Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you battling frustrating electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or even a vehicle that refuses to start can all point to 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 wide range of confusing and unpredictable problems. This isn’t just an inconvenience; it can compromise your vehicle’s safety and reliability, whether it’s a hardworking Savana van or a family-hauling Acadia.
Common Symptoms & Your Solution
Don’t let a faulty BCM keep you off the road. If you’re experiencing any of the following issues, this pre-programmed module is your definitive solution:
- Intermittent or non-working interior/exterior lights
- Power windows, door locks, or mirrors operating erratically
- The security system engaging randomly or preventing the engine from starting
- Warning lights on the dash (like the airbag light) with no other apparent cause
- Communication errors with other vehicle modules (DTC U-codes)

From the Technician’s Bench: A customer brought in their 2010 Express van with a classic “haunted vehicle” complaint. The dome lights would flicker, the radio would cut out, and occasionally it wouldn’t start. They had already replaced the battery and alternator with no luck. After a quick diagnostic scan, we found multiple communication codes pointing to the BCM. Instead of a costly and time-consuming dealer visit, we installed a pre-programmed module. The entire job took less than an hour, and the van was back in service for their business the same day. This is the power of a ready-to-install solution—it saves diagnostic headaches and gets you, or your customer, back on the road fast.
By choosing this Programmed GM Body Control Module 15948438, you’re not just buying a part; you’re buying a complete, hassle-free solution designed to get your vehicle working correctly again.
Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your Vehicle Identification Number (VIN) allows us to access the specific software and calibration files for your exact model, year, and options. Programming the BCM with this data ensures it communicates perfectly with your vehicle’s other computers, making the installation process plug-and-play.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is typically straightforward. The BCM is often located under the dash on the driver’s or passenger’s side. The main challenge is usually programming, which we have already completed for you. However, we always recommend consulting a service manual for your specific vehicle’s procedure.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag warning light is on after you install the module, a “Setup SDM Primary Key in BCM” procedure will need to be performed with a professional-grade scan tool to turn off the light.
Are any other procedures required after installation?
Depending on your vehicle, a Brake Pedal Position Sensor relearn procedure may be necessary to ensure proper brake light and traction control operation. These are simple procedures that can be performed with a compatible diagnostic tool. Please refer to your factory service manual for specific requirements.
Do I have to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, saving you the hassle and expense of a return shipment.
What makes this a better option than going to a dealer?
Our Programmed GM Body Control Module 15948438 offers a more convenient and cost-effective solution. You get a fully updated and programmed part delivered to your door, eliminating the need to have your vehicle towed to a dealership and paying their higher labor and programming fees.
