Post-Installation Information
While this BCM is designed for a straightforward installation, some vehicles may require additional relearn procedures. These are simple steps that can often be performed with a capable diagnostic scan tool:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and instrument panel gauges. It acts as a central hub for these electronic features.
Do I need to program this BCM?
No. This BCM comes fully programmed to your vehicle’s VIN before it is shipped. Just provide us with your VIN during or after checkout, and it will arrive ready to install.
Is this part truly plug-and-play?
For most vehicles, yes. Once installed, it will function immediately. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor if related warning lights appear.
What if my airbag light turns on after I install the new BCM?
This indicates the new BCM needs to be synced with your vehicle’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
How do I find my original BCM part number?
Your original BCM is typically located under the steering column or behind the center dash. The part number is printed on a sticker on the module’s housing. Matching it to one of the compatible numbers (like DKAK, 15063578, etc.) ensures a perfect fit.
Do I need to send my old part back?
No, there is no core charge for this module. You can keep your original part.
