Alternator output? - Toyota Yaris Forums

It's strange with batteries in newer cars. There can be enough power to start the engine but as it cranks can drop low enough to mess up other electronics.

I know on my '05, when the key is turned to the ON pos, and the doors are closed, the door lock. When the car is turned off, the doors unlock. When my battery started getting really low a few years ago in the crazy cold weather we had, my door would lock, but not unlock when turned off.

I've also heard of other with stage behaviour all caused by low batteries.

And you should be testing the charging system at 2000rpm as least. Idle voltage can vary too much depending on battery status and load.
