Is Your GMC Terrain Experiencing Strange Electrical Issues?
If your 2010-2011 GMC Terrain, Chevy Equinox, or other compatible GM vehicle is acting possessed, you’re not alone. Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or even a vehicle that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. Replacing it at the dealership often means expensive parts, programming fees, and significant downtime. But there’s a better way.
This listing is for a replacement Body Control Module, part number 13577850, that comes pre-programmed with your vehicle’s original data. This is not just a part; it’s a complete, hassle-free solution. By using our simple mail-in cloning service, we transfer the vital information—including key data, security settings, and specific vehicle options—from your original BCM to this replacement unit. The result is a true plug-and-play module that restores full functionality without any need for a trip to the dealer for costly programming.
Common Symptoms of a Failing 2010-2011 Terrain BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely cause:
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security system light stays on, or the alarm goes off randomly.
- ✔ Dashboard warning lights (like the airbag or brake light) illuminate for no reason.
- ✔ The radio or infotainment system behaves erratically or won’t turn on.
- ✔ Remote keyless entry fails to work consistently.
- ✔ The vehicle won’t start, and you hear a rapid clicking sound, even with a good battery.
- ✔ Turn signals or hazard lights work intermittently or not at all.

Installation and Post-Install Procedures
The BCM is typically located on the driver’s side, behind the lower dash or kick panel. Once you receive the programmed module, installation is straightforward. Simply disconnect the battery, remove the old BCM, install the replacement, and reconnect the battery. While our programming makes this a plug-and-play process, some vehicles may require minor recalibration procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control function.
Please consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and other comfort and convenience features.
