Actuation 

The telediagnosis call can be triggered by pressing the telediagnosis button (with a wrench symbol on it) (S93/6s2) in the MB-Info and telediagnosis button group (S93/6). Pressing the telediagnosis button for longer than 0.5 s activates the telediagnosis call. Activation of the telediagnosis call is indicated by the light emitting diode (LED) integrated in the telediagnosis button flashing on and off. Regardless of the request, the telediagnosis button is read in by the emergency call system control unit (N123/4) over a discrete line. The emergency call system control unit automatically sets up a voice connection to the Customer Assistance Center (CAC).

Telediagnosis call (roadside assistance call) 

When the telediagnosis button is pressed, an SMS (not with Advanced Mobile Phone System (AMPS)) is automatically sent to the CAC. Data, which are automatically transmitted in the event of a telediagnosis, are:

• Vehicle position
• Customer identification data
• Vehicle identification data
• Condition data
• Fault code

Transmitting a telediagnosis telegram 

In the event of a service call (telediagnosis), active telephone connections are interrupted. The emergency call system control unit transmits an SMS (not with AMPS) to the closest CAC and establishes a telephone connection to the CAC.
