Restore Full Functionality to Your Cadillac
Are you experiencing a cascade of bizarre electrical issues in your 2013 Cadillac XTS? From flickering interior lights and malfunctioning power windows to a car that refuses to start, a failing Body Control Module (BCM) can turn your luxury vehicle into a source of constant frustration. The BCM is the central nervous system for your car’s body electronics, managing everything from the security system and keyless entry to the lighting and climate controls. When it fails, the symptoms can be widespread and difficult to diagnose. This is the definitive solution to restore your vehicle’s electronic stability and performance.
The Simple, No-Hassle Solution: Our Programming Service
Replacing a modern BCM isn’t as simple as swapping parts. The module is coded specifically to your vehicle’s VIN, security information, and equipped options. A new or used module from another vehicle will not work without extensive, dealer-level programming. Our unique service eliminates this costly and time-consuming step. Here’s how it works:
- Place Your Order: Complete your purchase for this BCM.
- Ship Us Your Original BCM: We will contact you with simple shipping instructions to send your original, faulty BCM to our facility. Please ensure your contact information is correct at checkout.
- We Transfer the Data: Our expert technicians will professionally transfer all the critical data from your original module to this replacement unit. This includes your VIN, key information, and vehicle-specific settings.
- Receive a Plug-and-Play Module: We ship the newly programmed module back to you. Once you receive it, installation is straightforward. Simply disconnect the battery, remove the old BCM, install the new one, and reconnect the battery. No further programming is required.
Common Symptoms of a Failing 2013 Cadillac XTS BCM
- ✔ Intermittent or complete failure of power windows, door locks, or mirrors.
- ✔ Interior or exterior lights behaving erratically (flickering, staying on, or not turning on).
- ✔ The anti-theft or security system light is illuminated or flashing, preventing the car from starting.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Key fobs not being recognized or functioning inconsistently.
- ✔ Climate control system not responding to commands.
- ✔ Communication errors with diagnostic scan tools (U-codes).
Post-Installation Procedures
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a recalibration or sync procedure after the BCM is replaced. These are simple procedures for a qualified technician with a professional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, the ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only required if the light appears.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be necessary to ensure correct brake light operation and traction control performance.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that acts as the central command for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls, ensuring they all work together seamlessly.
Why do I need to send you my original module?
Your original module contains unique security and configuration data specific to your car’s VIN. By transferring this data to the replacement module, we make it a true plug-and-play part, saving you from needing expensive and complex programming at a dealership.
Is this BCM ready to install when I get it back?
Yes! Once we program the module with your vehicle’s data, it is ready for installation. In most cases, no additional steps are needed. However, as noted, some vehicles may require a simple sync procedure for the airbag or brake systems if a warning light appears.
What if my original BCM is completely dead or ‘fried’?
Even if your module is non-functional, our technicians can often still extract the necessary data from the memory chip. Please contact us before ordering if your module has significant water or fire damage.
Do I need to return my old BCM after I receive the programmed one?
No, there is no core charge for this item. You have already sent us your original module for the programming service, so you are all set. You can keep your original module.
