Frequently Asked Questions
What is VIN programming and why is it important?
VIN programming loads your vehicle’s specific software and settings onto the BCM before it ships. This makes the module ready for installation without needing expensive tools or a trip to the dealer, ensuring all features work correctly.
Is this a difficult part to install?
No, installation is typically very straightforward. The BCM is located under the steering column and can usually be replaced in under 15 minutes with basic hand tools.
Do I need to do anything after installing this BCM?
In most cases, no. However, if your airbag light remains on, a simple ‘Setup SDM Primary Key’ procedure may be needed using a professional scan tool. This syncs the new BCM with the airbag system.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without any hassle or need to return it.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a very common cause of the B1001 code. Replacing it with this programmed module will resolve the fault, though the post-install SDM key setup may be required to clear the light.
