Restore Full Functionality to Your Luxury SUV
Are you battling frustrating and unpredictable electrical problems in your 2015 Cadillac Escalade ESV? Issues like flickering lights, malfunctioning power windows, a temperamental security system, or even a no-start condition can often be traced back to a single component: the Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, a failing BCM can cause widespread chaos. Dealerships often quote exorbitant prices for a new module plus mandatory programming fees. We offer a reliable and cost-effective solution. This is a replacement BCM, part number 13594769, that comes pre-programmed with your vehicle’s exact data.
Our professional cloning service makes this a truly plug-and-play repair. Simply purchase this module, and we’ll provide instructions for shipping your original BCM to our facility. Our technicians will then transfer all the critical information—including VIN, mileage, and key programming—to this replacement unit. We ship it back to you, ready for installation without any need for expensive dealer tools. This process ensures a seamless integration with your vehicle’s existing systems, getting you back on the road quickly and confidently.
Case Study: A Tricky Diagnosis
A few months back, a 2015 Suburban (which shares its platform with the Escalade) came into my shop with a laundry list of bizarre symptoms. The owner reported that the radio would sometimes stay on after he left the truck, the power locks worked intermittently, and the instrument cluster would occasionally go dark while driving. Initial scans showed a dozen communication error codes (U-codes), pointing fingers everywhere. After verifying the main power and ground circuits to the BCM were solid, we knew where the problem was. These modules are notorious for internal solder joint failures. We performed our cloning service onto a replacement BCM, and within an hour of installation, every single electrical gremlin was gone. This is a classic failure mode for this 2015 Escalade ESV BCM and its cousins.
Is Your Cadillac Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic instrument cluster behavior or warning lights that come on for no reason.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Communication error codes, such as U0140, U0155, or other U-codes pointing to a loss of communication with various modules.
- ✔ Problems with the keyless entry and push-to-start systems.
Your Straightforward BCM Installation Guide
Once you receive your pre-programmed BCM from us, the physical installation is very manageable for a DIYer. The module is typically located under the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the BCM: On the 2015 Escalade ESV, the BCM is found under the steering column, often behind a lower dash panel. You may need to remove a plastic trim piece for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the Replacement: Mount the new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Test Functions: Start the vehicle and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair was successful.
Important Post-Installation Note: In some cases, additional steps may be required. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary. There is no core charge for this part; you can keep your original module.

Frequently Asked Questions
Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. We then clone the data from your module to the replacement unit and ship it back to you, typically within one business day of receiving yours.
Is this a plug-and-play solution?
Yes. Because we clone your vehicle’s original data, the replacement BCM is ready for installation without any additional programming or trips to the dealership.
Do I need to send my keys?
No, you only need to send us your original Body Control Module. All key information is stored within the BCM and will be transferred during the cloning process.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be synced with the airbag module (SDM). A repair shop with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is there a core charge?
No, there is no core charge. You are free to keep your original module after the service is complete.
Will this fix my specific problem?
This part resolves issues directly caused by a failing BCM. It’s crucial to have a proper diagnosis to confirm the BCM is the source of your problems before ordering, as this is the best way to ensure a successful repair of your 2015 Escalade ESV BCM.
