GF82.95-P-3211RTU MB-Info And Breakdown Assistance Button Group, Component Description
- with CODE (359) TELE AID emergency call system
Component Identification
Location
The MB-Info and telediagnosis button group (S93/6) is located in the center console to the right of the UPCI portable CTEL holder (Universal portable
CTEL Interface) (A34/15).
The telematics service must be authorized.
Design
The MB-Info and telediagnosis button group is designed as follows:
^
Two integrated LED's for night illumination (c. 58d)
^
Two integrated LED's for display of operating status (roadside assistance call and MB-Info call)
^
Both buttons are equipped with a control resistance located parallel to the switch contact.
Task
Either a roadside assistance call or MB-Info call be actuated with the MB-Info-and telediagnosis button group. Moreover, the current operating state is
indicated to the driver by the two integrated LEDs.
Function
In the non-actuated state electric power is supplied via the control resistors installed on MB info button group and tele diagnosis (parallel to switch
contacts).When current is flowing through the resistor, the emergency call system control unit (N123/4) knows that the voltage supply line and the
ground line are functioning properly. When one of the buttons in the MB-Info and telediagnosis button group is pressed, the control resistor is bridged by
the switch contact. The MB-Info and telediagnosis button group is read in by the emergency call system control unit over discreet lines. When one of the
buttons is pressed, the emergency call system control unit transmits the corresponding request. The emergency call system control unit then actuates the
LED for visual indication that the function has been actuated.
