Frequently Asked Questions
Is this BCM difficult to install?
No, the installation is straightforward for someone with basic mechanical skills. The BCM is typically located under the driver’s side dashboard near the steering column. The physical replacement often takes less than 10 minutes. Since it comes pre-programmed, no special computer is needed for the initial setup.
What if my airbag light stays on after installation?
In some cases, particularly if you had an airbag code like B1001, the new BCM needs to be synced with the airbag system’s SDM (Sensing and Diagnostic Module). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick sync process that a qualified mechanic can perform.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and expense of return shipping.
How do I know if this part number is correct for my truck?
This module, 25844480, is a direct replacement for many part numbers, including 25971916. The best way to confirm is to check the part number on your original BCM. This part is confirmed to fit the 2013 Silverado 3500 Body Control Module application, as well as many other GM models listed in the compatibility chart.
Will this fix my check engine light?
A BCM typically controls body functions, not engine performance. While it can cause no-start issues related to the security system, it is unlikely to be the cause of a check engine light related to emissions or engine management. Always diagnose check engine codes separately.
