You need to inspect the data stream of your charging system. The Voltage regulator is now part of the Engine Computer, so first check your Alternator. It could be a bad rectifier, brushes, connections etc.
Unchanging this same issue I've changed my battery with a new one and replaced the alternator what could be the problem
I had the same problem, charger system failure. Check the fusible link wire between the starter and the alternator.
