Restore Full Functionality to Your GM Vehicle
Are you battling bizarre electrical issues in your Cadillac, GMC, or Chevrolet truck or SUV? One moment the power windows refuse to work, the next the radio is acting up, and then the security light starts flashing for no reason. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. This replacement BCM, part number 22846365, is the direct-fit, reliable solution to restore order and get your vehicle operating as it should.
From the Diagnostic Bay: The Escalade with a Mind of Its Own
I remember a 2013 Escalade ESV that came into my shop with a list of complaints that seemed completely unrelated. The owner said the remote start would sometimes fail, the driver’s side power seat had stopped working, and the instrument cluster would flicker intermittently. He had already replaced the battery, thinking it was a simple power issue. After connecting my scan tool, I found a slew of communication errors (U-codes) pointing to a network problem. In my 20+ years of experience, when you see a mix of seemingly random body electronic failures like this, the BCM is the prime suspect. We installed a VIN-programmed BCM, and instantly, every single issue was resolved. It’s the ‘brain’ of the body, and when it goes, the symptoms can be chaotic.
Is Your GM Truck or SUV Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your Body Control Module is the culprit. Replacing it with this pre-programmed unit can solve these issues in one go.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, dome lights) staying on or not turning on.
- ✔ The anti-theft or security system light is on, preventing the vehicle from starting.
- ✔ The instrument cluster gauges or warning lights behave strangely.
- ✔ Remote keyless entry (RKE) is unresponsive.
- ✔ Communication Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes, are present.
A Straightforward Guide to Installation
This replacement is designed to be as simple as possible, thanks to our pre-programming service. The BCM is typically located under the driver’s side dashboard. While specific steps can vary slightly, here is a general guide for your 2012-2014 Escalade ESV BCM replacement.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work on any electronic component.
- Access the Module: Remove the lower dash panel or knee bolster beneath the steering column to gain access to the BCM. It’s often mounted to a bracket with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting location.
- Install the New BCM: Mount your new, pre-programmed BCM in the exact same position as the old one. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect and Test: Reinstall the dash panel, reconnect the negative battery terminal, and start the vehicle. Test all functions like windows, locks, lights, and radio to confirm the repair.
Important Post-Installation Information
While our programming handles the majority of the setup, 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 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 recalibration might be required to ensure proper brake light and traction control operation.
- No Core Charge: You are not required to send your old BCM back to us. There is no core charge or deposit associated with this purchase.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Does this BCM need to be programmed by a dealer?
No. We flash the module with the latest GM software using the VIN you provide during checkout. It arrives ready to install, saving you a trip to the dealership and costly programming fees.
Where is the BCM located on my 2013 Escalade?
The Body Control Module (BCM) on most compatible models, including the 2012-2014 Escalade ESV, is located under the driver’s side of the dashboard, near the steering column.
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit identification number. We use it to load the exact software and settings your specific vehicle requires, ensuring perfect compatibility with its options and features.
Do I have to return my old BCM?
No. This product comes with absolutely no core charge. You can keep or dispose of your original module.
What if my airbag light is on after I install it?
This is a possibility. It means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a professional-grade scan tool to complete the system sync.
