Expert Insight: The Importance of VIN Programming
As veteran technicians, we see customers who buy used, non-programmed BCMs hoping for a cheap fix, only to find their vehicle won’t start or has even more electrical issues. A BCM is not a one-size-fits-all part; it’s coded specifically to your truck’s unique features and security system. Our VIN programming service isn’t just a convenience—it’s essential for a successful repair. We load the latest GM software for your vehicle, ensuring all systems communicate correctly from the moment you plug it in. This is the difference between a 5-minute fix and a week-long headache.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC (heating and air conditioning) system.
Is this BCM difficult to install?
Installation is typically straightforward for someone with basic automotive skills. The BCM is usually located under the driver’s side dashboard near the steering column. Because our module comes pre-programmed, the physical replacement is a simple plug-and-play process that often takes less than 15 minutes.
Why is my airbag light still on after installation?
In some cases, particularly with airbag code B1001, an additional procedure called ‘Setup SDM Primary Key in BCM’ is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and must be done with a professional-grade scan tool. This is a security feature, not a defect in the part.
Do I need to send my old module back?
No. We do not require a core return. You can keep or dispose of your old part, saving you the hassle and cost of shipping it back to us.
