Restore Full Electrical Function to Your GM Truck or SUV
Is your Sierra, Silverado, or Escalade plagued by frustrating electrical gremlins? Flickering lights, unresponsive power windows, erratic door locks, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and seemingly unrelated problems. Don’t let a faulty module compromise your vehicle’s reliability and convenience. This direct-replacement BCM is the definitive solution to restore order and get your truck’s features working like new again.
From the Diagnostic Bay
We had a 2013 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would stay on, the radio wouldn’t turn off with the door open, and the power locks worked intermittently. He had already replaced the battery and checked all the fuses. A full diagnostic scan showed multiple communication errors pointing back to one component: the BCM. Instead of a costly trip to the dealership for a new module and programming fees, we installed one of our pre-programmed units. After a quick 15-minute swap and a brake pedal position relearn, every single issue was gone. It’s a perfect example of how this single module can solve a dozen different headaches.
Is Your Vehicle Exhibiting These BCM Failure Symptoms?
- ✔ Intermittent or non-functional power windows, mirrors, or door locks.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ A security system that falsely triggers or prevents the vehicle from starting.
- ✔ Warning lights on the dashboard, such as the airbag or service stabilitrak message.
- ✔ Inoperative remote keyless entry (RKE) fobs.
- ✔ Communication errors when trying to use a diagnostic scan tool.
- ✔ Radio or infotainment system behaving erratically.
The Plug-and-Play Advantage: Programmed to Your VIN
Replacing a BCM isn’t just about swapping hardware. A new module from the dealer comes blank and requires expensive, specialized tools to program it to your vehicle’s specific configuration. We eliminate that entire step. When you order from us, you provide your vehicle’s VIN, and we flash the module with the latest official GM software updates specifically for your truck or SUV. This ensures perfect compatibility with all your vehicle’s options and systems right out of the box. This isn’t just a replacement; it’s a complete, ready-to-install solution for your 2012-2013 Sierra Denali 1500 BCM and many other compatible GM models.
Simple Installation and Post-Install Notes
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Physical installation is straightforward for anyone with basic mechanical skills. After installation, please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation. This also requires a compatible diagnostic tool.
- No Core Charge: You are not required to return your old, faulty module. There is no core charge or deposit associated with this purchase.
This module is a direct replacement for part numbers 22846364, 22737275, and 22846365, ensuring broad compatibility across a range of GM trucks and SUVs from 2012 to 2014.
Frequently Asked Questions
What information do I need to provide after ordering?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We use this to program the BCM with the correct software and vehicle options before shipping.
Is this a difficult part to install myself?
The physical installation is relatively simple, usually involving a few connectors and mounting bolts under the dashboard. However, be prepared for potential post-installation electronic procedures like an airbag sync or brake pedal relearn, which require a professional-grade scan tool.
Will this BCM fix my specific electrical problem?
This module will correct issues directly caused by a faulty BCM. If your vehicle is experiencing problems like erratic lights, non-working power accessories, or security system faults, a failing BCM is the most likely cause.
Do I have to send my old part back?
No. We do not require you to return your original module. This purchase has no core charge.
What if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Does this part replace other part numbers?
Yes, this BCM is a direct replacement for part numbers 22737275, 22846365, and 22846364.
