Good morning,

The issue is low voltage.

I would start by replacing the battery. 12 volts is a dead battery. it needs 12.6 volts for systems to work.

Never, never pull off a battery cable while running. first, it does nothing as far as testing. it damages module from voltage surge. you will cause more damage.

You check the charging system with the engine running. it should be 14 to 14.5 volts.

Had the same issue with my Honda Civic , took it to the shop and they said the wiring to the alternator was bad so they replaced the wire. Have not had a problem since!
