Expert Insight: The Importance of a Good Ground
As a veteran technician, I’ve seen countless electrical issues caused by something as simple as a poor ground connection. Before you condemn your old BCM, and especially after installing your new one, take a moment to locate and inspect the main body ground straps under the dash and in the engine bay. A loose, corroded, or broken ground can cause the exact same symptoms as a failed module. Ensuring these connections are clean and tight is a crucial step that prevents recurring problems and ensures your new 25971916 Body Control Module performs flawlessly for years to come.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle the programming for you. This module is shipped pre-programmed to your vehicle’s VIN, making it ready for installation right out of the box. This saves you a costly trip to the dealership.
Where is the Body Control Module located on my vehicle?
On most compatible GM trucks and SUVs from this era, the BCM is located under the driver’s side of the dashboard, typically near the steering column. Installation is straightforward and usually takes just a few minutes with basic tools.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without the hassle of needing to return it.
What if my airbag light is still on after installation?
If the airbag warning light persists after installation (often with DTC B1001), it means the new BCM needs to be synced with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed with a professional-grade bidirectional scan tool.
Will this fix my specific electrical problem?
This module is the central controller for most non-engine related electronics. If you are experiencing issues with power windows, locks, lights, HVAC, or security systems, a faulty BCM is the most common cause. This part is designed to be a direct solution for those failures.
