Fault memory

Faults that occur during operation are stored in a non-volatile memory (e.g. EEPROM). The faults remain in memory even if no voltage is present at terminals 15 and 30. The fault memory is designed in such a way that the occurring faults, data source, fault type and fault deletion counter can be saved. The off-road stabilizer control module sends messages and checks the CAN drive cyclically for messages from other control modules. If no messages are received for a certain time period, a fault is stored in the fault memory.
