Is Your Avalanche Acting Possessed? Take Back Control.
One minute your 2010 Avalanche 1500 is the reliable truck you count on, the next, the dashboard is lit up like a Christmas tree, the power windows have a mind of their own, and the radio is acting erratically. These aren’t just random glitches; they’re classic signs of a failing Body Control Module (BCM). As the central hub for your truck’s electronics, when the BCM starts to go, it can cause a cascade of frustrating and unpredictable problems.
From the Shop Floor: A Real-World Diagnosis
“Just last month, a customer brought in his 2010 Avalanche with a bizarre set of symptoms. The interior lights would flicker, the door locks would cycle while driving, and he kept getting a ‘Service 4WD’ message, even though the 4×4 system seemed fine. He’d already replaced the battery and checked the main grounds. After hooking up the scan tool, we found multiple communication loss codes pointing to the BCM. A faulty Body Control Module was creating network interference, causing all the other modules to report errors. We swapped in a VIN-programmed BCM, and every single issue vanished. It’s a repair I’ve done hundreds of times on these GMT900 platform trucks.”
The Direct Solution: A VIN-Programmed 2010 Avalanche 1500 BCM
Don’t let a faulty module sideline your truck. This Body Control Module, part number 25892622, is the definitive solution. We take the guesswork and dealer hassle out of the equation. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specifically for your 2010 Avalanche 1500. It arrives at your door ready for installation, saving you from expensive dealership programming fees and towing costs.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, door locks, or mirrors operating intermittently
- ✔ Security system faults or the vehicle refusing to start
- ✔ False warning lights on the instrument cluster (e.g., Airbag, ABS, Service 4WD)
- ✔ Radio or climate control malfunctions
- ✔ Communication errors with diagnostic scan tools
Installation & Post-Install Procedures
Installing your new BCM is straightforward. On the 2010 Avalanche, it’s typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative battery terminal and wait 10-15 minutes before beginning work on any electronic components.
- Locate the BCM: Remove the necessary lower dash panels to access the module.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that must be depressed. Then, unbolt the old module from its bracket.
- Install the New Module: Seat the new BCM in the bracket, reconnect all electrical connectors firmly until they click, and reinstall the dash panels.
- Reconnect Battery: Reattach the negative battery terminal.
CRITICAL Post-Installation Steps
This is not an optional step. To ensure full functionality and safety, certain relearn procedures must be performed with a compatible, high-level diagnostic scan tool after the BCM is installed:
- Airbag System (SRS): You must perform the ‘Setup SDM Primary Key in BCM’ procedure. Failure to do so will leave the airbag warning light on, and the system will be inoperative.
- Brake Pedal Position Sensor: Some vehicles require a recalibration of the brake pedal position sensor to ensure proper brake light operation and stability control function.
If you are not equipped to perform these procedures, we strongly recommend seeking assistance from a qualified professional technician.
