Installation and System Syncing
The BCM is typically located under the driver’s side dashboard near the steering column, making physical replacement a quick job. After installation, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag warning light is illuminated. This is not a defect but a necessary security handshake between the new BCM and the airbag system, which must be completed with a professional-grade scan tool. Additionally, a Brake Pedal Position relearn may be needed. Always consult a factory service manual for your specific model’s requirements.

Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic systems, such as power windows, locks, lights, wipers, security system, and climate controls.
Will I need to take my truck to the dealer after installing this?
No. We pre-program the module to your vehicle’s VIN, so it’s ready for installation right out of the box, saving you a trip to the dealership for programming.
Where is the BCM located on a 2008 Silverado or Tahoe?
On most compatible GM trucks and SUVs from this era, the BCM is located under the driver-side dashboard, often to the left of the steering column.
My airbag light turned on after I installed the new BCM. Is it broken?
No, the module is not broken. This is a normal security procedure. You will need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function to sync the new BCM with the airbag system and turn off the light.
What does ‘No Core Charge’ mean?
It means you do not have to return your old, faulty BCM to us. You can keep it or dispose of it yourself, saving you the hassle and cost of return shipping.
