The control module is mounted in the center of the vehicle on the driveshaft tunnel below the center console. The control module contains the processing electronics (Smart Technology) for triggering of all air bags and pyrotechnic devices installed in the vehicle. Two electronic deceleration sensors are installed in the module for crash or impact detection.
The system is recognized by the 50 pin connector on the control module. There are two manufactures of MRS III systems: Bosch and Temic. Definitive verification of the installed system is carried out through the identification pages of the diagnostic testers.
The MRS III is connected to the K-bus (except Z3).
