Restore Full Functionality to Your Vehicle’s Electronics
Are you experiencing a cascade of bizarre electrical issues in your GM vehicle? From flickering lights and malfunctioning power windows to a car that won’t start, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause frustrating and unpredictable problems. This replacement GM Body Control Module is the reliable, cost-effective solution to get your vehicle back in perfect working order.
Is Your GM Body Control Module Failing?
A faulty BCM can manifest in numerous ways, often seeming unrelated. If you’re noticing several of the following symptoms, it’s a strong indicator that your BCM needs replacement.
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning radio or instrument cluster gauges.
- ✔ Security system faults or a vehicle that won’t start, even with a good battery.
- ✔ False warning lights on the dashboard, such as the airbag or check engine light.
- ✔ Key fob not working correctly.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with other modules (U-codes).

- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and instrument panel functions.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. However, its location varies by model (e.g., under the dash, behind the glove box). The key benefit of our service is that the module arrives pre-programmed, eliminating the most complex step.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
What if my original part number is not 15828601?
This module is a compatible replacement for a long list of GM part numbers. Please check the extensive list provided in our fitment data to confirm that your original part number is included.
Is there a core charge for my old BCM?
No, there is no core charge. You can keep your original module.
Will this fix my ‘Service Airbag’ light?
If the BCM is the cause of the light, yes. However, after installation, you may need a technician with a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and clear the light.
