Easy Installation Guide
Replacing the BCM in your 2015 GMC Sierra Denali 3500 takes about 30 minutes with basic tools. Locate it under the steering column—disconnect the battery first to avoid shorts.
- Remove the lower dash panel and unplug connectors from the old BCM.
- Install the new unit, reconnect, and secure it.
- Reconnect the battery and perform relearn procedures.
For GM vehicles, theft relearn activates only if no-start happens post-install. Cycle the key: Turn to ON for 10 minutes, off for 5 seconds, repeat three times. Additionally, reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ with a scan tool like Tech2 or equivalent. Some models need brake pedal recalibration for safety—use a diagnostic tool to align sensors, ensuring smooth braking. Steps vary, so check your manual or consult a tech if unsure.
