Voice Activation System: Testing and Inspection

Compatibility Check For Telephone Systems With Mobile Phone Connectivity

Systems concerned: TCU (with mobile phone), ULF, ULF-SBX, ULF-SBX-H for E39/ E46/ E53/ E83/ E85/ MINI/ R56/ E65/ E60/ E87/ E90/ E70/ E71
Diagnosis of the telephone system only makes sense and is conducive to achieving objectives if the symptoms of the problem indicate there is no incompatibility caused by the mobile phone. As a rule, there is an incompatibility caused by the mobile phone if the problem occurs sporadically or only in certain locations (e.g. in the workshop) and is not reproducible.
More information on the tested mobile phones can be found in the current compatibility matrix valid for your country.












Procedure for compatibility check of the telephone system
1. Open the current market-specific / brand-specific compatibility matrix (storage location see table above).
2. Compile mobile phone data:
- Model of the mobile phone
- Read out the software version of the mobile phone (procedure: see compatibility matrix)
3. Compile control-unit data:
- Variant of control unit (TCU, ULF, ULF-SBX or ULF-SBX-H)
- Control unit software version (BMW part number)
This data is displayed at the start of the test modules "Fault pattern catalogue, telephone system". It can be also be read out at the DIS tester at Control unit functions -- Identification.
4. On the basis of the mobile phone data, the control unit data and the compatibility matrix, determine whether the present combination of BMW telephone system and mobile phone has been tested and whether any restrictions are known.

NOTE: The fault patterns and diagnosis functions offered on the DIS tester are valid for tested mobile phones. If the problem reported by the customer is described in the compatibility matrix, the instructions given in the compatibility matrix have priority.
