Expert Insight from Our Technicians
“One of the most overlooked steps during a BCM replacement is checking the main ground connections. A corroded or loose ground at the frame or engine block can cause voltage drops that mimic BCM failure, and can even damage a new module over time. Before installing your new, programmed 2013 Sierra 3500 BCM 25823558, take 10 extra minutes to locate, clean, and tighten the main body grounds. This simple step ensures your new BCM has a clean source of power and prevents a frustrating repeat of the same electrical issues.”
Frequently Asked Questions
Does this BCM really not require dealer programming?
That’s correct. We program the module to the VIN you provide during checkout. This ensures it communicates perfectly with your vehicle’s other systems right out of the box, making installation a true plug-and-play process.
What if my airbag light stays on after installation?
In some cases, particularly if DTC B1001 was present, the new BCM needs to be electronically introduced to the airbag system’s SDM (Sensing and Diagnostic Module). This is a simple ‘Setup SDM Primary Key in BCM’ procedure that can be performed with a professional-grade scan tool. It is not a full programming session but a quick sync function.
Where is the BCM located on my truck?
On most compatible GM trucks and SUVs from this era (2007-2013), the Body Control Module is located under the driver’s side of the dashboard, typically to the left of the steering column. Installation usually takes less than 10 minutes.
Is this part compatible with my 2011 Silverado 2500?
Yes, this BCM is compatible with a wide range of GM vehicles, including the 2007-2013 Silverado, Sierra, Tahoe, Yukon, Suburban, and Escalade models. It serves as a direct replacement for numerous part numbers. Please verify your original part number or use the fitment chart to confirm compatibility.
Do I need to send my old BCM back?
No. We do not require a core return for this part. You can keep or dispose of your old module at your convenience, simplifying the repair process for you.
