Is Your GM Truck Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows with a mind of their own, or a dashboard that lights up with random warnings? These frustrating and often intermittent issues are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, managing everything from your interior lights and power locks to the security system. When it starts to fail, it can create a cascade of confusing and unpredictable problems.
Common Symptoms of a Failing BCM
- ✔️ Power windows, mirrors, or locks operating erratically or not at all.
- ✔️ Interior or exterior lights (headlights, taillights, dome lights) staying on or not turning on.
- ✔️ Horn honking unexpectedly or not working.
- ✔️ Key fob failing to lock or unlock the doors.
- ✔️ Vehicle security system faults or anti-theft light flashing, preventing the truck from starting.
- ✔️ Inaccurate readings or warning lights on the instrument cluster.
- ✔️ HVAC (A/C and heat) controls not responding correctly.

Installation and Post-Install Notes
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While installation is straightforward for those with mechanical experience, some post-installation procedures may be necessary depending on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper function of the brake lights and stability control systems.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What does a Body Control Module do on my truck?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine-related electronic functions. This includes power windows, locks, lights, wipers, security system, and more. It acts as a central hub for these systems.
Is this module difficult to install?
The physical installation is typically simple, involving unplugging connectors and removing a few bolts. It’s located under the driver’s side dashboard. The key benefit of our product is that the complex programming is already done for you.
Do I need to get this programmed by a dealer?
No. This is the primary benefit of our service. We program the BCM to your vehicle’s VIN before we ship it. It arrives ready to be installed, saving you time and the high cost of dealership programming.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is crucial for us to program the module correctly for your truck’s specific options and features.
What if my airbag light is on after I install it?
This can happen. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
