steps 3 and 4. The diagnostic firewall is already disabled. 3. If the status is "Filter active," you must request a challenge/token for the "Diagnostic Interface for Databus / Gateway" (address 19) and all additional SFD-protected ECUs that you need to work with. The results would look like this: · IDE13754-IDE04447 Diagnostic filter: Status-Function status → Function active: SFD protected. · IDE13754-MAS16875 Diagnostic filter: Status filter status → Filter active. In this case, you need to follow steps 3 and 4. The diagnostic firewall is enabled. 4. Unlock (SFD) the "Diagnostic Interface for Databus / Gateway" (address 19) and check whether the following value displays a number of minutes that is not zero. · MAS18157-MAS18164: SFD-enabled status duration for the vehicle diagnostic system to be protected → 89 minutes (this counts down to zero; after that, SFD is automatically re-locked). 5. Disable the diagnostic filter in the "Diagnostic Interface for Databus / Gateway" (address 19) - typically via the adaptation channel IDE16611-diagnostic filter: temporarily change from "active" to "inactive" - and check the following measurement value: · IDE13754-MAS16866 Diagnostic filter: Distance threshold → 20 km (this counts down from 20 km to zero; after reaching zero, the filter is automatically re-enabled). 6. Unlock (SFD) all additional SFD-protected control units on which you want to work.

Best regards, Rainer.
