Restore Your Truck’s Electrical Functions with a VIN-Programmed BCM
Are you battling frustrating electrical gremlins in your Chevrolet Avalanche, Silverado, or GMC Sierra? Issues like flickering lights, non-responsive power windows and locks, or a security system that has a mind of its own are often traced back to a single, critical component: the Body Control Module (BCM). The BCM acts as the central hub for your truck’s body electronics, and when it fails, it can cause a cascade of seemingly unrelated problems. This replacement Body Control Module, compatible with part number 22846364, is the definitive solution to restore your vehicle’s functionality and reliability.
Is Your GM Truck Showing Signs of BCM Failure?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, a faulty Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights, headlights, or taillights staying on, flickering, or failing to illuminate.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Security system malfunctions, including false alarms or anti-theft systems preventing the engine from starting.
- ✔ Erratic instrument cluster behavior or warning lights (like ABS or Airbag) appearing without cause.
- ✔ Radio, navigation, or infotainment system glitches and power issues.
- ✔ Climate control and A/C blower motor problems.
- ✔ A persistent parasitic battery drain that leaves you with a dead battery, even after short periods.
The Simple Solution: A Pre-Programmed 2012-2013 Avalanche BCM
Replacing a BCM used to mean a costly trip to the dealership for installation and programming. We eliminate that hassle. When you order from us, we use the Vehicle Identification Number (VIN) you provide to program the module with the latest, most stable GM factory software specifically for your truck’s configuration. This ensures that all your vehicle’s options are recognized and function correctly right out of the box. This module is a direct replacement for part numbers 22846364, 22737275, and 22846365, making it a versatile solution for a wide range of GM trucks and SUVs.
Installation and Post-Install Procedures
The BCM is typically located under the driver’s side dashboard, near the steering column. Installation involves disconnecting the battery and carefully swapping the electrical connectors from the old module to the new one. While our programming makes this a near plug-and-play process, some vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light is on 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 recalibration may be necessary to ensure proper brake light and traction control operation.
Best of all, there is no core charge for this part. You can keep your original module without the hassle of shipping it back.
Frequently Asked Questions
Why do I need to provide my vehicle’s VIN?
Your VIN allows us to program the BCM with the exact software and settings for your vehicle’s specific features and options. This ensures seamless integration and prevents compatibility issues that would otherwise require a trip to the dealer.
Is this BCM difficult to install myself?
The physical installation is straightforward for someone with basic mechanical skills, as it’s typically located under the steering column and involves swapping connectors. However, be aware that post-installation procedures like an airbag sync may require a professional scan tool.
My original part number is 22737275. Will this module work?
Yes. This BCM, part number 22846364, is a direct, interchangeable replacement for part numbers 22737275 and 22846365. We will program it to function perfectly in your vehicle.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be synchronized with your vehicle’s Sensing and Diagnostic Module (SDM). A qualified technician with a high-level diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I have to send my old BCM back?
No. We do not require a core return for this part. You can keep your original module.
