Diagnosis instructions

NOTE: After 3 crash signals with triggering of the safety system, replace the MRS control unit.

The MRS control unit stores data in a non-erasable memory after a triggering of the safety system. The data is relevant to accident research (no access for service). After 3 crash signals, the data memory is full. The airbag warning lamp lights up. The MRS control unit must be replaced.
