Restore Order to Your Vehicle’s Electrical System
Are you battling a frustrating array of electrical problems in your Cadillac, Chevy, or GMC? When interior lights flicker, power windows refuse to work, or your dashboard lights up with random warnings, the culprit is often a failing Body Control Module (BCM). This component acts as the central nervous system for your vehicle’s comfort and convenience features. A faulty BCM can make your reliable vehicle feel unpredictable and unsafe. This isn’t just an inconvenience; it’s a breakdown in your car’s core communication network.
We offer a straightforward, reliable solution. This listing is for a replacement BCM that comes fully programmed using the data from your original module. This cloning service ensures that all your vehicle-specific settings, including security information and option configurations, are perfectly preserved. The result is a true plug-and-play replacement for your faulty 2015 Escalade BCM, eliminating the need for expensive and time-consuming dealership programming.
From the Diagnostic Bay
I remember a 2015 Suburban that came into the shop with a list of symptoms that had the owner at his wit’s end. The radio would turn on and off, the driver’s side power window worked intermittently, and the anti-theft light would flash randomly, sometimes preventing the truck from starting. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a slew of ‘Loss of Communication’ codes (U-codes) pointing to the BCM. Instead of a costly new module and hours of programming, we performed a cloning service just like this one. The customer mailed in his old BCM, we transferred the data, and sent the replacement back. He installed it in his driveway in under 30 minutes, and every single electrical gremlin was gone. It’s a repair that provides immense value and relief.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or seats not working correctly.
- ✔ The security system engaging randomly or preventing the engine from starting.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Multiple warning lights on the dashboard with no apparent cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or U0164.
- ✔ Wipers or climate control behaving erratically.
A Straightforward Guide to Installation
Installing your pre-programmed 2015 Escalade BCM is a simple process that most DIYers can handle. Our service makes it a direct swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the BCM: On most compatible models like the Escalade, Tahoe, and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove the bolts or clips holding the module in place.
- Install the Replacement: Mount the new, programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a click as they lock into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, windows, locks, etc.—to confirm the repair. Note the post-installation procedures below, as some recalibrations may be necessary.

Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal.
- Airbag System Sync: If the airbag light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be done with a professional scan tool to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper brake light and stability control function.
- No Core Charge: You do not need to return your old module after the service is complete, as we use it for the initial data transfer. There are no hidden fees.
Disclaimer: Always consult a factory service manual for procedures specific to your vehicle’s year and model.
Frequently Asked Questions
How does the mail-in programming service work?
After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the critical data to the replacement BCM and ship it back to you, usually within 1-2 business days.
Will I need to go to the dealership for programming?
No. Our cloning service completely eliminates the need for dealership intervention. The replacement module will be plug-and-play for your vehicle’s specific configuration.
Is this a guaranteed fix for my vehicle’s electrical problems?
If your vehicle’s symptoms and diagnostic codes point to a faulty BCM, this service provides a reliable and effective solution. It restores the function of the body control systems managed by this module.
What happens if the airbag light comes on after I install it?
This is a known possibility. A repair shop or a technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag module with the new BCM and turn off the light.
Does my original part number have to be 13594768?
No, this module and service are compatible with several interchangeable part numbers, including 13594692, 13593214, 13580690, 13591519, and 13594769.
