Is your 2002 Cadillac Escalade, Tahoe, Yukon, or other GM truck experiencing bizarre electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or random warning messages on your dash are often symptoms of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable issues. This replacement BCM, part number 15063577, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
We take the guesswork and hassle out of the repair process. Unlike a generic part from a local store, this BCM is professionally programmed with the latest GM software updates specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and we’ll flash the module before it ships. This means no expensive trip to the dealership for programming, saving you time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ The security system engaging randomly or the vehicle not starting due to a security fault.
- ✔ Horn or windshield wipers activating without input.
- ✔ Inaccurate readings on the instrument cluster or warning lights that won’t turn off.
- ✔ Complete loss of communication with other vehicle modules, leading to multiple system failures.

From the Diagnostic Bay
We had a 2002 Yukon XL come in with a classic ‘haunted truck’ complaint. The owner said the horn would blare randomly in his driveway, the interior lights would flicker while driving, and the power locks had a mind of their own. Our initial scan showed multiple communication codes. After checking the wiring for obvious damage, we focused on the BCM, located under the driver’s side dash. We found evidence of water intrusion from a leaky windshield seal that had corroded the BCM’s circuit board. Installing a VIN-programmed BCM like this one solved every single issue instantly. It’s a common failure point on these vehicles, and a pre-programmed module is the most efficient fix.
Installation and Post-Install Procedures
The BCM is typically located under the steering column. While installation is straightforward for a DIYer with mechanical experience, some post-installation steps may be necessary depending on your vehicle’s specific configuration.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade diagnostic tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be required to ensure correct brake light operation and traction control function.
Disclaimer: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.
There is no core charge for this part. You can keep your original module.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Is this BCM truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible. However, as noted, some vehicles may require additional relearn procedures for the airbag or brake systems, which need a professional scan tool.
Do I have to provide my VIN?
Yes. Providing your VIN is mandatory. We cannot ship your order until we receive your VIN, as we need it to program the module correctly for your specific vehicle options.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A qualified technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Where is the BCM located on my 2002 Escalade?
The BCM is located under the driver’s side of the dashboard, typically attached to a bracket near the steering column.
Will this fix my specific electrical problem?
This part is a direct solution for a faulty BCM. If your vehicle’s symptoms match those of a failed BCM and you have ruled out other causes like bad wiring or fuses, this module is the correct repair.
