Are you battling bizarre electrical issues in your Chevrolet Equinox or GMC Terrain? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or a vehicle that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and security features, a faulty BCM can create a cascade of frustrating and hard-to-diagnose problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and reliability.
We offer a straightforward and reliable solution. This is a replacement BCM, part number 13586273, that comes ready for installation through our professional cloning service. Instead of buying a blank module and paying for expensive dealership programming, you simply send us your original BCM. We transfer all the essential vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result? A true plug-and-play Equinox Body Control Module that restores full functionality without any extra steps or hidden fees.
Case Study: The Phantom Battery Drain
A 2016 Equinox came into my bay with a classic complaint: a dead battery every morning. The owner had already replaced the battery and alternator, but the problem persisted. Standard parasitic draw tests were inconclusive at first. The draw would appear and disappear randomly. After hours of tracing circuits, I noticed the interior dome light would faintly glow long after the doors were shut. This led me to the BCM. By monitoring the communication network, I confirmed the Equinox Body Control Module wasn’t entering its ‘sleep mode’ correctly, keeping other systems awake and draining the battery. A cloned BCM from our stock solved the issue permanently, saving the customer from further guesswork and expensive part swapping.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Horn honking randomly or the alarm sounding without reason.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module), stored in other modules.
- ✔ A persistent parasitic battery drain that can’t be traced to other components.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2013-2017 Equinox and Terrain, the BCM is typically found on the left (driver’s) side of the dashboard, often behind the lower dash panel or kick panel. Consult a service manual for the exact location on other compatible models.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position and test all body functions—lights, locks, windows, radio, etc.—to confirm proper operation.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure for full system harmony. Please be aware of the following:
- Airbag System Sync: If your 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: To ensure proper brake light and stability control function, a brake pedal position sensor recalibration may be necessary on some models.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified technician if you are unsure about any step.

Frequently Asked Questions
Equinox Body Control Module
Will this fix my car’s no-start problem?
If the no-start is caused by the BCM’s control over the anti-theft system (a common failure), then yes, this programmed is the correct solution.
