Mercedes me services - activation not possible Notes: - The event code \"B16AC00 - The configuration of the SIM card is erroneous\" is active and stored - The head unit shows no internet connection Cause The RAMSES module may be faulty. This fault profile can be recognized as follows: With XENTRY Diagnosis, enter the \"ACTUAL values\" menu of the RAMSES control unit and read out the values with position 175 and 727. ACTUAL values in the event of a fault: Type of mobile service (position 175): No reception Operating mode (position 727): Ready mode Remedy If B16AC00 is permanently active and saved and position 175 is no reception and position 727 is ready mode, it is highly likely that the communication module is faulty. In this case, an initial start up must be carried out. If the problem persists even after an initial start up, please create a TIPS case.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11030159-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11030159-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11030159","components":[{"id":"electrical","name":"Electrical
