Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical gremlins in your car, truck, or SUV? Flickering lights, malfunctioning power windows, a haywire security system, or strange instrument cluster behavior are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of unpredictable and annoying problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and security.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Warning lights (like Airbag or ABS) appearing on the dash for no reason.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Problems with the keyless entry system or remote start.
- ✔ Rapid battery drain while the vehicle is parked.
The Direct Solution: A VIN-Programmed Module
Don’t let a faulty BCM keep you off the road. This Programmed GM Body Control Module is the reliable, straightforward solution to restore your vehicle’s proper operation. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before we ship it. This ensures it communicates correctly with your vehicle’s other computers, saving you a costly trip to the dealership for programming. With the latest GM software updates installed, you’re getting a part that’s ready for installation right out of the box.
This module is a direct replacement for a wide range of original part numbers, including 15872421, 22860591, 25892622, and many more. Please verify your part number or check the fitment list to ensure compatibility.
Installation and Post-Install Steps
Installation is generally straightforward, but it’s crucial to disconnect the battery before beginning. Once the new BCM is installed, most functions will work immediately. However, depending on your specific model, a couple of simple relearn procedures may be necessary:
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light and traction control operation.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s non-engine related functions. It controls features like power windows, locks, lights, the security system, wipers, and the instrument panel.
How do I provide my VIN for programming?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN, or add it to the notes section during checkout. We cannot ship your part until we receive the VIN.
Is this part difficult to install?
For someone with moderate mechanical skill, the physical replacement is typically not difficult. The BCM is usually located under the dash. The most important part is that our pre-programming service eliminates the need for dealer-level computer work, making the process much simpler.
Do I need to send my old part back?
No. This part is sold without a core charge, so you can keep your original module.
What if my airbag light is on after I install this BCM?
This can happen. It means the new BCM needs to be synced with the airbag system’s computer (SDM). A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix all of my car’s electrical problems?
This module will correct all issues directly caused by a faulty BCM. However, it’s essential to ensure the BCM is the root cause of your problems. Issues like a bad ground, faulty wiring, or a failing sensor can sometimes mimic BCM failure.
