Volvo guys I could use some help. (Door locks)
2012 Volvo VNL, driver’s side door lock, locks with the remote but then immediately unlocks by itself, passenger side is working fine. I jumped to the wrong conclusion, and replaced the actuator. It fixed nothing. Multimeter testing shows no shorts. I removed and cleaned the actual mechanism and it seems to be operating as intended. I then jumped to another wrong conclusion and replaced the central control module. It fixed nothing. It locks fine with key or manually inside.....I am stumped!
Also, airbag module has no codes so I don’t think it is triggering the unlock pulse.

Thanks in advance for any ideas!

I think the only reason it would do that is if maybe the door senses that it isnt closed properly. The 2016 volvo i used to drive, did that randomly. I't was weird.... i'd look really paranoid at the truck stops checking 2 or 3 times if it did lock properly. I stopped using the remote and locked the truck up manually.

Must be nice to drive a Volvo with remote controlled door locks, I drive a 2006 Volvo and no remote control remote but they do have door lock relay so it might be something to look at.
