Corsa Fault Memory Lock Active

My 2020 Vauxhall Corsa (electric engine) is throwing a weird error. I scanned it and it says 'Fault memory lock active'. The only symptom is 'Error stored in the error memory' in the ECU. Any ideas?

I had a similar thing happen in my Corsa, though it's an older model. Did the diagnostic tool mention anything about undervoltage? An undervoltage situation in the computer system might be the cause for the fault codes.

Undervoltage, huh? The scan tool didn't say anything specific about voltage. How did you figure out it was undervoltage on yours? Any specific control unit?

The garage guys found some ECU fault codes linked to low voltage. They mentioned it could lock the active memory. After checking it, they told me I needed a reset.

I'll get the dealership to check the undervoltage and the associated errors. Apparently, the repair will cost about 240€. Fingers crossed!
