Before installing your new BCM, take a moment to inspect the main ground connections under the dash and on the driver-side A-pillar. Poor grounds are a common issue on these GM platforms and can cause symptoms that mimic a failed BCM. Ensuring these connections are clean and tight can prevent repeat failures and ensure a successful repair.
Symptoms of a Failing Yukon XL BCM
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ HVAC system failures, such as the blower motor not working or temperature controls being inoperative.
- ✔ The airbag warning light is illuminated, often with a DTC B1001 code stored.
- ✔ Security system malfunctions, leading to no-start conditions or random alarm activation.
- ✔ Intermittent stalling, misfires, or other seemingly unrelated engine performance issues.
- ✔ A variety of diagnostic trouble codes (DTCs) related to body systems and communication errors.

Installation and Post-Install Notes
Installation is straightforward for the average DIYer. The BCM is located under the driver’s side dashboard, near the steering column. In most cases, it’s a simple swap. However, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed using a professional-grade scan tool. 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.
