Installation and Post-Install Notes
Installation is typically straightforward, as the BCM is located under the steering column or in the center dash area on most compatible models. While this module is sent ready for installation, some vehicles may require additional steps after the part is in place:
- Airbag System Sync: If the airbag warning light appears after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Please note: No core charge is required. You can keep your old module.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, security system, wipers, and interior accessories.
Do I need to get this BCM programmed by a dealer?
No. This BCM comes fully programmed to your vehicle’s specific VIN before we ship it. It arrives ready for installation, saving you time and money on dealership programming fees.
Where do I provide my VIN?
You can enter your 17-digit Vehicle Identification Number (VIN) during the checkout process. Please double-check it for accuracy to ensure correct programming.
Is this part difficult to install?
For most DIY mechanics with basic tools, the installation is manageable. The BCM is typically located under the driver’s side dashboard. However, always consult a service manual for your specific vehicle. Remember that some post-installation procedures may require a professional scan tool.
What if my airbag light is on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A qualified mechanic with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
This BCM fits many vehicles. How do I know it’s right for mine?
The best way to ensure compatibility is to match the part number from your original BCM to one of the numbers listed: 15095334, 15063578, 15081796, 19208537, DKAK, or DPNU. Our VIN programming service further ensures it will function correctly for your specific model and options.
