General telematics services function requirements
Circuit 30g ON
Transport mode not active
The vehicle owner is registered and authorized at the Service Center.
No prioritized service (emergency call (manual or automatic), MB information call, breakdown assistance) is activated.
General telematics services
For comfortable mobility planning on electric vehicles, the customer has the option of calling up vehicle data via the Internet and making settings via a vehicle-specific Web site, the "Vehicle Homepage". Position-dependent control and monitoring of the charging processes in particular are made possible by this. The "Vehicle Homepage" is made available by the service provider. The telematics services that can be performed via the "Vehicle Homepage" include the following functions, e. g.:
Display of charge level and expected battery charging duration
Configuration and illustration of the pre-entry climate control
Pre-air conditioning
Illustration of the estimated range
Illustration of driving profiles (evaluations and statistics)
A gradual expansion of the functional scope is planned.
The processing of the telematics services includes the following procedures:
Communication between vehicle and "Vehicle Homepage" via service provider
CAN communication between the emergency call system control unit and additional vehicle components
Communication between vehicle and "Vehicle Homepage" via service provider
As soon as the user has successfully called up the "Vehicle Homepage", he/she can exchange data with the vehicle (e. g. call up information and make settings) via a mobile radio connection secured by the service provider.
The vehicle receives and transmits the signals via the following route:
Multifunction antenna
Emergency call system control unit (with code 348 (Emergency call/Assist system)) or telematics services communications module (with code B57 (COM MODULE battery level))
Model 222.163
up to model year 2017
with code 348 (Emergency call/assistant system)
except code 05U (Remote Online)
except code 06U (Mercedes connect me standard services)
Model 222.163
up to model year 2017
with code B57 (KOM Module battery charging)
except code 05U (Remote Online)
except code 06U (Mercedes connect me standard services)
In the event of a failure or poor reception of the multifunction antenna (e.g. defect due to rollover), the emergency call system control unit (with code 348 (Emergency call/assist system)) or the telematics services communications module (with code B57 (COM module battery level)) automatically sends and receives the signals via the left emergency call system antenna and the right emergency call system antenna by way of the emergency call system antenna splitter.
CAN communication between the emergency call system control unit and additional vehicle components
When data relating to the charging processes is exchanged, the emergency call system control unit (with code 348 (Emergency call/assist system)) or the telematics services communications module (with code B57 (Battery charge level COM MODULE)) communicates via the hybrid CAN with the power electronics control unit and the battery management system control unit.
During pre-entry climate control, the emergency call system control unit (with code 348 (Emergency call/assist system)) or the telematics services communications module (with code B57 (COM MODULE battery level)) exchanges data as follows:
Hybrid CAN
Powertrain control unit
Chassis FlexRay
Electronic ignition lock control unit
Interior CAN
Climate control control unit
The settings made in the "Vehicle Homepage" that are relevant for what is displayed in the instrument cluster are transmitted via the following route:
Emergency call system control unit (with code 348 (Emergency call/assist system)) or telematics services communications module (with code B57 (Battery charge level COM MODULE))
Hybrid CAN
Powertrain control unit
Chassis FlexRay
Electronic ignition lock control unit
User interface CAN
