SummaryMercedes me connect services inoperative (me-Call, Remote Status, etc.). 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.

SummaryIn the instrument cluster, the symbol for "12 V battery" and the message "Switch on vehicle" may sporadically be displayed. As a consequence of this, the fault codes B 1 FCB97 (=> N73/3) and U 116000 (=> N73/3*1) are stored in the fault memory. In the subsequent analysis of the 12 Von-board electrical system data, the following parameters are conspicuous (see picture 1 in the attachment): ⢠Charge balance negative when stationary. ⢠Interior CAN bus is awake for an unusually long time. ⢠12 V battery SOC (state of charge) during subsequent engine start is 45% or less. NOTE: Once the 12 V battery SOC has exceeded 50% for the first time, the symbol and the message in the instrument cluster disappear again. The door control unit (N69/x) may sporadically keep the interior CAN bus awake. NOTE: Exclusively door control units with the HW item numbers A2239019917 and A2239010018 can be affected. Open a TIPS case and include the following: 1. Initial Quick Test 2. N73/3 EZS CUL 3. N73/3*1 EZS CUL 4. Date and time of occurrence
