Lexus LS Error Memory Lock Active

I've got a 2015 Lexus LS hybrid with about 65000 km on it, and I'm running into a weird issue. The error memory lock is active and the only symptom I see is 'Error stored in the error memory'. I suspect it might be undervoltage related, but I'm not sure where to even start looking. Has anyone else experienced this?

I had something similar happen with my LS. Same fault codes about the active memory and errors stored. Did the car sit for a while unused? That's what caused mine.

That's interesting. Yes, it has been sitting unused for about two weeks. What did you do to fix it?

I didn't really 'fix' it myself. I took it to a workshop. They said the undervoltage messed with the computer system. It needed some ECU diagnostics.

Okay, sounds like I'll have to bite the bullet and take it in. Thanks for confirming it's likely the undervoltage issue, that gives me a starting point. The repair cost will probably be around 240€.
