Restore Full Functionality to Your Vehicle’s Electronics
Is your vehicle plagued by strange and frustrating electrical problems? Issues like flickering lights, malfunctioning power windows, a faulty security system, or dashboard warning lights that won’t turn off are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This replacement BCM, part number 25847588, is the definitive solution to restore your vehicle’s proper operation and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system faults or random alarm activation.
- ✔ Dashboard warning lights (like Airbag or ABS) staying illuminated.
- ✔ Key fobs that stop working or work intermittently.
- ✔ No communication with the module when using a diagnostic scan tool.
- ✔ Unexplained battery drain when the vehicle is off.
Why Choose Our Pre-Programmed GM Body Control Module 25847588?
Getting your vehicle back to normal shouldn’t be a hassle. Unlike a standard replacement from a dealership, this BCM comes ready for installation. We take your vehicle’s VIN and program the module with the latest GM-certified software before it even leaves our facility. This critical step ensures that the BCM is perfectly matched to your vehicle’s specific options and configuration, eliminating the need for expensive post-installation programming by a dealer. This is a direct-fit, plug-and-play solution designed to get you back on the road quickly and affordably.
Installation and Required Procedures
While the module is programmed for a straightforward physical installation, some vehicle systems may require a relearn or synchronization procedure after the BCM is installed. This is a normal part of the repair process.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls a wide variety of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Is this BCM truly plug-and-play?
Yes, for most functions. We program the module to your VIN before shipping, so it will operate your vehicle’s specific options correctly upon installation. However, as noted, some systems like the airbag or brake sensor may require a simple relearn procedure with a capable scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information to ensure the module is programmed correctly for your exact vehicle.
What happens if my airbag light is on after installation?
This is a common security measure. The new BCM needs to be electronically ‘introduced’ to the airbag’s Supplemental Deployment Module (SDM). A qualified technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the system and turn off the light.
Do I need to return my old BCM?
No. This BCM is sold without a core charge. You can keep your original module.
