Restore Full Functionality to Your Vehicle’s Electronics
Are you battling bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or strange warning messages on your dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central computer for your car’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable problems. This replacement Body Control Module, part number 15299986, is the definitive solution to get your vehicle operating correctly again.
From the Diagnostic Bay
We had a 2012 Caprice PPV (Police Pursuit Vehicle) come into the shop with a list of complaints that seemed unrelated. The dome lights would stay on, the driver’s power window worked intermittently, and the radio would randomly shut off. The officer driving it was convinced the car was haunted. After checking grounds and wiring harnesses, we connected our diagnostic tool and found multiple communication errors pointing to the BCM. A failing BCM can disrupt the entire vehicle network, causing chaos. Once we installed a VIN-programmed replacement, all the gremlins vanished, and the vehicle was back in service the same day.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, door locks, or mirrors behaving unpredictably.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Vehicle security system faults or false alarms.
- ✔ Inoperative remote keyless entry (key fob).
- ✔ Dashboard warning lights for various systems (ABS, Airbag, Traction Control) illuminating.
- ✔ Wipers turning on by themselves or not working when commanded.

Post-Installation Requirements:
While our programming handles the majority of the setup, some vehicles may require one or two simple relearn procedures after installation. These can often be performed with a high-end scan tool. This may include an Airbag System Sync (‘Setup SDM Primary Key in BCM’) if the airbag light is on, or a Brake Pedal Position Relearn for proper brake light and stability control function. Always consult a factory service manual for your specific model.
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 electronic accessories like power windows, lights, door locks, the security system, and wipers. It acts as a central hub for these functions.
Is this part difficult to install?
The physical installation is typically straightforward, involving the removal of a few dash panels and unplugging the old module to plug in the new one. The location varies by model (e.g., under the dash, behind the glove box). The key benefit of our service is that the complex software programming is already done for you.
What do I need to do after I purchase?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot ship your part until we have this information, as we use it to program the module specifically for your car.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after installation?
If the airbag warning light appears, a procedure called ‘Setup SDM Primary Key in BCM’ needs to be performed with a professional diagnostic tool. This syncs the new BCM with your vehicle’s existing airbag system.
