Restore Your Vehicle’s Electrical Functions with a Plug-and-Play Solution
Are you dealing with a storm of bizarre electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or an engine that refuses to start for no apparent reason? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can make your car or truck feel haunted. I’ve spent two decades diagnosing these exact issues, and I can tell you that a failing BCM is often the culprit behind these frustrating gremlins.
This isn’t just a replacement part; it’s a direct solution. We take the guesswork and hassle out of the repair by pre-programming this GM Body Control Module to your vehicle’s specific VIN. This means you can skip the expensive trip to the dealership for programming. Simply provide us with your VIN at checkout, and we’ll handle the software side, loading the latest GM updates. You’ll receive a module that’s ready for installation, designed to restore the functions you rely on every day.
Case Study: A Tricky Diagnosis
A customer brought in their 2011 Chevy Traverse last month with a list of complaints that seemed completely unrelated. The dome lights would stay on, the radio would randomly shut off, and occasionally, the vehicle wouldn’t start, despite having a new battery. They were getting communication error codes, specifically U0140 (Lost Communication With Body Control Module). After checking the main power and ground circuits to the BCM, we confirmed the module itself had an internal failure. Swapping in a pre-programmed BCM like this one solved every single issue. The key is that a failing BCM can disrupt the entire vehicle’s communication network, causing a cascade of problems that can be tough to pinpoint without experience.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it might be time for a replacement:
- ✔ Erratic behavior of interior/exterior lights (flickering, staying on, or not working at all).
- ✔ Power windows, locks, or mirrors functioning intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or various B-codes.
A Straightforward Guide to Installation
Replacing your GM Body Control Module is a manageable job for a DIY enthusiast. While locations vary by model (check your service manual), the general process is similar.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: It’s typically found under the dashboard on the driver’s side, behind the glove box, or in the center console area. The fitment list below provides common locations.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Then, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM and securely reconnect all the electrical harnesses.
- Reconnect Battery & Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test your lights, windows, locks, and other body functions to ensure they are working correctly.
Important Post-Installation Steps
After installing your new BCM, a couple of final integration steps are required to ensure full system functionality and safety. These procedures sync the new module with other critical systems in your vehicle.
- Airbag System Reset: To clear the airbag warning light, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level diagnostic scan tool. This is a critical safety step.
- Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position (BPP) sensor to be recalibrated after BCM replacement. This ensures accurate brake light operation and stability control performance.
Note: If you are not equipped to perform these relearn procedures, a qualified automotive technician will be able to complete them for you.

Frequently Asked Questions
Do I need to send my old BCM in?
No core charge or return is required. This is an outright purchase of a replacement GM Body Control Module.
What information do you need to program the module?
We need your vehicle’s 17-digit Vehicle Identification Number (VIN). Please provide it during checkout or send it to us in a message after your purchase to avoid shipping delays.
Is this a simple plug-and-play installation?
The module is programmed to be plug-and-play for most basic functions. However, as noted above, critical safety systems like the airbag (SRS) and sometimes the brake pedal position sensor will require a relearn procedure with a professional scan tool after installation.
Will this fix my specific problem?
This module will resolve issues directly caused by a faulty BCM. While the symptoms we’ve listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
What if my part number isn’t 15299986 but is on the list?
That’s perfectly fine. GM often updates part numbers over time. All the part numbers listed in the description are interchangeable, and this module serves as a direct, updated replacement for all of them.
