A Veteran Tech’s Pro Tip: After 20 years under the hood, I’ve seen it all. A common mistake is overlooking grounding issues when replacing a BCM. A bad ground can mimic BCM failure and even damage the new unit. Before you plug in your new programmed 25971917 body control module, take five extra minutes to inspect and clean the main BCM ground connection (usually a black wire bolted to the chassis near the module). This simple step can save you hours of headache and ensure your new BCM performs flawlessly for years to come.
Whether you’re getting your Sierra back to the job site or ensuring your Suburban is ready for the family road trip, this programmed 25971917 body control module is the reliable, straightforward solution you need.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and the HVAC system. When it fails, these systems can become erratic or stop working altogether.
Is this BCM difficult to install?
Installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard near the steering column. In most cases, it’s a simple process of disconnecting the battery, unplugging the old module, plugging in the new one, and reconnecting the battery. The entire process often takes less than 15 minutes.
Will I need to go to the dealership after installation?
No. The primary benefit of our service is that we program the module to your vehicle’s VIN before it ships. This eliminates the need for any additional programming or setup at a dealership, saving you time and money.
What if my airbag light is still on after installation?
In some cases, particularly if you had an airbag-related code like B1001, you may need to perform a ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync function that can be done with a professional-grade scan tool and ensures the new BCM is communicating correctly with the airbag system.
Do I need to return my old BCM?
No. We do not require you to return your original module. There is no core charge associated with this part, making the process hassle-free.
