Tired of Unpredictable Electrical Problems in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable vehicle into a source of constant frustration. One minute your power windows work, the next they don’t. The security light flashes for no reason, or worse, the vehicle won’t start at all. This isn’t just an annoyance; it’s a breakdown of your vehicle’s central nervous system. This module, part number 22820314, is the direct-fit, reliable solution for your 2013-2017 GMC Acadia and a wide range of other GM vehicles facing these exact issues.
The biggest hurdle with BCM replacement has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our experts will program this BCM with the latest GM software specifically for your vehicle. It arrives at your door ready for installation, saving you time, money, and a major headache.
A Technician’s Notebook: The Ghost in the Traverse
A customer brought in a 2015 Chevy Traverse with a laundry list of bizarre, intermittent complaints: the radio would sometimes stay on after the key was out, the dome lights flickered randomly, and occasionally the engine would crank but not start. They’d been to two other shops that couldn’t find the issue because it never acted up for them. After running a full network scan, I saw multiple U-codes (communication loss) pointing to the BCM. A failing BCM acts like a bad switchboard operator, sending scrambled signals or none at all. We installed a VIN-programmed module just like this one, and every single ghost-like electrical issue vanished. It’s a definitive fix for a complex problem.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these symptoms, a faulty BCM is the likely culprit. Replacing your failing unit with this pre-programmed 2013-2017 Acadia BCM can restore proper function and peace of mind.
- âś” Power windows, door locks, or mirrors working erratically or not at all.
- âś” Horn honking unexpectedly or failing to work when pressed.
- âś” Interior and exterior lights (headlights, brake lights) flickering, staying on, or not turning on.
- âś” Vehicle security system engaging randomly, preventing the car from starting (Security light on).
- âś” Instrument cluster gauges behaving erratically or dashboard warning lights (like ABS or Airbag) illuminating without cause.
- âś” Communication error codes stored, such as U0140, U0155, or U0100.
- âś” A/C and climate control functions not responding correctly.
Your Straightforward BCM Installation Guide
Installing your new BCM is a manageable job for a DIY enthusiast. While the exact location varies (typically behind the lower-left dash on an Acadia), the general steps are consistent. Always consult a service manual for your specific vehicle’s details.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10-15 minutes to allow all systems to power down completely.
- Locate the BCM: On most supported SUVs and cars, you’ll need to remove the lower dash panel on the driver’s side. On vans like the Express or Savana, it’s often located in the center dash area.
- 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 old module and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Secure it with the original hardware.
- Reconnect Everything: Plug all the electrical connectors firmly into the new BCM. You should hear a click as they lock into place. Reconnect the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, horn, and wipers—to ensure everything is working correctly. See the note below regarding potential post-installation procedures.
Important Post-Installation Information
This BCM is programmed to your VIN to ensure maximum compatibility. However, in some cases, additional synchronization may be needed:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is required 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 and traction control operation.
- No Core Charge: You are not required to return your old BCM. There is no core charge or deposit associated with this purchase.

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is critical. We use it to program the BCM with the correct software and vehicle-specific options, ensuring it works correctly right out of the box.
Is this a plug-and-play installation?
For most functions, yes. Because we pre-program it, you avoid the mandatory dealership programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal sensor, which may require a scan tool.
What tools do I need to install this 2013-2017 Acadia BCM?
Basic hand tools are usually all that’s required for the physical installation, such as a socket set and trim removal tools to access the module behind the dash. No special programming tools are needed on your end.
Will this fix my ‘Service StabiliTrak’ message?
It can. A faulty BCM can disrupt communication with the traction control system, causing this warning. If the BCM is the root cause, this part will resolve the message. However, this warning can also be caused by other components like wheel speed sensors.
Is there a core charge?
No. We do not require you to send your old part back. You can keep your original module without any additional fees or deposits.
