Installation and Post-Install Notes
Installation is straightforward for the average DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. The process usually takes less than 15 minutes. However, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure 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 correct brake light and traction control operation.
By choosing our Programmed GM BCM, you are getting a reliable, cost-effective repair that will solve your vehicle’s electrical gremlins and restore its proper function. No core charge means you can keep your old part, saving you time and money.
