Installation and Post-Install Notes
Installation is straightforward for those with mechanical experience. On the 2010 Escalade ESV, the BCM is typically located under the steering column. While our VIN programming handles the majority of the setup, some vehicles may require additional relearn procedures after installation. Specifically, if your airbag warning light is on, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary to ensure proper brake light and traction control operation. Always consult a factory service manual for detailed instructions specific to your vehicle.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic functions not related to the engine, such as power windows, locks, lights, security system, wipers, and more. It acts as a central hub for these systems.
Do I need to program this BCM?
No. We program the module for you before it ships. You must provide your vehicle’s 17-digit VIN at checkout so we can load the correct software and vehicle-specific settings for a simple installation.
What happens if I forget to provide my VIN?
To prevent shipping delays, it is crucial to provide your VIN when you place your order. We cannot program or ship the module without it, as it will not function correctly in your vehicle.
Why is my airbag light on after installing the new BCM?
This can happen because the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool to sync the modules and turn off the light.
Is this a difficult part to replace?
For the 2010 Escalade ESV, the BCM is located under the driver’s side dash. While physically swapping the module is manageable for a DIYer with basic tools, some post-installation relearn procedures may require a scan tool.
Does this part require me to send my old one back?
No, there is no core charge for this part. You can keep your original module.
