hi,
that code means there may be a short or fault in a wiring harness or an issue with the alternator/regulator. could be a faulty battery cable or ground/negative cable. have you had your charging system tested? have you visually inspected your wiring in the engine room to see if anything is damaged? you could be losing continuity in a wire harness that su causing this fault to happen intermittently.
can you reproducde the issue or is it just random? if random, are you driving over a bump in the road, or making a sharp turn or accelerating hard?
how did you get this code? do you have a code reader or was it a mechanic?
did you buy this car new or used? have you had it a while? did this just start happening at once or gradually? did you do anhy maintanece on it prior to this hapening? added/removed anything on the car that could be affecing this?
the more you tell us over the internet, the better someone can help you. we cant see your car and rely on what you say for context.
