Restore Your Cadillac’s Core Functions and End Electrical Frustrations
Are you dealing with bizarre electrical issues in your Cadillac ELR or other GM vehicle? Flickering lights, malfunctioning windows, a dead instrument cluster, or a car that refuses to start can all point to a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. The dealership solution often involves a brand-new module and several hours of expensive programming fees. We offer a smarter, more efficient fix.
This is a comprehensive programming service for a replacement Body Control Module, part number 13593775. Instead of you facing the high costs and complexities of dealership programming, we handle it all. Our process is simple: you purchase this service, ship us your original BCM, and we transfer all the critical data—including your vehicle’s VIN and specific options—to this fully tested replacement unit. The module you receive back will be 100% plug-and-play, ready for installation without any need for a trip to the dealer. This is the most reliable way to get a replacement 2014-2016 ELR BCM that works correctly right out of the box.
From the Diagnostic Bay: The Ghost in the Machine
I once had a 2015 Cadillac SRX in the shop with symptoms that drove the owner crazy. The radio would turn on and off by itself, the security light was always on, and sometimes the power liftgate wouldn’t open. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a flurry of U-codes, specifically a U0140 (Lost Communication With Body Control Module). This told me the BCM wasn’t talking to the other modules correctly. Instead of a costly new unit, we performed a cloning service just like this one. The result? Every single electrical gremlin vanished. It’s a testament to how a targeted BCM fix can solve a host of seemingly unrelated issues.
Is Your Vehicle Showing These Signs of BCM Failure?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security system light stays on, or the alarm goes off randomly.
- ✔ Instrument panel gauges behaving erratically or not working at all.
- ✔ The vehicle won’t start, but the battery and starter are good (a common BCM symptom).
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
- ✔ Wipers or headlights turning on by themselves or not working when commanded.
A Straightforward Guide to Your BCM Installation
Installing your programmed BCM is a manageable task. For the 2014-2016 Cadillac ELR, the BCM is typically located in the right-hand cowl area. Always confirm the location for your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to discharge.
- Locate the BCM: Access the module. In the ELR, this is on the passenger side, near the cowl/firewall area. For other models, it may be under the dash or in a kick panel.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt the module from its mounting bracket and remove it.
- Install the New Module: Mount your newly programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test Functions: Start the vehicle and test all body electronics: windows, locks, lights, radio, and wipers to confirm proper operation.
Important Post-Installation Notes
While our goal is a 100% plug-and-play experience, some modern vehicle systems require a handshake after a new module is introduced. Be aware of the following possibilities:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed. This requires a professional-grade scan tool to sync the BCM with the airbag module and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure perfect brake light and stability control function. This is also performed with a capable diagnostic tool.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
How does the mail-in programming service work?
It’s simple. After you place your order, we will contact you with detailed instructions to ship your original BCM to our facility. Once we receive it, our technicians will clone the data to the replacement module and ship it back to you, typically within 1-2 business days.
Will this module be plug-and-play?
Yes. Because we clone the data from your original unit, the replacement BCM will be programmed with your car’s specific VIN and settings. This eliminates the need for any additional programming upon installation.
Do I need to send my keys?
No, you only need to send the Body Control Module itself. All key and security information is contained within the module’s data, which we will transfer.
Is there a core charge?
No, there is absolutely no core charge for this service. You can keep your original, non-functional module.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module has suffered extreme physical damage (fire, flood, etc.), please contact us before ordering to discuss options.
