Are you battling frustrating electrical problems in your GM truck or SUV? A faulty Body Control Module, or BCM, is often the culprit behind a host of issues that can seem random and unrelated. From power windows that won’t cooperate to a security light that prevents your vehicle from starting, a failing BCM can disrupt your vehicle’s core functions. This replacement Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN with the latest GM software updates. This eliminates the need for expensive dealership programming, getting you back on the road faster.
We had a 2002 Chevy Silverado in the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome light would flicker, and occasionally the horn would honk when he used the turn signal. He had already replaced the battery and checked all the fuses. We suspected the BCM, and after plugging in our diagnostic tool, we saw communication errors across multiple systems all pointing back to it. Installing a VIN-programmed BCM like this one solved every single issue. It’s the central nervous system for the vehicle’s accessories, and when it fails, things get weird fast.
Is Your GM Vehicle Showing These BCM Failure Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security or anti-theft system light is on, possibly causing a no-start condition.
- ✔ The horn sounds unexpectedly or doesn’t work when prompted.
- ✔ Wipers operate intermittently or get stuck in one position.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Communication error codes stored when scanned with a diagnostic tool.

Important Installation Notes
While this module is designed for straightforward installation, some vehicles may require additional steps after the part is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light illuminates after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function correctly.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
Do I need to program this BCM?
No. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready for installation, loaded with the latest GM software.
Where is the BCM located on a 2002 GMC Sierra?
On most 2002 GM full-size trucks and SUVs like the Sierra, Silverado, and Tahoe, the BCM is located under the driver’s side of the dashboard, near the steering column.
What should I do if my airbag light is on after installation?
If the airbag light is on, the BCM needs to be synced with the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be done by a mechanic with a professional diagnostic tool.
Is this part completely plug-and-play?
It is mostly plug-and-play because the main programming is done for you. However, as with any module replacement, some simple relearn procedures for systems like the brake pedal position sensor may be required depending on your specific model.
What part numbers does this BCM replace?
This module is a direct replacement for the following GM part numbers: 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU.
