I just recently had to do this as well, wound up being the battery current sensor, even though no codes were being displayed, the car was having a noticeable problem everytime it dropped into low charge mode. I wound up changing the parameters in HPTuners so that the duty cycle of the alt never drops below 50%.
I have a whole PDF on how the charging system works, but needless to say there are only really three things that control it, the current sensor, and the ECM/BCM.

The tuner can’t only handle ecm tuning but I’m sure it’s between BCM AND ECM and it’s when I CAIN the car.
Car started doing it before any mods so I replaced battery OPTIMA RED 815cca and alternator and a 170amp with clutch.
ok for a while then one arvo gave her some and later alternator/battery cleared then I’ve crammed etc.
first few tunes ok then the last tune I was to wind her out redline and it was on and off a lot etc.
Seeing as I’m not working on anyone else’s I just want to not spend K’s on my own car and being there when parts and software would be the new earn to limit working on them.
Could I get a copy of Schematic and how it’s working talking ?
And if you know any apps software that can remove codes not just read ECM and what’s out there that can read and talk to BCM + change values,
I haven’t got $$$ to throw away on bodgy apps or software.
Or thousands for a shop software even plenty of Auto elects steer clear of this/ too much when there’s heaps of easier work out there.
Can you get software for BCM and apps that can clear faults & codes - in ecm not service or engine light😏
any links would be plenty appreciated, I can share what I’ve researched and F/C/R
thanx

Real scan tool, it’s just software that was made exclusive it was a strategy to bring customers to dealerships.
And a new breed of tech’s that without a device giving off correct fault codes they were lost,
I can go into HSV and there will be a few who really know there stuff then the rest service, supply/fit look at faults take that to sales and they sell the customer.
So I’ve had mine tuned because HSV can’t for legalities and depending on BCM module you will do much the same as reformatting a hard drive.
But my limited understanding first time with ECM & BCM but BODY CONTROL also controls unique settings to operate access vehicle
