Fiat 500 Electric Fault Memory Lock

Help! My 2021 Fiat 500 Electric is throwing a fit! I'm getting an error saying 'fault memory lock active'. All I know is there's an error stored in the error memory. Anyone seen this before? Is my little guy doomed?

A 2021 Fiat 500 Electric displayed an error message indicating a 'fault memory lock active,' suggesting a critical error stored in the Engine Control Unit (ECU). This issue was potentially caused by undervoltage affecting the vehicle's computer system. The recommended solution was to seek professional diagnosis and repair at a workshop, which successfully resolved the problem.

Did this summary help you solve your problem?

I also own a Fiat 500, and I experienced a similar issue not too long ago. If I understand correctly, the fault memory lock being active essentially means that the Engine Control Unit (ECU) has detected a critical error and has locked the memory to prevent further data corruption. Have you considered the possibility of undervoltage affecting the vehicle's computer system?

Undervoltage? Hmm, hadn't thought of that. Is that a big deal? What did you do about it?

Confirming that, it can be quite detrimental to the control unit if the undervoltage is significant. Considering the potential severity of ECU faults and active memory locks, I would suggest a professional diagnosis and subsequent remedy at a workshop. That is the most safe way.

Thanks so much! Dropped it at the workshop, and turns out it was indeed undervoltage causing the memory lock. Cost me 240€, but at least it's fixed!
