Restore Full Electronic Functionality to Your GM Vehicle
Are you battling bizarre electrical problems in your Saturn Outlook, GMC Acadia, or another compatible GM vehicle? Intermittent power windows, flickering dash lights, a malfunctioning security system, or even a no-start condition can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. This replacement BCM, part number 15299986, is the reliable, straightforward solution to get your vehicle back in perfect working order.
From the Diagnostic Bay
We had a 2009 GMC Acadia come into the shop with the classic “electrical gremlins.” The customer reported that sometimes the radio wouldn’t turn on, other times the power liftgate would open on its own, and the remote start was completely unreliable. After hours of checking wiring harnesses and grounds with no luck, we focused on the BCM. Swapping in a pre-programmed module like this one solved every single issue instantly. It’s a reminder that what seems like multiple unrelated problems often points to one central computer failure.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system or keyless entry system behaving unpredictably.
- ✔ Warning lights on the dashboard (like the airbag or service vehicle light) illuminating for no reason.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
Why Choose Our Pre-Programmed 2007-2010 Outlook BCM?
Forget expensive dealership visits and the hassle of finding a shop with the right tools. We simplify the repair process. When you purchase this BCM, we will program it specifically for your vehicle using the VIN you provide. This means it arrives at your door loaded with the latest GM software updates and is ready for installation.

Installation and Post-Install Notes
While installation is straightforward for many, please be aware of potential post-installation procedures. Depending on your vehicle’s specific configuration, additional steps may be required:
- Airbag System Sync: If your 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 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 function.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic accessories, such as power windows, locks, lights, security system, and interior climate controls.
Is this BCM ready to install when I receive it?
Yes! This BCM is sold as a plug-and-play solution. We program it with the latest GM software using the VIN you provide, so it’s ready for installation right out of the box.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have programmed it.
What if my airbag light comes on after I install the BCM?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
