If you’re dealing with baffling electrical issues in your 2010 Cadillac SRX, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a luxury vehicle into a source of daily frustration. The BCM is the central nervous system for your car’s comfort and convenience features—when it goes bad, it can cause a cascade of problems that seem completely unrelated. This isn’t just a part; it’s a solution to restore order to your vehicle’s electronics.
We offer a straightforward and reliable fix. Instead of towing your SRX to a dealership and paying for expensive diagnostics and programming, our service handles the complex part for you. You simply send us your original BCM, and we transfer all the critical vehicle-specific data to this replacement unit. The module you receive back will be plug-and-play, perfectly synced to your vehicle’s VIN and options. It’s the most efficient way to get your car back to 100% functionality without the dealership hassle.
Case Study: A Tricky Diagnosis
A customer brought in a 2010 SRX with a laundry list of complaints: the radio would randomly shut off, the driver-side window wouldn’t go down, and the anti-theft light would flash intermittently, sometimes preventing the car from starting. They had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I found multiple communication loss codes (U-codes) pointing to the BCM. These modules are the traffic cops of the car’s network. When they fail, data gets lost, and systems stop talking to each other. By providing a programmed 2010 SRX Body Control Module, we resolved all the issues in one shot, saving the customer from chasing down individual phantom problems.
Common Signs of a Failing BCM
- ✔️ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔️ Interior or exterior lights (headlights, dome lights) staying on or not turning on.
- ✔️ The security system engaging randomly or preventing the engine from starting.
- ✔️ The horn honking unexpectedly or the panic alarm going off.
- ✔️ Multiple, unrelated warning lights on the dashboard.
- ✔️ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or U0100.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2010 Cadillac SRX, the Body Control Module is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Seat your newly programmed BCM into the mounting bracket and secure it. Reconnect all electrical connectors firmly until they click into place.
- ✔ Power Up and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm proper operation.
Important Post-Installation Information
While our programming service for the 2010 SRX Body Control Module makes this a plug-and-play process, some GM vehicles may require a couple of quick relearn procedures after the new module is installed. These are not always necessary but are good to be aware of:
- Airbag System Sync: If your 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: To ensure your brake lights and traction control system function correctly, a brake pedal position sensor recalibration might be required on some models.
Disclaimer: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions About The 2010 SRX Body Control Module
How does the programming service work?
After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we extract the vehicle-specific data and transfer it to the replacement module. We then ship the programmed module back to you, ready for installation. This process ensures 100% compatibility.
Do I need to do any programming myself?
No. The module you receive from us is fully programmed and ready to be installed. Our service eliminates the need for expensive scan tools or a trip to the dealership for programming.
What if my original part number is slightly different?
This module is compatible with several part numbers, including 13577850, 13505326, and more as listed above. As long as your part number is on our compatibility list, this module will work for your vehicle.
Is there a core charge for my old BCM?
No, there is no core charge. However, we do require your original module to perform the data cloning service. You will not get your original module back.
What causes a BCM to fail?
BCM failure can be caused by several factors, including voltage spikes from jump-starts, water intrusion from a leak, or simple degradation of internal electronic components over time. It’s a common issue in many modern vehicles.
