Expert Insight: Check Your Grounds First
Before replacing your 2013 GMC Sierra 3500 BCM, take a moment to inspect the main grounding points, especially the one located on the frame beneath the driver’s door. On work trucks like the Sierra, these grounds are exposed to harsh conditions and can corrode over time. A poor ground can cause many of the same symptoms as a failed BCM. Cleaning this connection is a quick, five-minute check that can sometimes solve the problem and will ensure your new module has a solid connection to perform reliably for years to come.
Don’t let a faulty module compromise the reliability of your truck. By installing this pre-programmed 2013 GMC Sierra 3500 BCM, you are not just replacing a part; you are restoring the core dependability your vehicle was built for. Order today and get back to work with confidence.
Frequently Asked Questions
Do I need to have the dealership program this BCM?
No. We pre-program the module to your vehicle’s VIN before shipping it to you. This allows for a simple, plug-and-play installation without any need for additional dealer tools or programming fees.
Is this a difficult part to install myself?
For most experienced DIYers, the installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. It usually takes less than 15 minutes to swap out. However, always disconnect the battery before starting work on any electronic components.
What if my airbag light stays on after installation?
In some cases, particularly if you had an airbag code like B1001, the new BCM may need to be synced with the airbag system’s SDM. This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed with a professional-grade scan tool. This is not a programming step, but a security handshake between modules.
What does “no core charge” mean?
It means you do not have to send your old, faulty BCM back to us. You can keep it, dispose of it, or recycle it at your convenience without any additional fees or deposits.
Will this BCM fix my specific issue?
This module is the direct solution for a very wide range of electrical issues controlled by the BCM, including those listed in the description. If your vehicle has been properly diagnosed with a failing Body Control Module, this part is designed to resolve those symptoms and restore proper function.
