GM Body Control Module 15828601 | Pre-Programmed with Your VIN

Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM

If you’re dealing with bizarre electrical issues in your GM vehicle—like power windows with a mind of their own, dashboard lights flickering like a disco, or a security system that randomly prevents you from starting your car—you’ve likely met the culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating guessing game. This isn’t just an annoyance; it can be a significant safety and reliability concern.

This is a direct-fit replacement Body Control Module, compatible with a wide range of GM vehicles and part numbers including 15828601. The biggest hurdle in replacing a BCM has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. By providing us with your vehicle’s VIN at checkout, our technicians will pre-program this module with the latest GM software specific to your car or truck. It arrives at your door ready for installation, saving you hundreds in dealer fees and diagnostic time.

Is Your GM Vehicle Showing These Symptoms?

A failing BCM doesn’t always trigger a check engine light. Instead, it manifests as a series of strange electrical failures. Here are the most common signs I’ve seen in my 20+ years of diagnostics:

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior or exterior lights that won’t turn on or off.
• ✔ The security or anti-theft system preventing the engine from starting.
• ✔ Dashboard warning lights (like ABS or Airbag) illuminating for no reason.
• ✔ Horn sounding unexpectedly or not working at all.
• ✔ Intermittent wiper operation or wipers that won’t park correctly.
• ✔ Communication error codes, such as U0140, U0155, or other “U” codes, stored in various modules.

Your Step-by-Step BCM Installation Guide

Replacing the BCM is a manageable job for a DIYer with basic tools. The location varies by model (see fitment list), but it’s typically under the dash. Always consult a service manual for your specific vehicle.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10-15 minutes to allow all modules to power down completely.
2. Locate the BCM: Find the old BCM. It’s often located on the driver’s or passenger’s side, under the dashboard, or behind a kick panel.
3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
4. Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all the electrical harnesses. You should hear a click as they lock into place.
5. Reconnect Power: Re-attach the negative battery terminal.
6. Perform Relearns (If Needed): Start the vehicle. In some cases, you may need to perform a post-installation procedure, like a Brake Pedal Position Relearn or an Airbag System Sync, if related warning lights appear.

Important Post-Installation Information

Because this Programmed GM Body Control Module is flashed to your VIN, it integrates seamlessly in most cases. However, depending on your vehicle’s specific configuration, some additional sync procedures may be required. This is a normal part of the process when replacing a central computer.

• No Core Charge: You are not required to return your old BCM. There is no core fee.
• Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure correct operation of the brake lights and stability control systems.
• Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.
