Suburban Fault Memory Lock

I'm experiencing a peculiar issue with my 2023 Chevrolet Suburban diesel. The system indicates a 'Fault memory lock active' state. The primary symptom is simply an error stored in the error memory. I suspect it might relate to car electronics or the computer system. Mileage is currently at 38278 km. Any thoughts before I delve deeper into automotive diagnostics?

A 2023 Chevrolet Suburban diesel is experiencing a 'Fault memory lock active' error, suspected to be related to car electronics or the computer system. A possible cause identified is undervoltage, which might be locking the memory. A suggested solution is to have the vehicle checked at a workshop, where re-flashing the computer systems and checking the alternator could resolve the issue. The problem was confirmed and resolved at a workshop, likely due to undervoltage, with the error cleared successfully.

Interesting. I've seen something similar with my Suburban. Have you checked for any signs of undervoltage? In my case, it was like a flickering lightbulb – present, but dimming unexpectedly. That undervoltage condition might be locking your memory.

Thanks for the tip. That's helpful. When you experienced this undervoltage, did it immediately trigger the 'fault memory lock,' or did other anomalies precede it? I'm trying to gauge the timeline to better understand the root cause.

For me, the memory lock seemed to be the culmination of the issue, not the start. I'd suggest taking it to a workshop, because it sounds like a similar issue. In my case, they re-flashed my computer systems and checked the alternator.

I appreciate the advice; undervoltage leading to the fault memory lock makes sense. I took it to a workshop; they identified the issue, likely undervoltage as mentioned and cleared the error. The final repair cost was 240€. Thanks again for the help!
