Installation and Post-Install Notes
Installation is straightforward for anyone with basic mechanical skills. The BCM is typically located under the steering column or in the center dash area. After installation, please be aware of the following potential procedures:
- Airbag System Sync: 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. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
There is no core charge for this module. You can keep your original part.
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 functions, such as power windows, power locks, interior and exterior lighting, the security system, and the horn.
Is this BCM difficult to install?
For most DIY mechanics, the installation is straightforward. It typically involves removing a few dash panels to access the module, unplugging the old one, and plugging in the new one. Location varies between trucks (under steering column) and vans (center dash).
Do I need to get this module programmed by a dealer?
No. The main benefit of our service is that we program the BCM to your vehicle’s VIN before we ship it to you. This makes the installation process plug-and-play, saving you time and money.
How do I provide my Vehicle Identification Number (VIN)?
You can enter your VIN during the checkout process or send it to us via email after you place your order, referencing your order number. We cannot ship the part until we have your VIN.
What if the airbag light comes on after I install the new BCM?
This is not a defect. 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.
Will this fix my specific problem?
This module will correct any issues directly caused by a faulty BCM. If you’re experiencing the symptoms listed, there is a very high probability that a failing BCM is the cause. Proper vehicle diagnosis is always recommended.
