Diagnosis instructions

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

The ACSM control unit stores data in a non-erasable memory after a triggering of the safety system. After 3 crash signals, the data memory is full. The airbag warning lamp lights up. The ACSM control unit must be replaced.
