Have you ever had to reset a body control module (BCM) on your car? If so, you’re not alone. BCMs are one of those things that most people don’t think about until they have to do it. And when you have to do it, it can be a pain in the neck. In this post, we’re going to teach you how to reset a BCM in under five minutes flat. So whether you’re having car troubles or just want to fix something yourself, read on and get started!

What is a Body Control Module (BCM)?

A Body Control Module (BCM) is a control unit that resides in the instrument panel of many modern cars. It contains the electrical and mechanical components necessary to send commands to the various systems in a car, including the airbag system.

If you are having trouble with your car’s airbag system, it may be helpful to reset your BCM. To do this, you will need to remove the cover on the instrument panel, located near the steering wheel. Underneath this cover is a small circuit board with several connectors on it. You will need to remove these connectors and reattach them in a different order than they were originally attached. After completing this step, your car should be able to use its airbag system again.

How do I reset my BCM?

If your BCM is not working correctly, you can reset it by following these steps:
1) Disconnect the battery cables.
2) Remove the screws that hold the cover in place.
3) Lift off the cover.
4) Find and remove the chip (or chips).
5) Replace the chip (or chips).

What are the symptoms of a BCM problem?

There are a few different symptoms that may indicate that your BCM is not functioning correctly. These include:

– difficulty turning the car over or starting it

– poor fuel economy

– reduced performance in a certain area of your vehicle, such as the acceleration or braking
