Q: Can you use a used bcm with out having it reprogrammed

asked by on

I'm trying to find out if you can replace a bcm with a used one with out having it reprogrammed.

My car has 185000 miles.
My car has an automatic transmission.

Hi Andrew. Unfortunately, any control module needs to be flashed or reprogrammed to link to the sensors and monitors of an individual vehicle in order for them to work correctly. This needs to be completed by a dealer or some automotive specialists, as they control security codes to reprogram these systems.
