Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes. By programming the module to your vehicle’s VIN before it ships, we handle the critical step that would otherwise require a dealership visit and specialized tools. For most installations, it is a direct plug-in replacement.
What if my airbag light stays on after installation?
In some cases, if the airbag warning light is on, a procedure called “Setup SDM Primary Key in BCM” must be performed with a professional scan tool. This syncs the new BCM with the airbag system and is a standard GM security procedure.
Do I need to send my old BCM back?
No. We do not require a core return for this part. You can keep your old module, which saves you the hassle and cost of return shipping.
How can I be sure my BCM is the problem?
Common signs of a failing BCM include multiple, unrelated electrical issues (like windows, locks, and HVAC failing at once), security system faults, and specific communication-related DTCs. While this part solves these issues, professional diagnosis is always recommended to confirm the BCM is the root cause.
Where is the BCM located on my vehicle?
On most compatible models like the Silverado, Sierra, and Tahoe, the BCM is located under the steering column on the driver’s side. On Savana and Express vans, it is typically found in the center dash area. Installation usually takes only a few minutes.
