Post-Installation Information
After installing your new BCM, some vehicles may require a simple relearn procedure to sync with other systems. This is a normal part of the process. For instance, if the airbag light is on, a technician may need to perform a ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control function. These procedures are straightforward for any qualified technician with a professional scan tool.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security systems, and more. It acts as a central hub for these functions.
Do I need to get this part programmed?
No. We handle the programming for you before we ship the part. Just provide us with your vehicle’s 17-digit VIN at checkout, and the module will arrive ready to be installed.
Is this part difficult to install?
Installation is typically straightforward for someone with moderate DIY mechanical skill. The BCM is usually located under the dashboard on the driver’s or passenger’s side. The main task is disconnecting the battery and then carefully swapping the electrical connectors from the old module to the new one.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after installation?
This can happen on some models. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A technician with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my specific electrical problem?
If your vehicle is exhibiting multiple symptoms listed above, a failing BCM is a very likely cause. This part is designed to correct those issues. However, always ensure a proper diagnosis has been performed to confirm the BCM is the point of failure.
