Inconsistent long term RAM data.
No action is needed if DTC is set a few times (1-5). The system should work normally after reset, the DTC is only activated to track the reset cause. However, If set frequently: • Check electrical installation in vehicle for non-certified third party equipment(*) and disconnect these. • Check for available software updates/campaigns. • Thereafter, replace ECU if problem remains (*) The sensitivity, for equipment with high EMC radiation, is increased in an EMC emitting environment. This could for example be radar stations (airport/military), electric distribution plants, electrical switch towers, transformer stations, steel works, "electric" welding, etc.
What you'll see
No driver-visible symptom recorded.
System reaction
A software reset is performed. Thereafter the system should work normally.
Diagnostic depth
Memory used to store configuration data is inconsistent/corrupted.
• Exposure to extensive electro-magnetic radiation • Software flaws • ECU hardware error.
