Is Your GM Truck or SUV Experiencing Strange Electrical Problems?
The Body Control Module, or BCM, is the central nervous system for your vehicle’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and wipers. When the BCM starts to fail in vehicles like the 2002 Cadillac Escalade, Silverado, or Sierra, it can lead to a host of confusing and frustrating issues that seem to have no single cause. This isn’t just an inconvenience; a faulty BCM can compromise your vehicle’s security and functionality.
Common Symptoms of a Failing 2002 Escalade BCM
If you’re noticing any of the following issues, your Body Control Module is the likely culprit. A failing BCM often creates problems that appear unrelated, making diagnosis difficult for the average owner. Replacing it with a correctly programmed unit is the definitive solution.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior and/or exterior lights flickering, staying on, or not turning on.
- ✔ The vehicle’s anti-theft or security system acting up, causing no-start conditions.
- ✔ Remote keyless entry (key fob) not working or responding inconsistently.
- ✔ Windshield wipers behaving strangely (e.g., won’t turn off).
- ✔ The instrument panel displaying incorrect information or warning lights.
- ✔ Diagnostic trouble codes (DTCs) indicating a loss of communication with the BCM.
A True Plug-and-Play Solution
Don’t waste time and money at the dealership. We make this repair simple. This Body Control Module is a direct-fit replacement for part number 15081796 and other interchangeable numbers. The critical difference is our service: we program the module to your vehicle’s specific VIN before it ships. This means it arrives ready for installation, loaded with the latest software updates from GM. There is no need for expensive dealer-only scan tools or additional programming fees.
Important Post-Installation Information
While our programming handles the majority of the setup, some GM vehicles may require a simple relearn procedure after installation. These can typically be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
This module is a direct replacement for part numbers: 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU.

Frequently Asked Questions
Do I need to have this BCM programmed?
No. We handle all the programming for you. Simply provide us with your vehicle’s VIN during or after checkout, and we will flash the module with the correct software before shipping it to you.
What is a BCM and what does it do?
The BCM, or Body Control Module, is a computer that manages your vehicle’s non-engine related electronic systems, such as lights, windows, locks, wipers, and the security system.
Is this a simple plug-and-play installation?
Yes, for most vehicles. Because we pre-program it, you can simply install it. In some cases, as noted above, a secondary relearn procedure for the airbag or brake systems may be required by a technician.
How do I find my original BCM part number?
The part number is printed on a sticker on the case of your original BCM. On most GM trucks and SUVs from this era, it’s located under the steering column. On vans and smaller SUVs, it may be in the center dash area.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module.
