What is the Bcm in a Chevy Silverado

The BCM, or body control module, is a computer that controls all of the electronic accessories in your Chevy Silverado. This includes the lights, door locks, windows, and even the radio. If any of these accessories are not working properly, it is likely due to a problem with the BCM.

The BCM, or Body Control Module, is a computer in your Chevy Silverado that controls various functions of the vehicle. It can control everything from the power windows to the door locks and even the headlights. If your BCM goes bad, it can cause all sorts of problems with your truck.

Silverado Bcm Reset

If your Chevy Silverado’s BCM (body control module) has failed, you will need to reset it. This can be done by disconnecting the battery for a few minutes and then reconnecting it. You may also need to remove the fuse for the BCM.

Consult your Silverado’s owner’s manual for more information on resetting the BCM.

What Does the Bcm Control?

The BCM, or Body Control Module, is a computer that controls various body functions in a vehicle. These functions can include the headlights, taillights, interior lights, door locks, windows, mirrors, and more. The BCM is often located in the dash or center console of a vehicle.

Can You Reset Your Bcm?

On most vehicles, the Body Control Module (BCM) is responsible for controlling and integrating your cars various electronic accessories. If you have a problem with any of these accessories, you may need to reset the BCM to get it working again. Here’s how to do it:

1. Disconnect the battery. This will prevent any electrical shorts from damaging the BCM while you’re working on it. 2. Remove the BCM from its location in the vehicle.

Consult your service manual for specific instructions on how to do this, as it will vary depending on make and model. 3. Inspect the BCM for any physical damage, such as cracks or loose connections. If there is physical damage, it will need to be repaired or replaced before proceeding.

4. Use a voltmeter to test the voltage output of each pin on the BCM connector. Compare your readings to those listed in your service manual to ensure they are within specification. If not, check all wiring and connections leading to and from the BCM for issues until you find the cause of the problem.

5 . Once everything checks out electrically, reinstall the BCM and reconnect the battery.

Does Bcm Need to Be Reprogrammed?

It’s a common question: does BCM need to be reprogrammed? The answer is not as simple as a yes or no. In some cases, the BCM will need to be reprogrammed in order for it to work properly.

Other times, the BCM may not need to be reprogrammed at all. It really depends on the situation. If you’re having issues with your BCM, the first thing you should do is take it to a qualified technician who can diagnose the problem and recommend the best course of action.

In some cases, reprogramming the BCM may be the solution. But in other cases, it may not be necessary. So it’s important to get a professional opinion before taking any further steps.

How Do You Test Your Body Control Module?

There are a few different ways that you can test your body control module (BCM). One way is to use a BCM tester, which can be found at most auto parts stores. This will allow you to test the functionality of the BCM and its various components.

Another way to test the BCM is by using a multimeter. You’ll want to set the multimeter to the “ohm” setting and then touch the probes to the two terminals on the BCM connector. If the multimeter reads infinity, then there is an open circuit and the BCM is not functioning properly.

If it reads zero, then there is a short circuit and again, the BCM is not working correctly. Finally, you can also test the BCM by observing its output signals. Most BCMs have LED indicators that will light up when certain functions are activated.

For example, if you turn on the headlights, you should see an LED light up on the BCM indicating that it has received power from the headlight switch. If you don’t see this indicator light, then there may be an issue with either the headlight switch or the BCM itself.


The BCM in a Chevy Silverado is the Body Control Module. It is responsible for managing various electronic functions in the vehicle, such as the door locks, interior lights, and security system. It can also store data about the vehicle’s maintenance schedule and service history.
