Installation & Post-Install Notes
Installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes only a few minutes. However, please be aware of potential post-installation procedures. While our VIN programming handles the majority of the setup, some vehicles may require an ‘SDM Key Relearn’ using a professional scan tool if the airbag light remains on. Additionally, a Brake Pedal Position Sensor relearn may be necessary on certain models. There is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does a Body Control Module do on a Chevy Tahoe?
The BCM is a computer that controls most of your Tahoe’s non-engine related electronics. This includes the power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC climate controls.
Will I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. This makes it ready for installation right out of the box, saving you time and money on dealership programming fees.
Is this part difficult to install?
The physical installation is relatively simple for most DIYers. It’s located under the driver’s side dash and involves unplugging the old module and plugging in the new one. The entire process can often be completed in under 15 minutes.
What if my airbag light is on after installation?
If the airbag light persists, your vehicle may require a ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system and must be performed with a professional-grade diagnostic tool.
Do I need to return my old BCM?
No, there is no core charge or need to return your original part. You can keep it or dispose of it at your convenience.
