Can electrical use data be pulled from ECU?

2021 ORP gave me a slow start today after sitting a couple days. It’s garaged, with garage temps mid-40s to low 50s, so not terribly cold.

The battery is only 16 months old. The original battery failed at 34 months. None of this is particularly alarming, but I was curious if the vehicle stores any data pertaining to current draw while ignition is off that can be pulled with a decent aftermarket scanner like an Xtool D8 or similar

 

You will have to go looking for that parasitic draw manually with a voltmeter.

 

That’s kinda difficult when the ECU controls a lot of offline functions. Ain’t like it used to be.

I suspect it’s the Garmin dash cam power adapter that plugs into the OBD
