Is Your GM Truck or SUV Experiencing Bizarre Electrical Problems?
If your 2002 Cadillac Escalade, Silverado, Tahoe, or another compatible GM vehicle is suffering from strange electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from the power windows and door locks to the interior lights and security system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems.
This is a direct-replacement Body Control Module for part number 15063578 and other interchangeable numbers. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific VIN. This means no expensive trips to the dealership for coding. It arrives at your door ready for installation, loaded with the latest software updates from GM to ensure optimal performance and reliability.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-working power windows and door locks
- ✔ Interior or exterior lights staying on or not turning on at all
- ✔ The security system engaging randomly or preventing the vehicle from starting
- ✔ The ‘Service Security System’ or other warning messages on the instrument cluster
- ✔ Intermittent radio or climate control operation
- ✔ Communication problems with diagnostic scan tools

Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control function.
There is no core charge for this part. You can keep your old module.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls your vehicle’s body-related electronic accessories, such as power windows, locks, lights, wipers, security system, and more. It ensures all these features work together correctly.
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready to install with the latest GM software.
Where is the BCM located on my 2002 Escalade or Silverado?
On most 2002 GM full-size trucks and SUVs like the Escalade, Silverado, and Tahoe, the BCM is located under the steering column, to the left of the brake pedal. On vans like the Astro/Safari or smaller trucks like the S10/Blazer, it’s often found behind the center of the dashboard.
What if the airbag light comes on after I install it?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix the ‘Service Security System’ message?
Yes, a faulty BCM is one of the most common causes of a persistent ‘Service Security System’ message and related starting issues. Replacing it with our pre-programmed unit will typically resolve this problem.
