Restore Full Electrical Function to Your GM Vehicle
Are you experiencing bizarre electrical problems in your 2010 Avalanche or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or warning lights that won’t turn off are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s electronic accessories, and when it fails, it can cause a wide range of frustrating and unpredictable problems. This replacement module is the reliable, straightforward solution to get your truck or SUV back in top condition.
From the Diagnostic Bay
We had a 2010 Tahoe come in that was driving the owner crazy. The radio would randomly shut off, the dome lights would stay on, and the key fob worked only intermittently. He’d already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of a costly and time-consuming trip to the dealer, we installed one of our VIN-programmed BCMs. The installation was simple, and all the strange electrical gremlins vanished immediately. It’s a common failure, but thankfully, an easy fix.
Why Choose Our 2010 Avalanche Body Control Module?
This isn’t just a replacement part; it’s a complete solution. We take the guesswork and hassle out of the repair process. Each module is professionally programmed with the latest GM software updates specifically for your vehicle using the VIN you provide. This critical step ensures that the BCM communicates correctly with all other modules in your vehicle, restoring factory functionality without requiring a trip to the dealership for expensive programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system acting up or preventing the engine from starting.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Dashboard warning lights (like ABS or Airbag) staying illuminated.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Rapid battery drain while the vehicle is off.
Installation and Post-Install Procedures
Installation is a direct replacement for your original module. However, due to the complexity of modern vehicle systems, a few additional steps may be required after the part is installed. In most cases, the vehicle will operate correctly immediately. If you notice an airbag warning light, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic body accessories. This includes power windows, locks, lights, wipers, the security system, and more.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will program the module with this information before shipping it to you, ensuring it’s ready for installation.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the physical replacement is typically straightforward, often located under the dash. The key is that our pre-programming service eliminates the most difficult step, which is software flashing. Some post-install relearn procedures may still be needed.
What happens if the airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be synced with the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be performed by a repair shop with a professional-grade diagnostic tool.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
