Restore Full Functionality to Your Cadillac SRX
If you’re dealing with bizarre electrical issues in your 2014-2016 Cadillac SRX—like power windows with a mind of their own, intermittent starting problems, or dashboard warning lights that won’t go away—a failing Body Control Module (BCM) is often the culprit. As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can cause immense frustration. This isn’t just an inconvenience; it can affect vehicle security and safety systems. We offer a straightforward, reliable solution that gets you back on the road without the exorbitant costs and scheduling headaches of a dealership visit.
Our service provides you with a fully functional replacement BCM, precisely programmed with your vehicle’s original data. This is achieved through a simple mail-in cloning process. You send us your original module, and our expert technicians transfer all the critical information—including VIN, mileage, and key data—to this replacement unit. The result? A true plug-and-play module that restores your vehicle’s electronics to perfect working order.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security system preventing the vehicle from starting, even with the correct key.
- ✔ Inconsistent or non-functional instrument cluster gauges and warning lights.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module), stored in the system.
- ✔ Headlights, taillights, or turn signals not working correctly.
- ✔ Remote keyless entry failure.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 SRX with a classic BCM failure story. The radio would turn on by itself, the driver’s side window wouldn’t go down, and the key fob worked only half the time. They had already replaced the battery and checked fuses, but the gremlins persisted. After plugging in my scanner, I saw a dozen communication codes pointing back to the BCM. These modules are the traffic cops for dozens of electronic signals. When they fail internally, it causes chaos. By providing a cloned 2014-2016 SRX Body Control Module, we had the vehicle’s functions fully restored in an afternoon, saving the customer hundreds compared to the dealer quote.
A Straightforward Guide to Installation
- ✔ Safety First: Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2014-2016 Cadillac SRX, the Body Control Module is typically located behind the left-hand (driver’s side) of the dashboard. Access may require removing lower dash panels.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the original BCM. Note their orientation. Then, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount your newly programmed BCM in the same location and securely re-fasten it. Reconnect all electrical connectors, ensuring they click into place.
- ✔ Reconnect Battery: Re-attach the negative battery terminal.
- ✔ Test All Functions: Start the vehicle and thoroughly test all body-related functions: windows, locks, lights, wipers, radio, and key fobs to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM vehicles may require simple recalibration procedures after a BCM replacement. These are typically only necessary if a specific warning light appears:
- Airbag System Sync: If the airbag warning light is on 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 needed to ensure proper brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions
How does the mail-in programming service work?
After you place your order, we will contact you with simple instructions and a shipping address. You’ll send us your original BCM. Once we receive it, we transfer the data to the replacement unit and ship it back to you, typically within 1-2 business days.
Is this a plug-and-play part?
Yes. Because we clone the data from your original module, this part is 100% plug-and-play. No additional programming or trips to the dealer are required for it to function.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which we will transfer during the cloning process.
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. Please contact us before ordering if your module is severely damaged by fire or water, or if a technician has confirmed it has no communication.
Is there a core charge for my old part?
No, there is no core charge. We require your original module for the cloning service, but you can keep it after the service is complete if you wish.
