Is Your 2010 Chevy Avalanche Experiencing Bizarre Electrical Problems?

If your truck’s lights are flickering, power windows and locks are acting erratically, or you’re seeing strange warning messages on the dash, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, managing everything from the interior lights and security system to the power door locks. When it fails, it can cause a host of frustrating and unpredictable issues that can be difficult to diagnose.

From the Diagnostic Bay
We had a 2010 Tahoe in the shop last month with a classic case of BCM failure. The customer complained that sometimes the radio wouldn’t turn off after opening the door, the dome lights would stay on, and occasionally the truck wouldn’t start at all. We checked the battery and alternator, which were fine. After connecting our scan tool, we saw multiple communication errors pointing directly to the BCM. Replacing it with a pre-programmed unit like this one resolved all the ghost-in-the-machine problems instantly, saving the customer a costly trip to the dealership for diagnostics and programming.

Symptoms of a Failing 2010 Avalanche BCM

  • ✔ Intermittent or non-functional power windows, mirrors, or door locks.
  • ✔ Dash lights flickering or warning lights staying on for no reason (ABS, Airbag, Security).
  • ✔ The security system preventing the vehicle from starting.
  • ✔ Interior or exterior lights not working correctly.
  • ✔ Radio or infotainment system behaving erratically.
  • ✔ Key fob not responding or working intermittently.

The Direct-Fit, Programmed Solution

This Body Control Module is the definitive solution for your vehicle’s electrical woes. We take the guesswork and hassle out of the repair. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specific to your 2010 Avalanche 1500. This means no expensive trips to the dealer for programming. It arrives at your door ready for installation. While the physical installation is straightforward, please be aware of potential post-installation procedures.

Post-Installation Requirements

After installing your new BCM, some vehicles may require additional steps to ensure all systems communicate correctly. This can include an Airbag System Sync if the airbag light is illuminated, which requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a Brake Pedal Position Relearn may be necessary for proper brake light and traction control function. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions

What does the Body Control Module (BCM) do?

The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls features like power windows, locks, lights, the security system, and the instrument cluster.

Do I need to get this BCM programmed by a dealer?

No. We program the module to your vehicle’s specific VIN before shipping it to you. This saves you time and money, eliminating the need for a dealership visit for programming.

Is this part difficult to install?

The physical replacement is typically straightforward, often located under the dash or steering column. However, some vehicles may require post-installation relearn procedures for systems like the airbags or brakes, which may require a professional scan tool.

How do I provide my VIN number?

You can enter your vehicle’s 17-digit VIN in the notes section during checkout, or we will contact you via email after your purchase to request it. We cannot ship your part until we have programmed it.

What if the airbag light is on after I install the BCM?

If the airbag light illuminates, it means the BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be performed by a qualified technician with a high-level diagnostic tool.

Is there a core charge for my old part?

No, there is no core charge. You can keep your original module.
