End the Electrical Gremlins in Your GM Van or SUV
Is your Savana, Express, or other GM vehicle acting possessed? Flickering dash lights, power windows with a mind of their own, or a security system that randomly prevents you from starting the engine are all classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s electronics, a faulty BCM can turn a reliable workhorse into a source of constant frustration. In my 20+ years of diagnostics, I’ve seen how these issues can disrupt a workday and lead to costly, incorrect diagnoses. This isn’t just an annoyance; it’s a reliability problem that needs a solid fix.
This is your direct-fit, permanent solution. We offer a replacement Body Control Module, part number 22820314 (also fits 22915542), that arrives at your door fully programmed to your vehicle’s specific VIN. We load it with the latest GM software, ensuring all functions operate exactly as the factory intended. You get to skip the expensive dealership visit for programming, saving you both time and money. This is the straightforward, professional-grade fix you’ve been looking for.
A Technician’s Notebook: The Intermittent No-Start
A local contractor brought in his 2016 Savana 3500. The van would intermittently refuse to start, but only on hot days. The security light would flash, and he’d be stranded for 10-15 minutes. He’d already replaced the battery and ignition switch with no luck. After connecting my scan tool, I found several ‘Lost Communication with BCM’ codes (U0140). Instead of a complex wiring issue, the BCM itself was failing internally when it got hot. A pre-programmed 2013-2019 Savana 3500 BCM like this one was the perfect fix. We swapped it in the bay in under 30 minutes, and he was back on the road for good—no more delays getting to the job site.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ False warnings appearing on the instrument cluster (e.g., ‘Service StabiliTrak’).
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes.
- ✔ Inconsistent horn or wiper operation.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On most Savana and Express vans, the BCM is located in the center dash area, often accessible by removing lower dash panels. For other models like the Acadia or Traverse, it’s typically on the driver’s side behind the lower dash.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting) and test all body functions—lights, locks, windows, etc.—to confirm proper operation.
Important Post-Installation Information
While this module is designed for a simple installation, some vehicle systems may require a quick sync-up procedure. This is normal. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated 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 relearn may be required to ensure your brake lights and traction control system function correctly.
- 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 need to get this BCM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. It arrives ready to install, saving you hundreds in dealership fees.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information for programming.
Where is the BCM located on a 2015 Savana 3500 Van?
On the 2013-2018 Savana and Express vans, the Body Control Module is typically located in the center dash area, accessible from below or by removing trim panels.
What if my airbag light turns on after I install it?
This is not a defect. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
Is there a core charge for this part?
No, there is absolutely no core charge. You can keep your original module without any extra fees or hassle.
