Complaint:

"SOS - Service not activated" message in instrument cluster.
MB Apps, Internet Radio, LiveTraffic Information, iCall/S24h-Call nonfunctional.
Note: In the N112/9 control unit for telematics services (HERMES) the event code B15CE00 is active and stored.

Cause:

The vehicle's backend "over-the-air" registration (OTAR) has failed or was not completed successfully.
This complaint can have several causes.
Note: The attachment includes a simplified depiction of the OTAR process.
The basic requirements can be checked using the control unit log from the N112/9 control unit for the telematics services (HERMES).
-1.) The basic requirements are not given when:
1.a) Comparison of control unit log and Vedoc: Required SIM card values (ICCID, IMEI, IMSI, SNR HU) are not documented in VeDoc or documented incorrectly. (See attachments "SIM Card Data" and "SIM Card Data in Vedoc")
1.b) "Operating Mode" is not in "Provisioning Mode". (See attachment "SIM Card Data")
1.c) The signal strength of the mobile network is 0%. (See attachment of "GPS Data and Mobile Network Information")
1.d) No visible GPS values in control unit log (empty values for date and time). (See "GPS Data and Mobile Network
Information")
1.e) Invalid/incorrect GPS values visible in control unit log (values present, for date and time, but they are incorrect).
(See "GPS Data and Mobile Network Information")
1.f) Initial authorization certificate invalid. (See attachment "SIM Card Data")
-If all basic requirements are given, the cause can be further restricted by reading out the "Status of registration". (See
attachment "Status of registration in XENTRY Diagnosis")
2.) Registration errors at mobile phone service provider's (DC.20- DC.27)
3.) Error when replacing certificate (CEP.30 - CEP.3C)

Remedy:

Note: For registration with the Backend, it must be ensured that the vehicle has adequate GSM and GPS reception.
-1.a) Perform new initial startup of N112/9 control unit for telematics services (HERMES) and head unit (A26/17 or
A40/3 oder A2) using XENTRY Diagnosis.
1.b) "Transport Mode", "Supplier Mode" or "Out of Service Mode": Perform new initial startup of N112/9 control unit
for telematics services (HERMES) using XENTRY Diagnosis.
Extra work for "Out of Service Mode": If the new initial startup is not productive, please contact Verizon Dealer Support and make sure that they have activated the SIM card. Following this, repeat the initial startup procedure for the
N112/9 control unit for the telematics services (HERMES) using XENTRY Diagnosis to switch the "Operating Mode"
into the "Provisioning Mode".
1.c) Perform a short test drive (approx. 10 min), while doing so make sure that the GSM and GPS reception level is
sufficiently high.
1.d) Check the head unit (A26/17 or A40/3 or A2) for GPS antenna fault codes and process them if necessary. If there
are no faults, perform a short test drive (approx. 10 min). While doing so make sure that the GSM and GPS reception
level is sufficiently high.
1.e) Creation of a PTSS case. Attach a control unit log of the N112/9 control unit for the telematics services (HERMES) and the head unit (A26/17 or A40/3 or A2) to the PTSS case.
1.f) Reset the initial authorization certificate of the N112/9 control unit for the telematics services (HERMES). (See attachment "Reset initial authorization certificate of HERMES")
-2.) Please contact Verizon Dealer Support and notify them of the registration status. The following information for the
control unit N112/9 in question requires: ICCID, IMEI, IMSI, IMSISDN, serial number. Support will contact Verizon Wireless to rectify the complaint.
-3.a) CEP.30, CEP.31, CEP.32, CEP.35, CEP.37, CEP.38, CEP.39, CEP.3A: Creation of a PTSS case. Attach a control unit log of the N112/9 control unit for the telematics services (HERMES) to the PTSS case.
3.b) CEP.33: Temporary backend malfunction. Wait for 24 hours then assess the complaint again.
3.c) CEP.34, CEP.36, CEP.3B, CEP.3C: Use XENTRY Diagnosis to perform a new initial startup of the N112/9 control unit for the telematics services (HERMES) and the head unit (A26/17 or A40/3 or A2). Then reset the initial authorization certificate of the N112/9 control unit for the telematics services (HERMES) (see attachment "Reset initial authorization certificate of HERMES"). A memory in the Daimler Vehicle Backend enables the registration process to be
delayed by 24h. Please wait 24 hours and perform a test drive. If, after this, registration is still not successful please
create a PTSS case. Attach a current quick test along with an up-to-date control unit log of the N112/9 control unit for
the telematics services (HERMES) to the PTSS case.
-4.a) TOC.40 to TOC.46: Creation of a PTSS case. Attach a control unit log of the N112/9 control unit for the telematics services (HERMES) to the PTSS case.

4.b) TOC.47: Using XENTRY Diagnosis perform a new initial startup of the N112/9 control unit for the telematics services (HERMES). Then reset the initial authorization certificate of the N112/9 control unit for the telematics services
(HERMES) (see attachment "Reset initial authorization certificate of HERMES"). A memory in the Daimler Vehicle
Backend enables the registration process to be delayed by 24h. After 24h perform a brief test drive. If, after this, registration is still not successful please create a PTSS case. Attach a current quick test along with an up-to-date control
unit log of the N112/9 control unit for the telematics services (HERMES) to the PTSS case.
