Expert Insight: Why VIN Programming is Non-Negotiable
From over 20 years of hands-on diagnostics, I can tell you that a BCM is not a ‘one-size-fits-all’ part. Each vehicle has a unique configuration of options—from the type of radio it has to whether it has power-folding mirrors. The VIN programming process tailors the BCM to your exact build sheet. Installing a non-programmed module from a junkyard or another vehicle will, at best, result in features not working, and at worst, can prevent the vehicle from starting at all. Our pre-programming service takes all the guesswork and risk out of the repair, ensuring the job gets done right the first time. The **Programmed GM Body Control Module 20815898** is a professional-grade repair made simple.
Frequently Asked Questions
Do I need to send you my old BCM?
No. There is no core charge for this part. You can keep your original module.
What information do you need from me to program the module?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This allows us to flash the module with the exact software and configuration for your specific vehicle.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. However, its location varies by model (e.g., under the dash, behind the glove box). Because it arrives pre-programmed, you avoid the most difficult part of the job. We always recommend consulting a service manual for your specific vehicle’s procedure. The **Programmed GM Body Control Module 20815898** simplifies the process significantly.
Will any other steps be required after installation?
In some cases, yes. Depending on your vehicle, a ‘Brake Pedal Position Relearn’ or an ‘Airbag System Sync’ (if the airbag light comes on) may need to be performed with a professional scan tool. These are standard post-replacement procedures for many modern vehicles.
How do I know if this part number will fit my vehicle?
This module replaces a long list of original GM part numbers. Please check the comprehensive list provided in the description to confirm that your original part number is included, or that your specific year, make, and model are listed as compatible.
