Ford Explorer Fault Memory Lock Active

I had a similar issue with my Explorer. The error code pointed to undervoltage in the vehicle's system. How old is your battery?

That's interesting. The battery is original, so about 5 years old. Was the undervoltage the only cause in your case, or were there other factors involved? Also, what did you do to fix it?

In my case, the undervoltage was the primary cause. Given the age of your battery, I'd suggest getting it professionally tested, but I eventually had to get the issue resolved at a workshop. Expect costs of around 240€.

Thanks for the advice! I'll get the battery tested and probably take it to a workshop as you suggested. Sounds like it could be the car electronics acting up due to low voltage, creating these fault codes.
