Simple Installation & Post-Install Notes
Installation is straightforward for most DIY mechanics. The BCM is typically located under the steering column or in the center dash area. Once installed, your vehicle’s primary functions will be restored. However, in some cases, minor additional steps may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
There is no core charge for this part, so you can keep your original module. We make the process simple: place your order, provide us with your VIN, and we’ll handle the programming for you.
