Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM

Installation and Post-Install Notes
Installation is typically straightforward, involving locating the old module (often under the steering column or in the center dash), disconnecting the battery, swapping the modules, and reconnecting the battery. However, in some cases, additional steps may be required:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the modules.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed on some models to ensure correct brake light and traction control operation.
There is no core charge for this part. You can keep your original module.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and more.
Is this BCM ready to install when I receive it?
Yes! This is a key benefit of our service. We program the module to the VIN you provide during checkout. This makes the installation process as simple as possible, with no dealer programming required.
How do I find my vehicle’s original BCM part number?
The part number is printed on a sticker on the case of your original BCM. You will typically need to remove the module from its mounting location (usually under the dash) to see the sticker clearly.
What if my airbag light comes on after I install this?
This can happen on some models. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by a repair shop with a high-level diagnostic tool.
Do I need to send my old part back?
No. We do not require you to return your original module. There is no core charge associated with this purchase.
This part 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 (15063578, 15081796, etc.). Providing your VIN for programming ensures it will function correctly for your specific model and options.
