Simple Installation Process
Installation is straightforward for the average DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the negative battery terminal, remove the lower dash panel for access, unplug the electrical connectors from the old module, and swap in the new one. In most cases, the job takes less than 15 minutes. Please note that on some vehicles, post-installation procedures may be required. If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary. These procedures ensure all related safety systems are correctly calibrated to the new module.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
What does ‘VIN Programmed’ mean for me?
‘VIN Programmed’ means we load your vehicle’s specific Vehicle Identification Number (VIN) and factory options onto the module before we ship it. This makes the installation plug-and-play, saving you a trip to the dealership and avoiding hundreds of dollars in programming fees.
Where is the BCM located on my 2008 Silverado?
On most 2007-2013 GM trucks and SUVs like the Silverado, Sierra, and Tahoe, the BCM is located under the driver’s side of the dashboard, usually to the left of the steering column.
Will I need to perform any procedures after installation?
In many cases, no. However, if your airbag warning light is on after installation, a ‘Setup SDM Primary Key’ procedure is required using a professional scan tool. A brake pedal position relearn may also be necessary on certain models to ensure proper brake light and traction control operation.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back, making the process hassle-free.
