SITUATION

After a head unit or BDC/BCP is swapped, many functions or features in the head unit are not active and the fault "B7F87A: Component Protection Active" is stored in the head unit.

CAUSE

Security functions included in the listed head units will deactivate (lock mode) all FSC* Enabling Codes if removed and swapped into a new vehicle. This security feature is called "Trusted VIN" or "Head Unit Component Protection".

*German acronym Freischalt Code

CORRECTION

All authorized FSC Enabling Codes will need to be reactivated and Head Unit Component Protection will need to be reinitialized.

Select "Vehicle Management"
Select "Vehicle Modification"
Select "Immediate Actions"
