Restore Full Electronic Functionality to Your GM Vehicle
Are you battling bizarre electrical gremlins in your Cadillac SRX, Chevy Impala, or GMC Acadia? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are 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 falters, it can cause a wide range of frustrating and difficult-to-diagnose problems. This replacement Body Control Module, part number 15299986, is the definitive solution to restore order and reliability to your vehicle’s systems.
From the Diagnostic Bay
We had a 2008 Cadillac SRX come in with a complaint that was driving the owner crazy: the windshield wipers would turn on randomly, even with the switch off. On top of that, the driver’s side power window would only work intermittently. We checked the switches and wiring, which all tested fine. After connecting our diagnostic tool, we saw multiple communication error codes pointing to the BCM. Instead of a costly and time-consuming trip to the dealer, we installed one of our VIN-programmed modules. The entire job took less than an hour, and all the strange electrical issues were gone. It’s a common failure, and having a pre-programmed module is the fastest way back on the road.
Is Your BCM Failing? Common Symptoms:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system engaging randomly or preventing the car from starting.
- ✔ Dashboard warning lights (like the airbag or brake light) illuminating for no reason.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Key fob not being recognized by the vehicle.
The Simple, Dealer-Free Solution
Replacing a BCM traditionally required a trip to the dealership for expensive programming. Our process eliminates that hassle. When you purchase this module, simply provide us with your vehicle’s 17-digit VIN. Our technicians will flash the unit with the latest, most stable software directly from GM, ensuring it is perfectly matched to your vehicle’s specific options and configuration. This makes the installation process as close to plug-and-play as possible, getting your 2007-2009 SRX BCM and other compatible models back to factory-fresh operation without the dealer visit.
Post-Installation Requirements
While this module is pre-programmed, some vehicles require simple relearn procedures after installation to sync all systems. These can often be performed with a high-end diagnostic tool. Key procedures may include:
- Airbag System Sync: If the airbag warning light is on 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: To ensure correct brake light and traction control function, a brake pedal position sensor recalibration might be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

On the 2007-2009 Cadillac SRX, the BCM is typically located behind the left-hand (driver’s side) of the dashboard.
