Crash Entries

In the event of a crash 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 entry is stored in the fault memory with the instruction to replace the Crash Safety Module.

NOTE: The three crash entries could also be stored during the course of an accident. Each crash entry is assigned a system time. The ECU remains capable of firing even after three crash entries. The crash entries cannot be erased and serve the purpose of subsequent device diagnosis. A maximum of three crash entries can be stored. The control unit must then be replaced.
