GF82.95-P-2015SXR Display Of TELE AID Status, Function
- Model 221
- with CODE (389) Mobile phone preinstallation with universal interface, USA/Canada

The state display in the SOS pushbutton switch (S93/3) serves for checking the function of the Telematic Alarm Identification on Demand (emergency call system) (TELE AID).

Switch-on characteristics
Every time TELE AID is switched on, the state display of the SOS pushbutton switch comes on for 4 s and thus signals TELE AID readiness. If there is no fault, the state display of the SOS pushbutton switch goes out after 4 s.

Fault behavior
A TELE AID error is present if the state display of the SOS pushbutton does not go out 4 s after switching on or if it comes on at a later time. In the event of a fault, a fault message appears in the multifunction display (A1p13) of the instrument cluster (A1).

Triggering a TELE AID telediagnosis
When a TELE AID telediagnosis has been triggered, the state display of the SOS pushbutton flashes at a frequency of approx. 1 Hz. In addition, a state message appears in the multifunction display of the instrument cluster and in the COMAND display (A40/8). If it was not possible to carry out TELE AID telediagnosis, the state display of the SOS pushbutton switch is illuminated without interruption. Furthermore, a fault message appears in the multifunction display of the instrument cluster. When a voice connection is established, the state display of the SOS pushbutton switch returns to the status it was in before a TELE AID telediagnosis was triggered. A status message appears in the instrument cluster of the multifunction display and in the COMAND display.

If the TELE AID is in diagnostic mode, the state display of the SOS pushbutton switch also starts to flash on and off.

Continuous illumination of the state display of the SOS pushbutton switch can have the following causes:
^ Power supply too low
^ No or wrong subscriber identification module (SIM) card installed
^ Communication with restraint system control unit (N2/7) interrupted
^ Communication error with the ESP control unit (N47-5)
^ Error in SOS pushbutton switch
^ Error in Global Positioning System (GPS) antenna system
^ Reception interference (emergency call system left backup antenna (A2/54), emergency call system right backup antenna (A2/55) or telephone and GPS roof antenna (A2/49) (on model 221) or telephone and GPS antenna (A2/49) (on model 216)
^ Vehicle is not authorized or is in the progress of authorization
^ Memory fault in emergency call system control unit (N123/4)
^ Personal Identification Number (PIN) has not been stored in the emergency call system control unit by the user or at the factory
^ Integrated telephone components in emergency call system control unit faulty

The emergency call system control unit can be coded using STAR DIAGNOSIS so that despite missing authorization neither the state displays of the SOS pushbutton switch light up, nor the corresponding messages are shown in the instrument cluster of the multifunction display and in the COMAND display. Deactivation of the status display must be confirmed by the customer to the dealer, in writing, on a preprinted form.

Component Identification:

The state displays provide the driver with an overview of the TELE AID status. This can be seen by the state display of the SOS pushbutton switch either flashing on and off or being illuminated continuously.
