Installation & Post-Install Notes
Installation is straightforward for a DIYer with basic tools. The BCM is typically located under the driver’s side dashboard, near the steering column. While the module is plug-and-play for most functions, please note the following potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
For a reliable and permanent fix for your vehicle’s electrical system, this programmed 2011 Sierra Denali BCM is the ideal choice.
