4.2.6. Crash entries

In the event of a collision where one or more actuators are triggered, a crash entry is stored in a non-erasable memory. After three crash entries, a non-erasable fault memory entry is stored with the instruction to replace the Crash Safety Module.

NOTE: The three crash entries can also be stored during the course of an accident. Each crash entry is assigned a system time.
The electronic control unit remains capable of firing even after three crash entries. The crash entries cannot be erased and are used to diagnose the device. A maximum of three crash entries can be stored. The control unit must then be replaced.
