Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your GMC Terrain or other compatible GM vehicle? Intermittent power windows, flickering dash lights, a security system that acts up, or a vehicle that refuses to start can often be traced back to a single culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM falters, it can cause a cascade of confusing and unpredictable problems. This isn’t just an inconvenience; it can affect vehicle safety and reliability.
This listing is for a professionally programmed Body Control Module, a direct replacement for part number 13504004 and other interchangeable numbers listed below. We take the guesswork and high dealership costs out of the equation. By using our simple mail-in cloning service, you receive a module that is 100% plug-and-play. We transfer the critical data from your original BCM to this replacement unit, ensuring it communicates perfectly with your vehicle’s existing components right out of the box. This means no expensive trips to the dealer for programming.
A Technician’s Notebook: The Case of the Haunted Terrain
A customer brought in a 2011 GMC Terrain with a list of symptoms that sounded like something out of a ghost story. The radio would turn on and off by itself, the door locks would cycle while driving, and occasionally, the vehicle wouldn’t start, leaving the driver stranded. They had already replaced the battery to no avail. My initial scan pulled several communication codes (U-codes), pointing towards a network issue. In my 20+ years in the bay, this pattern almost always points to the BCM. After confirming power and grounds to the module were solid, we identified the internal BCM failure. Instead of a costly new module and hours of programming at the dealer, we used a cloned unit like this one. The result? A 30-minute swap in our shop, and every single electrical issue was resolved. The customer was back on the road the same day, saving hundreds of dollars.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution for your 2010-2011 Terrain BCM issues:
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ Dashboard warning lights illuminate for no reason (e.g., ABS, Traction Control).
- ✔ Radio or infotainment system malfunctions or won’t turn on.
- ✔ Communication Diagnostic Trouble Codes (DTCs) are present, such as U0100, U0140, U0155.
- ✔ Inconsistent or non-functional remote keyless entry.
A Straightforward Guide to Installation
Our cloning service makes installing your replacement 2010-2011 Terrain BCM a simple process that a confident DIYer or any professional mechanic can perform.
- Purchase & Ship: After you place your order, we will contact you with instructions for shipping your original BCM to our facility. Please ensure your contact information is correct at checkout.
- Cloning Process: Once we receive your module, our technicians will professionally transfer all necessary vehicle data to the replacement unit. We typically ship the programmed module back to you within 24-48 hours.
- Safety First: Before starting the installation, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most 2010-2011 GMC Terrains, the BCM is located on the left (driver’s) side of the dash or in the kick panel area. Consult a service manual for the exact location on your specific vehicle.
- Swap the Modules: Carefully disconnect the wiring harnesses from your old BCM. Remove any mounting bolts or clips and take out the old module. Install the new, programmed module in its place, securing it and reconnecting all wiring harnesses firmly.
- Reconnect & Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair was successful.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential 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 airbag system with the new BCM and is only required if the light is illuminated.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure brake lights and traction control function correctly.
- No Core Charge: You are not required to send your old part back to us after the service is complete. There is no core charge.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified automotive technician for specific guidance related to your vehicle.

What is this cloning service and why do I need it?
What is this cloning service and why do I need it?
Cloning is the process of transferring your vehicle’s specific configuration, security, and key data from your original BCM to our replacement unit. This makes the new module plug-and-play, avoiding the need for expensive and complex programming at a dealership, which is required for a brand new module.
How long does the programming service take?
Once we receive your original module, our technicians typically complete the programming and ship your replacement BCM back to you within one to two business days. We will send you tracking information as soon as it ships.
Is this a guaranteed fix for my vehicle’s problems?
This module will fix problems directly caused by a faulty BCM. While the symptoms we’ve listed are common indicators of BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before purchasing.
Do I need special tools to install this?
For the physical installation, you will only need basic hand tools like a socket set and screwdrivers to access and swap the module. No programming tools are needed. However, in some cases, a professional scan tool might be required for post-installation procedures like an airbag system sync.
What if my original BCM is completely dead or missing?
Our cloning service requires a readable original module to extract the necessary data. If your BCM is water damaged, burnt, or otherwise unreadable, please contact us before purchasing to discuss potential alternative solutions.
