TELE AID control unit, function - GF82.95-P-4100-04PMU

The emergency call system control unit (N123/4) operates with its own microprocessor. Here, a differentiation is made between the 2 subareas of the telephone module and the navigation module. The emergency call system control unit (N123/4) centrally processes all the important data required for a Telematic Alarm Identification on Demand (emergency call system) (TELE AID) emergency call. With the aid of the installed navigation module, it calculates the vehicle position and generates an emergency call telegram as an SMS in the event of an emergency call.

The crash data is received by the restraint systems control unit (N2/7) via a serial interface.

The emergency call system control unit (N123/4) has a diagnosis capability. The fault memory can be read out using the STAR DIAGNOSIS via the Controller Area Network (data bus/CAN bus) (CAN) diagnosis and the central gateway control unit (N93) (up to 30.11.04) or the EIS control unit (N73) (as from 1.12.04).
