Installation and Post-Install Notes:
While installation is straightforward, some vehicles may require simple post-install procedures. If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems. Additionally, a Brake Pedal Position Relearn may be necessary on some models to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and instrument cluster gauges.
Do I need to get this BCM programmed?
No! We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install with the latest GM software.
Is this part difficult to install?
For most DIY mechanics, the installation is straightforward. The BCM is typically located under the steering column or in the center dash area. It involves disconnecting the battery, removing a few trim panels, and swapping the module. However, please see our post-installation notes, as some relearn procedures may be required.
What information do you need from me?
We require your 17-digit Vehicle Identification Number (VIN) to program the BCM specifically for your vehicle’s factory options. Please provide it during or after your purchase.
What if my airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my check engine light?
Generally, no. The BCM controls body electronics, while the Engine Control Module (ECM) or Powertrain Control Module (PCM) manages engine and transmission functions that trigger the check engine light.
