Hey everyone,

I have been having issues with my power door locks on my 2012 Mazda 3 Gs-Sky Manual Sport. After using an OBD2 scanner to diagnose the problem, it showed there is "An abnormal message from BCM (Failure type 64) error code U0428.

The power door lock on the side door panel and via the key fob/remote are both not working. I have to go to each door and manually lock them. Once I have locked all the doors by hand, however - if I then press the lock button on my Key Remote, the car will beep and flash the lights like it should, indicating the doors are all locked.

I am guessing I will have to replace my BCM so I am wondering if any of the users here have any resources that can help with this. I read a couple of archived posts but they all ended with "I will go to the dealership to find out" and then never followed up.

Any help is greatly appreciated!

- Ryan
