Restore Full Functionality to Your Vehicle with a Pre-Programmed BCM
Are you battling frustrating electrical issues in your Cadillac, Chevy, or GMC? Flickering lights, unresponsive power windows, a security system that acts up, or strange warning messages on the dash are often signs of a failing Body Control Module (BCM). This component is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing problems. Instead of facing a costly trip to the dealership for a new module and expensive programming, our plug-and-play solution gets you back on the road quickly and affordably.
This listing is for a replacement BCM, compatible with part numbers like 13594692 and 13580690, that is professionally programmed with your vehicle’s specific data. The process is simple: after your purchase, you’ll ship your original BCM to us. We will then transfer all the critical information—including VIN, mileage, and security settings—to this replacement unit. The result is a module that is ready to install right out of the box, with no additional programming required. This is the most reliable way to solve your BCM issues without disrupting your vehicle’s complex electronic ecosystem.
Case Study: A Tricky Diagnosis
I recently had a 2015 Cadillac Escalade ESV in the shop with a laundry list of bizarre symptoms. The owner reported intermittent radio failure, the dome lights wouldn’t turn off, and the “Service Airbag” message would pop up randomly. Initial scans showed a dozen communication loss codes (U-codes) pointing to multiple modules. This is a classic BCM failure pattern. The BCM acts as a gateway, and when it starts to fail, it can’t properly route messages on the CAN bus network, making it look like other modules are offline. By swapping in a cloned 2015 Escalade ESV BCM, all communication was restored, and every symptom vanished. This saved the customer over $700 compared to the dealership’s quote.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights staying on or not turning on.
- ✔ The security system light is on, or the alarm goes off randomly.
- ✔ Key fob not being recognized, leading to a no-start condition.
- ✔ Communication error codes, such as U0140, U0155, or other U-codes, stored in the system.
- ✔ Erratic behavior from the instrument cluster or climate controls.
A Straightforward Guide to Installation
Installing your pre-programmed BCM is a manageable job for a DIY enthusiast or any professional mechanic. While the exact location varies, it’s typically found in the driver’s side footwell area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most trucks and SUVs like the Escalade, Tahoe, and Sierra, the BCM is located under the steering column, often behind a plastic trim panel. On sedans like the CTS or Impala, it may be in the LH dash area or on the firewall.
- 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 module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting the engine) and test all body functions: lights, locks, windows, radio, etc.
Important Post-Installation Notes
In some cases, minor follow-up procedures may be needed:
- Airbag System Sync: If the airbag warning light is illuminated 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: Certain models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.

Frequently Asked Questions
Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the unique data and transfer it to the replacement module. We then ship the plug-and-play replacement back to you, typically within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is causing major issues, the core data on the memory chip is still readable. We are successful in recovering data from over 98% of modules we receive. If for some reason the data is not recoverable, we will contact you to discuss options.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. Because we are cloning your original module’s information, the replacement BCM will recognize your existing keys just like the original did.
Is this a guaranteed fix for my vehicle’s problems?
This service corrects issues directly caused by a faulty BCM. While the symptoms listed are strong indicators, proper vehicle diagnosis is essential. We guarantee our programming service and the functionality of the module we provide. Ensure your vehicle has been diagnosed correctly before ordering.
Why is this a better option than going to the dealer?
Our service saves you significant money on both the part and the labor-intensive programming fees charged by dealerships. It’s also a direct-to-your-door solution that doesn’t require towing your vehicle or leaving it at a service center for days.
