Function requirements, general 

IMPORTANT The triggering of correspondingly listed vehicle-related services is described in greater detail in each respective subfunction.

Status indication of TELE AID, general 

The red light emitting diode (LED) integrated into the SOS push button (S93/3) is used for displaying the following actions:

IMPORTANT Faults in the TELE AID system are also displayed in the multifunction display (A1p13) of the instrument cluster (A1), depending on the fault type.

The LED integrated into the MB-Info and breakdown assistance button group (S93/6) flashes when an MB-Info call or the breakdown assistance is active.

The execution of the vehicle remote door unlock is displayed by a message in the instrument cluster.

The status indications of the TELE AID system are made up of the following subfunctions:

IMPORTANT The SOS push button is integrated into the overhead control panel control unit (N70).

TELE AID system status in quiescent state function sequence 

As soon as the status Circuit 15R On is achieved, the red LED integrated into the SOS push button lights up during the self-test of the emergency call system control unit. Actuation is accomplished by the emergency call system control unit via a discrete line.

This indicates a self-test and testing of the following TELE AID system states:

IMPORTANT The emergency call system control unit receives status Circuit 15R On via diagnostic CAN (CAN D) from the EZS control unit.

Communication from the restraint systems control unit ("LIFE signal" every 500 ms) with the emergency call system control unit takes place discretely.

The following components are each tested via a direct line:

If no fault is present, the red LED integrated into the SOS push button goes out after approx. t = 3.5 s and thereby signals TELE AID system operational readiness.

If a fault is present, the red LED integrated into the SOS push button is permanently actuated by the emergency call system control unit via a direct line. Depending on the fault type, a message is displayed in the COMAND operating, display and controller unit and in the multifunction display in the instrument cluster and finally stored in the emergency call system control unit's memory.

The message is displayed in the COMAND operating, display and controller unit and in the instrument cluster by the emergency call system control unit via diagnostic CAN to the EZS control unit and then via interior CAN (CAN B).

TELE AID system status function sequence for TELE AID emergency call 

After triggering an automatic or manual TELE AID emergency call, the emergency call system control unit intermittently (flashing) actuates one of the two red LEDs integrated into the SOS push button via a direct line.

TELE AID system status for breakdown assistance function sequence 

After triggering the breakdown assistance using the MB-Info and breakdown assistance button group, the emergency call system control unit intermittently (flashing) actuates the LED integrated into the MB-Info and breakdown assistance button group directly via a direct line.

TELE AID system status for MB-Info call function sequence 

After triggering the MB-Info call using the MB-Info and breakdown assistance button group, the emergency call system control unit intermittently (flashing) actuates the LED integrated into the MB-Info and breakdown assistance button group directly via a direct line.

TELE AID system status for vehicle remote door unlock function sequence 

After triggering the remote door unlocking by means of a telephone call to the service center, the emergency call system control unit displays the message via the following route in the COMAND operating, display and controller unit and in the instrument cluster: via diagnostic CAN to the EZS control unit and then via interior CAN.
