Restore Full Control and Eliminate Electrical Headaches in Your GM SUV
Are you battling frustrating electrical gremlins in your 2002 Cadillac Escalade or other GM SUV? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or an intermittent no-start condition are all classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant annoyance. It’s the central command center for your vehicle’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it can be a safety issue when exterior lights or door locks don’t operate as expected.

Before this part ever ships, we flash it with the latest official GM software, specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN). This means it arrives at your door ready for installation, saving you from costly programming fees and the need for specialized, high-end scan tools. It’s a direct-fit replacement for service numbers 15063577, 15081857, 19208544, 15095335, DKAJ, and DPNW, ensuring perfect integration with your vehicle’s systems.
Is Your GM Truck Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.

From the Diagnostic Bay: A Real-World Repair
“A customer brought in his 2002 Yukon XL last month with a truly baffling set of problems. The dome lights would flicker while driving, the driver’s side power lock wouldn’t work with the fob, and twice it had refused to start, only to fire right up an hour later. He had already replaced the battery and checked the alternator. After connecting my diagnostic tool, I saw several communication loss codes pointing toward the BCM. Instead of a complex rewiring job, we installed one of these VIN-programmed modules. The entire job took less than an hour, and every single electrical issue was resolved. It’s a prime example of how this single component can fix a wide range of seemingly unrelated problems, and having it pre-programmed saved the customer hundreds compared to a dealership visit.”
Your Straightforward Installation Guide
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On these GM models, the BCM is typically found under the driver’s side of the dashboard, near the steering column.
- Remove Trim Panels: You may need to remove the lower dash knee bolster or trim panels to gain clear access to the module.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- Post-Installation Procedures (CRITICAL): Reconnect the battery. You must now perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible diagnostic tool to clear the airbag light. Some vehicles may also require a brake pedal position sensor recalibration for proper ABS and traction control function.
- Test All Functions: Start the vehicle and thoroughly test all body electronics: lights, locks, windows, radio, and wipers to confirm a successful repair.

Frequently Asked Questions
Do I need to program this module after I receive it?
No. We program the module to your specific VIN before shipping, so it arrives ready to install. This saves you a trip to the dealership.
What is a Body Control Module (BCM)?
The 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, lights, security systems, and door locks.
Where is the BCM located on my 2002 Escalade?
The BCM is located under the driver’s side dashboard, attached near the steering column.
What happens if I don’t reset the airbag light or recalibrate the brake pedal?
The airbag warning light will remain on, indicating a fault in the safety system. Failing to recalibrate the brake pedal (if required for your vehicle) could lead to improper brake light operation or issues with the anti-lock braking system.
Is this part difficult to install for a DIYer?
For someone with basic mechanical skills, the physical replacement is straightforward. The most critical part is having access to a diagnostic tool capable of performing the post-installation procedures like the SDM key setup.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot program or ship the module without it.
