Installation and Post-Install Notes
The BCM is typically located under the driver’s side dashboard, near the steering column, making physical installation a straightforward process that often takes less than 15 minutes. However, after installing your new 2007-2011 Avalanche BCM, be aware of a few potential procedures. If the airbag warning light is illuminated, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ function to sync the systems. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. Always consult a factory service manual for procedures specific to your vehicle.
Frequently Asked Questions
What does the Body Control Module do on my 2007-2011 Avalanche?
The BCM acts as the main computer for your truck’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This allows for a simple plug-and-play installation without the need for expensive dealership programming tools.
What if my airbag light is on after I install the new BCM?
This is a common security measure. You will need a professional-grade scan tool to perform a procedure called ‘Setup SDM Primary Key in BCM’. This syncs the new BCM with your vehicle’s airbag system and will turn off the light.
Is this part compatible with other GM trucks and SUVs?
Yes, this BCM is compatible with a wide range of 2007-2013 GM vehicles, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade. It interchanges with numerous part numbers like 25844480, 25971917, and 20939137.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. You can keep it or dispose of it yourself, which saves you the time, hassle, and expense of a core return.
