Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, a malfunctioning security system, or power windows and locks that have a mind of their own, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This OEM-quality GM 15116066 BCM is the definitive solution, restoring full functionality and reliability to your vehicle.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ HVAC and climate control system failures or intermittent blower motor operation.
- ✔ Airbag warning light illuminated on the dash (often with DTC B1001).
- ✔ Security system malfunctions, leading to a no-start condition.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Communication errors with other vehicle modules.

This ensures that it works seamlessly with your existing components and factory settings right out of the box. The software is updated to the latest GM calibration, which can resolve issues that were present even in the original factory part. This is the most reliable way to get your 2003-2006 Yukon BCM replaced and your vehicle back on the road.
Installation and Post-Install Notes
Installation is simple for the average DIYer and typically takes less than 15 minutes. The BCM is usually located under the driver’s side dashboard, near the steering column.
- Disconnect the Battery: Always disconnect the negative battery terminal before starting work.
- Locate and Replace: Unplug the electrical connectors from the old BCM, remove it, and install the new one in its place.
- Reconnect Battery: Reconnect the battery terminal.
- Check for Airbag Light: In some cases, the airbag (SRS) light may illuminate after installation. This is because the new BCM needs to be synced with the SDM (airbag module). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed with a professional-grade scan tool.
No Core Charge: You are not required to send your old part back. This saves you time and the cost of return shipping.
Frequently Asked Questions
What exactly does this Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows and locks, security system, wipers, and HVAC blower motor, ensuring everything works as intended.
Is this part really plug-and-play?
Yes. We program the module with your vehicle’s VIN before shipping. This ensures it communicates correctly with your truck’s other systems, eliminating the need for expensive dealership programming. Just install it and you’re ready to go.
What if my airbag light comes on after I install it?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to send my old BCM back?
No. There is no core charge or requirement to return your original module. You can keep it or dispose of it at your convenience.
How do I know this fits my vehicle?
