Frequently Asked Questions
Do I need to do any programming after installation?
No. We pre-program this module to your vehicle’s VIN number before it ships. It is designed to be a plug-and-play installation. In rare cases, if the airbag light remains on, a procedure called “Setup SDM Primary Key in BCM” may need to be performed by a technician with an advanced scan tool.
Where is the BCM located on my truck?
On most compatible models like the Silverado, Sierra, and Tahoe, the Body Control Module is located under the driver’s side dashboard, typically to the left of the steering column. It’s usually accessible after removing the lower dash panel.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of the B1001 code. Replacing the module often resolves this issue. However, if the light persists after installation, the SDM (airbag module) and BCM will need to be synced using a professional diagnostic tool, as mentioned in the post-install procedures.
Is this compatible with other part numbers?
Yes, this module is a direct interchange for a wide range of part numbers, including 25844480, 25971917, 20939137, 22860591, and many others listed in the compatibility data. It is programmed to function correctly for all specified applications.
Do I have to send my old BCM back?
No, there is absolutely no core charge for this part. You can keep your old module without any extra fees or hassle.
