Restore Full Functionality to Your Vehicle’s Electronics
Are you battling bizarre electrical issues in your 2010 Cadillac Escalade EXT? Flickering lights, malfunctioning power windows or locks, a security system that acts on its own, or warning lights that won’t go away are common signs of 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 cascade of frustrating and difficult-to-diagnose problems. This replacement Body Control Module, part number 15828601, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
From the Diagnostic Bay
We once had a 2010 Tahoe in the shop with the owner at his wit’s end. The radio would randomly turn off, the dome lights would stay on, and the key fob worked intermittently. He had already replaced the battery and checked all the fuses. A deep dive with our diagnostic scanner showed multiple communication loss codes with various modules, all pointing back to one culprit: the BCM. Once we installed a VIN-programmed BCM like this one, all the electrical gremlins vanished instantly. It’s often the central component that mechanics overlook, leading to wasted time and money on other parts.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lighting.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Intermittent or complete failure of the radio and infotainment system.
- ✔ False alarms or issues with the factory security system.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Various warning lights on the dashboard, including airbag or service messages.
- ✔ Inability for a diagnostic scan tool to communicate with the vehicle.

Important Post-Installation Information
While our programming handles the majority of the setup, some vehicle systems may require a simple ‘relearn’ procedure after installation to sync with the new BCM.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool and syncs the new BCM with your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready for installation with the latest GM software.
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer that acts as the brain for your vehicle’s electronic accessories. It manages functions like power windows, locks, lights, wipers, the security system, and the instrument cluster.
Is this a simple plug-and-play installation?
For the most part, yes. The physical installation involves disconnecting the battery and swapping the old module with this new one. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake sensor.
How do I find the part number on my original BCM?
The BCM is typically located under the driver’s side dashboard, near the steering column. The part number will be on a white sticker on the module’s housing.
What if my airbag light comes on after I install it?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A technician with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back.
