Restore Full Functionality to Your Vehicle’s Electronics
Is your 2010 GMC Yukon or other GM vehicle suffering from strange and unpredictable electrical problems? A failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your power windows and locks to your interior lighting and security system. When it fails, it can cause a cascade of frustrating issues that can be difficult to diagnose. This replacement Body Control Module, part number 20921436, is the reliable solution to get your vehicle back in perfect working order.
We make the replacement process simple. Unlike a trip to the dealership, this BCM comes pre-programmed to your vehicle’s specific VIN. Simply provide us with your VIN during checkout, and our technicians will flash the module with the latest GM factory software updates for your exact configuration. This ensures a seamless integration and restores original performance without the need for expensive dealer programming tools.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system acting up, or the vehicle not starting due to a security lockout.
- ✔ The radio or infotainment system randomly turning on or off.
- ✔ False warning lights appearing on the instrument cluster (e.g., ‘Service StabiliTrak’, ‘Service Airbag’).
- ✔ Rapid battery drain when the vehicle is turned off.
Solving Issues with a Programmed 2010 Yukon Body Control Module
This isn’t just a replacement part; it’s a complete solution. By installing our VIN-programmed 2010 Yukon Body Control Module, you are bypassing the most complicated part of the repair. The module arrives at your door ready for physical installation. While the process is largely plug-and-play, some vehicles may require simple, post-installation relearn procedures to sync components like the airbag system or brake pedal position sensor. These are straightforward tasks for any competent mechanic or advanced DIYer with a capable scan tool.
Post-Installation Requirements
Please be aware of the following potential procedures after installing the new BCM:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional diagnostic tool. This syncs 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 operation and to clear any related trouble codes.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s 17-digit VIN at checkout, and it will arrive ready for installation.
Is this a plug-and-play installation?
For most vehicles, it is a direct physical replacement. However, as noted, some models may require additional relearn procedures for systems like the airbags or brakes, which can be done with a professional-grade scan tool.
What happens if my airbag light turns on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag’s Sensing and Diagnostic Module (SDM). A mechanic with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How do I find my vehicle’s VIN?
Your VIN can be found on your vehicle’s registration, insurance card, or on a placard on the driver’s side of the dashboard visible through the windshield.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
