Post-Installation Procedures
While this module is designed for a simple installation, some vehicles may require additional steps to sync all systems perfectly. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and more. It’s essential for modern vehicle comfort and convenience features.
Do I need to get this programmed at a dealership?
No. We pre-program the module to your vehicle’s VIN before shipping it. This saves you a trip to the dealer and the extra cost of programming services.
Where do I provide my VIN?
You can provide your vehicle’s 17-digit VIN during the checkout process or by sending us a message after your purchase. We cannot ship the module until we have your VIN.
Is this a difficult part to replace?
The BCM is typically located under the dashboard on the driver’s or passenger’s side. Replacement usually involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. It is a manageable job for a DIYer with basic tools, but we always recommend consulting a service manual.
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 I install it?
This can happen on some vehicles. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called “Setup SDM Primary Key in BCM” must be performed with a professional-grade scan tool to resolve this.
