Mercedes me services - activation not possible. Notes: - In the quick test, no fault code and no event code is stored in the RAMSES control unit (N112/2). The SIM card may be defective. A defective SIM card can be identified as follows: With XENTRY Diagnosis, open the \"ACTUAL values\" menu of the RAMSES control unit and read out the values for \"EUICC, ICCID, IMEI, IMSI\". ACTUAL values in the event of a defect: 1. EUICC:null 2. ICCID: null 3. IMEI: null 4. IMSI: null If all the values for \"EUICC, ICCID, IMEI, IMSI\" = null, then it is highly likely that the SIM card inside the RAMSES control unit is defective. Recommissioning the RAMSES control unit may rectify the problem. If the problem is still present after the recommissioning, then the RAMSES control unit must be replaced. In this case, please create a TIPS case and forward it to HQ. The part is required for analysis. Information on the return delivery of the module will be communicated via TIPS case.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244776-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244776-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10244776","components":[{"id":"electrical","name":"Electrical
