Restore Full Electrical Function to Your GM Vehicle
Is your Chevrolet, GMC, Buick, or Cadillac plagued by frustrating electrical gremlins? Flickering lights, unresponsive power windows, a security system that acts on its own, or a mysterious battery drain can often be traced back to a single, critical component: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of confusing and disruptive problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and reliability. Don’t let a faulty module dictate your driving experience. Take control with our direct-fit, pre-programmed solution.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle’s security system or keyless entry malfunctioning.
- ✔ Horn honking unexpectedly or not working when needed.
- ✔ Wipers activating on their own or failing to turn on.
- ✔ Unexplained parasitic battery drain that leaves you stranded.
- ✔ False warning lights appearing on the instrument cluster.
From the Diagnostic Bay
We had a 2015 Chevy Traverse come into the shop with a classic case of BCM failure. The customer complained of a dead battery every morning and said the dash lights would sometimes flicker randomly after shutting the vehicle off. We checked the battery and alternator, which were both fine. A parasitic draw test pointed to a significant power drain. After isolating circuits, we traced the issue to the BCM, which wasn’t properly entering its ‘sleep’ mode. It was keeping other modules awake all night, draining the battery. Replacing the old unit with a properly programmed GM Body Control Module 22820314 solved the problem completely. The customer was thrilled to have a reliable vehicle again without the morning dread of a no-start condition.
Why Choose Our Pre-Programmed GM Body Control Module 22820314?
The biggest hurdle in replacing a modern BCM is the need for expensive, vehicle-specific programming. A new module from the dealership is essentially a blank slate and requires specialized tools to link it to your vehicle’s VIN and options. Our service completely eliminates this step. We take the hassle and high cost out of the repair by programming the module for you before it ships. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the unit with the latest, most stable software directly from GM. This ensures that the module is a true plug-and-play solution, ready for installation right out of the box.
Installation and Post-Install Procedures
Installation is straightforward for anyone with basic mechanical skills. The BCM is typically located under the driver’s side dashboard. Once installed, the module will restore control over your vehicle’s body functions. However, in some vehicles, additional synchronization steps may be required. These are not defects but are part of the vehicle’s security and safety systems handshaking with the new module.
- Airbag System Sync: If the airbag warning light is on 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’s Supplemental Deployable Module (SDM).
- Brake Pedal Position Relearn: To ensure correct brake light operation and traction control performance, a brake pedal position sensor recalibration might be necessary. This can also be done with a compatible diagnostic tool.
This GM Body Control Module 22820314 is a direct replacement for part numbers 22820314 and 22915542, ensuring perfect compatibility for a wide range of vehicles including the Chevrolet Traverse, GMC Acadia, Buick Enclave, Cadillac CTS, and Express/Savana work vans. Please verify your part number and check the fitment list to confirm compatibility.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. It arrives ready to be installed, saving you hundreds in dealership fees and programming costs.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional diagnostic scan tool, such as a GM Tech 2, MDI, or equivalent high-end scanner. Many local repair shops have this equipment.
Is this part difficult to install?
The physical installation is generally straightforward for a DIYer with some experience. The BCM is usually located under the driver’s side dash. The main challenge is accessing it. We always recommend consulting a service manual for your specific vehicle.
Will this fix my car’s specific electrical problem?
This module will correct issues directly caused by a faulty BCM. If your vehicle exhibits symptoms like erratic lights, malfunctioning power accessories, security system faults, or a parasitic battery drain traced to the BCM, this part is the correct solution.
