Is your Chevy Astro, GMC Safari, or GM truck experiencing bizarre electrical problems?
If you’re dealing with flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own, you’re likely facing a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and unpredictable issues. Don’t let these electrical gremlins sideline your vehicle. This is the reliable, straightforward solution you need.
Common Symptoms of a Failing GM BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on or not turning on).
- ✔ The anti-theft or security light stays illuminated, preventing the vehicle from starting.
- ✔ Remote Keyless Entry (RKE) fob stops working.
- ✔ Instrument cluster gauges behaving erratically or displaying false warnings.
- ✔ Diagnostic trouble codes (DTCs) like U1000, B1000, or other communication errors.

Installation and Setup
Installation is straightforward, but some post-installation steps may be required depending on your specific vehicle’s configuration.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Please note: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to have this BCM programmed?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN at checkout, and the module will arrive ready to be installed.
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, interior/exterior lights, security system, and wipers.
How do I find my original BCM part number?
Your original BCM is typically located in the center dash area or under the steering column. The part number is printed on a sticker on the module’s housing.
Will this fix my ‘Security’ light issue?
Yes, a faulty BCM is a very common cause of security system problems, including a persistent security light and no-start conditions. This programmed module is designed to resolve those issues.
What if my airbag light comes on after I install it?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Is there a core charge?
No, there is no core charge for this part. You can keep your original module.
