A Technician’s Tip: Check Your Grounds
From over 20 years in the garage, I’ve seen countless BCMs replaced only for the problem to return. Why? A bad ground. The BCM is extremely sensitive to voltage fluctuations. Before installing your new module, take 10 extra minutes to check the main body and chassis ground connections, especially the one near the BCM’s location under the dash. A clean, tight ground is the best insurance for your new part and can prevent future headaches. It’s a simple step that makes a world of difference.
Don’t let a faulty BCM compromise the performance and reliability of your truck. This programmed 2013 Sierra Denali 3500 Body Control Module is the most efficient way to solve the problem correctly the first time. It’s the same high-quality component you’d get from a dealer, but without the extra cost and hassle of post-installation programming.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s non-engine related electronics. It controls functions like your interior and exterior lights, power windows and locks, security system, wipers, and climate control system, ensuring they all work together as intended.
Is this module truly ‘plug-and-play’?
Yes. We program the module to your vehicle’s VIN before shipping. This means it’s ready for installation right out of the box, with no need for a trip to the dealership for additional programming. In some cases, an airbag light may require a simple sync procedure with a professional scan tool, as noted in our installation tips.
Where is the BCM located on my 2013 Sierra Denali 3500?
The BCM is typically located under the driver’s side dashboard, near the steering column. Installation usually takes less than 15 minutes with basic hand tools, making it a very manageable DIY repair for many owners.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of an airbag light with DTC B1001. Replacing it with this programmed unit should resolve the root cause. However, after installation, you may need to perform a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool to sync the new BCM with the airbag system and clear the light.
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 hassle of packaging and shipping it back to us.
