Restore Your Truck’s Brain & End Electrical Frustration
Are you chasing electrical gremlins in your 2002 GM truck or SUV? Flickering lights, malfunctioning power windows and locks, a security system that has a mind of its own, or strange warning messages on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and frustrating problems. This isn’t just an annoyance; it can affect vehicle security and the proper function of safety features. Stop guessing with fuses and relays—get the direct-fit, reliable solution.
We solve the biggest hurdle in BCM replacement: programming. This module arrives at your door pre-programmed with the latest official GM software, tailored specifically to your vehicle’s VIN. This means you can bypass the expensive trip to the dealership for programming. It’s a straightforward solution designed for both savvy DIYers and professional technicians who value efficiency.
Is Your Truck Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution for your 2002 GM vehicle.
- ✔ Erratic or non-functional power windows, door locks, and interior lights.
- ✔ The security or anti-theft light stays on, or the vehicle won’t start.
- ✔ Dashboard gauges behaving erratically or not working at all.
- ✔ The radio or climate control system turns on and off randomly.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U1000, U1016, or other U-codes.
- ✔ Horn honking unexpectedly or not working when pressed.
A Straightforward Guide to Installation
Replacing the BCM is a manageable job for most DIY enthusiasts. The module is typically located under the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- Locate the BCM: On most 2002 GM trucks and SUVs, the BCM is mounted to a bracket or panel beneath the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting location.
- Install the New Module: Mount your new, pre-programmed BCM in the same position as the old one. Securely plug in all the electrical connectors, ensuring they click into place.
- Reconnect Power: Re-attach the negative battery terminal. Turn the key to the ‘On’ position and verify that your power accessories are now functioning correctly.
Important Post-Installation Information
Because this 2002 Escalade BCM is pre-programmed, most functions will work immediately. However, depending on your vehicle’s specific configuration, a couple of simple relearn procedures may be needed.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag module and must be performed with a bi-directional scan tool. This is only necessary if the light is on.
- Brake Pedal Position (BPP) Relearn: Some models may require a BPP sensor relearn to ensure correct brake light operation and stability control function. This procedure can often be done with a capable diagnostic tool.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the biggest benefit of our service. We program the module to your vehicle’s specific VIN before we ship it. It arrives ready for installation, saving you time and money.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information to program it correctly for your truck.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more.
What if my airbag light comes on after I install it?
This is uncommon, but if it happens, it means the new BCM needs to be electronically introduced to the airbag system (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be done by a repair shop with a professional-grade scan tool.
Is there a core charge?
No, there is no core charge for this part. You can keep your old, non-functional module without needing to send it back.
