Frequently Asked Questions
Do I need to program this module after I receive it?
No. We pre-program the module to the VIN you provide during checkout. This ensures it is ready for immediate installation and operation right out of the box, with no additional dealer visit required.
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body-related electronics. It manages non-engine functions like power windows, door locks, lighting, security systems, wipers, and the HVAC system, ensuring they all work together correctly.
My airbag light is on. Will this fix it?
This module will often resolve airbag light issues caused by a faulty BCM, especially those related to DTC B1001. However, after installation, some vehicles may require a ‘Setup SDM Primary Key’ procedure using a professional scan tool to sync the new BCM with the airbag system and turn off the light.
Where is the BCM located and is it hard to install?
The BCM is typically located under the driver’s side dashboard, near the steering column. For most DIYers with basic tools, the physical installation is straightforward and can often be completed in under 15 minutes.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without needing to send it back to us.
