- Tasks of the telematics services communications module with CODE 06U (Mercedes connect me basic services) or with CODE 05U (Remote online)
- Tasks of the telematics services communications module with CODE B54 (Live Traffic Information)
Tasks of the telematics services communications module with CODE 350 (eCall Europe emergency call system)
In the emergency call system (with CODE 350 (eCall Europe emergency call system)), the telematics services communications module has the following tasks:
- Prioritization of the services in the internal arithmetic unit
- Establishing a voice connection or data link to the service provider via the emergency call system antenna (A2/52) (input and output)
- Transmitting a mute signal (mute function) to the sound system amplifier control unit (N40/3) (with code 810 (Sound system) or with code 811 (Advanced sound system)) or to the audio equipment (except code 810 (Sound system) and except Code 811 (Advanced sound system)) (output)
- Receiving the microphone signals from the audio equipment (input) during hands-free mode
- Sending audio signals in hands-free mode to the center instrument panel midrange speaker (H4/27) (output)
- Reception of GPS data (Global navigation system) for position finding from the multifunction antenna (A28/11) (with code 505 (Radio 20 NTG5 non-navigation capable), except code 357 (Map navigation), except code 522 (Audio 20 radio) and except code 531 (COMAND APS)) (input)
- CAN communication (CAN D) with the electronic ignition lock control unit (N73) via the diagnostic CAN
In the emergency call system (with CODE 350 (eCall Europe emergency call system)), the telematics services communications module can receive the following CAN signals via the electronic ignition lock control unit, for example:
- Status of "circuit 15R" from electronic ignition lock control unit as trigger signal for self-diagnosis of emergency call system
- Cyclic standby signal ("vital sign") of the supplemental restraint system control unit (N2/10) as a check signal
- Crash signal from supplemental restraint system control unit as trigger signal for the automatic emergency call
- "Central locking emergency opening" signal from the SAM control unit (N10) as a redundant trigger signal for the automatic emergency call
- Control signal of the emergency call system button (S93/3s2) from the SAM control unit (manual emergency call)
- Control signals of the button groups on the multifunction steering wheel from the instrument cluster (A1) (e.g. volume control, muting, establish or disconnect connection)
- Control signals from the touchpad (A105) (with CODE 531 (COMAND APS)) or from the Audio/COMAND control panel (A40/9)
- Signals of the steering wheel angle sensor (N49) from the steering column tube module control unit (N80), for position finding
- Wheel speed signals from the Electronic Stability Program control unit (N30/4), for position finding
- Position data from the audio equipment (with CODE 357 (Card navigation), with CODE 522 (Audio 20 radio) or with CODE 531 (COMAND APS)), for position finding
In the emergency call system (with CODE 350 (eCall Europe emergency call system)), the telematics services communications module can transmit the following CAN signals, for example:
- Actuation of the light-emitting diode in the emergency call system button to the SAM control unit (for status indication)
- Check signal for emergency call system button to SAM control unit (for self-diagnosis of emergency call system)
- Display messages for display on the Audio/COMAND display (A40/8) to the audio equipment
Tasks of the telematics services communications module with CODE 06U (Mercedes connect me basic services) or with CODE 05U (Remote online)
The telematics services communications module has the following tasks with CODE 06U (Mercedes connect me basic services) and with CODE 05U (Remote online):
- Establishing a voice or data link to the service provider via the emergency call system antenna (input and output)
- Transmission of a mute signal (mute function) to the sound system amplifier control unit (with code 810 (Sound system) or with code 811 (Advanced sound system)) or to the audio equipment (except code 810 (Sound system) and except code 811 (Advanced sound system)) (output)
- Receiving the microphone signals from the audio equipment (input) during hands-free mode
- Sending audio signals in hands-free mode to the center instrument panel midrange speaker (output)
- Reception of GPS data for position finding from the multifunction antenna (with code 505 (Radio 20 NTG5 non-navigation capable), except code 357 (Map navigation), except code 522 (Audio 20 radio) and except code 531 (COMAND APS)) (input)
- CAN communication over the diagnostic CAN to the electronic ignition lock control unit
With CODE 06U (Mercedes connect me basic services) or with CODE 05U (Remote online), the telematics services communications module can receive the following CAN signals via the electronic ignition lock control unit, for example:
- Control signals of the button groups on the multifunction steering wheel from the instrument cluster (e.g. volume control, muting, establish or disconnect connection)
- Control signals from the touchpad (with CODE 531 (COMAND APS)) or the Audio/COMAND control panel
- Signals of the steering wheel angle sensor from the steering column tube module control unit, for position finding
- Wheel speed signals from the Electronic Stability Program control unit, for position finding
- Position data from the audio equipment (with CODE 357 (Card navigation), with CODE 522 (Audio 20 radio) or with CODE 531 (COMAND APS)), for position finding
With CODE 06U (Mercedes connect me basic services) or CODE 05U (Remote online), the telematics services communications module can transmit the following CAN signals, for example:
- Display messages for display on the Audio/COMAND display to the audio equipment
Tasks of the telematics services communications module with CODE B54 (Live Traffic Information)
During navigation with real-time traffic data (with CODE B54 (Live Traffic Information)), the telematics services communications module has the following tasks:
- The telematics services communications module receives real-time traffic data from the service provider via the emergency call system antenna and forwards this via a USB connection (Universal Serial Bus) to the audio equipment, and via the USB splitter (A2/128) in vehicles with code 522 (Audio 20 radio).
- The telematics services communications module receives position data from the audio equipment via a USB connection or via the USB splitter in vehicles with code 522 (Audio 20 radio), links the data with the data of the integrated positioning module and transmits the resulting position data to the service provider via the emergency call system antenna.
