Restore Your Vehicle’s Electronic Systems with a VIN-Programmed BCM
Are you battling frustrating and unpredictable electrical issues in your 2010 Chevy Suburban 1500? From power windows that have a mind of their own to dashboard warning lights that flicker without reason, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing problems. This replacement Body Control Module, part number 20815898, is the definitive solution to restore your vehicle’s functionality and peace of mind.
Unlike a standard part from a local store, this BCM is not a one-size-fits-all solution. We professionally program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures complete compatibility with your Suburban’s existing systems and options, eliminating the need for an expensive and time-consuming visit to the dealership for programming. Simply install the module, perform any necessary relearn procedures, and get back on the road.
From the Diagnostic Bay
We once had a 2010 Yukon XL (which uses a similar platform to the Suburban) come into the shop with a complaint of the radio turning on and off by itself and the door locks cycling randomly while driving. The owner had already replaced the battery and checked the alternator, but the electrical gremlins persisted. A quick scan of the vehicle’s network pointed to communication errors originating from the BCM. Once we installed a VIN-programmed BCM, every single one of the strange electrical issues vanished. It’s a reminder that what seems like multiple unrelated problems can often be traced back to this single, vital component.
Common Symptoms of a Failing 2010 Suburban BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ Malfunctioning keyless entry and remote start systems.
- ✔ False warnings on the instrument cluster, such as ‘Service StabiliTrak’ or ‘Service Airbag’.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire due to security system faults.
- ✔ Climate control system behaving unpredictably.
Installation and Required Procedures
Physical installation of the BCM is typically straightforward, often located under the steering column on the driver’s side. However, after the new module is connected, your vehicle may require specific electronic relearn procedures to fully integrate the new component. Please be aware of the following potential steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure proper operation of the brake lights and traction control systems, a brake pedal position sensor recalibration might be required.
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 do on my Suburban?
The BCM is a computer that manages and controls most of the non-engine related electronic functions in your vehicle. This includes power windows, door locks, interior and exterior lighting, security system, keyless entry, and even aspects of the climate control system.
Is this BCM ready to install out of the box?
Yes, this module comes pre-programmed to your vehicle’s VIN. This means it’s ready for physical installation. However, depending on your specific vehicle, you may need a professional scan tool to perform additional relearn procedures, such as an airbag system sync or brake pedal position relearn, after it’s installed.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship the module without it. You can typically add it as a note during checkout or send it to us in a message referencing your order number.
What if my airbag light comes on after I install the BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag computer (SDM). A technician with a capable diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this and turn off the light.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
