TELE AID telediagnosis 

In the event of a service call (MB-Info or roadside assistance call), active telephone connections are interrupted. The telecommunications control unit (N123/) sends an SMS to the nearest service center and at the same time always establishes a telephone connection to the service center.

Usually, the telephone connection is established via the telephone antenna (A2/49a1) (model 220) that is located at the rear window, or via the telephone antenna (A2/22) (model 215) at the tailgate. If the telephone antenna (A2/49a1) (model 220) or the telephone antenna (A2/22) (model 215) is defective, e.g., in the event of a rollover, 2 emergency antennas are available in the rear bumper of the vehicle, which basically consist of the emergency call system antenna splitter (A2/25) and the emergency call system left backup antenna (A2/54) and emergency call system right backup antenna (A2/55). The telecommunications control unit (N112/) recognizes the failure of the antenna and subsequently actuates the emergency call system left backup antenna (A2/54) and the emergency call system right backup antenna (A2/55) automatically.
