Are you battling frustrating electrical issues in your Chevrolet Suburban 2500? A faulty Body Control Module (BCM) is often the culprit behind problems like erratic lights, malfunctioning power windows, a dead instrument cluster, or even a no-start condition. This OEM-quality replacement BCM, part number 15137393, is the definitive solution to restore your vehicle’s electronic systems to perfect working order. As the central command for your truck’s body electronics, a functioning BCM is critical for safety, security, and convenience.
This module arrives expertly programmed to your vehicle’s specific VIN, eliminating the need for expensive and time-consuming trips to the dealership for programming. This plug-and-play design ensures a seamless installation process, getting you back on the road quickly. Simply provide your VIN at checkout, and we handle the rest, loading the latest GM software updates for optimal performance and compatibility.
We had a 2005 Suburban 2500 come in with the strangest set of symptoms. The radio would turn on by itself, the driver’s side power window wouldn’t work, and the security light was flashing intermittently, preventing the truck from starting. The owner had already replaced the window motor and the battery, with no success. After a quick scan, we saw multiple communication codes pointing to the BCM. Instead of more guesswork, we installed a VIN-programmed module. In under 10 minutes, every single issue was resolved. It’s a classic case of the BCM being the hidden source of multiple, seemingly unrelated electrical gremlins.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means this Body Control Module is a true plug-and-play solution. We pre-load it with your vehicle’s specific VIN and the latest GM software before shipping. This saves you a trip to the dealership and avoids the high cost of their programming services.
Is this BCM difficult to install?
No, installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. It’s held in by a few clips or bolts and has several electrical connectors. Most people can swap it out in under 15 minutes with basic tools.
What happens if the airbag light is on after I install it?
In some cases, the new BCM needs to be synchronized with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional-grade scan tool.
Will this fix my ‘Service 4WD’ message?
While the BCM can cause a wide range of issues, the ‘Service 4WD’ message is more commonly related to the Transfer Case Control Module (TCCM) or the encoder motor. It’s important to diagnose the specific trouble codes before ordering parts.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty BCM back to us, which simplifies your repair process.
