Restore Full Functionality to Your GM Vehicle with a Pre-Programmed BCM
Are you battling a storm of bizarre electrical issues in your 2012 Cadillac SRX or other GM vehicle? Flickering lights, a dead instrument cluster, power windows with a mind of their own, or a car that refuses to start can often be traced back to one single component: a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen firsthand how a faulty BCM can turn a reliable vehicle into a source of constant frustration. This isn’t just an inconvenience; it can affect vehicle security and safety systems. You need a reliable, straightforward fix that doesn’t involve exorbitant dealership fees and lengthy programming sessions.
This is your solution. We offer a professionally programmed Body Control Module, ready for installation. Our service is designed to be simple: you send us your original BCM, we transfer all the critical vehicle-specific data (like VIN, mileage, and key information) to this replacement unit, and ship it right back to you. This cloning process makes the replacement a true plug-and-play part, eliminating the need for expensive dealer-only tools. This service covers part number 13583542 and is a direct replacement for several other part numbers, including 13580696, 123589093, 13588446, and 13584692.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ The security system acting up, causing alarm issues or no-start conditions.
- ✔ The remote keyless entry (fob) failing to work.
- ✔ False warning lights appearing on the instrument cluster.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other U-codes indicating a loss of communication with other modules.
From the Diagnostic Bay: The BCM Masquerade
I remember a 2012 GMC Terrain that came into the shop with a classic “no-crank, no-start” condition. The owner had already replaced the battery and the starter, with no luck. The vehicle’s security light was flashing. A quick scan showed a dozen communication codes. The initial thought was a bad network wire or a faulty ECM. However, after tracing the communication lines, I noticed the BCM wasn’t responding correctly. It’s the central hub for security and power distribution. We swapped in a known-good BCM, and the vehicle fired right up. This is a common scenario—a failing BCM often mimics other component failures, leading to wasted time and money on incorrect parts. Our cloning service ensures you’re replacing the right part with one that’s ready to work instantly.
Your Straightforward Installation Guide
- ✔ Step 1: Purchase and Ship. After you place your order, we will provide you with detailed instructions and a shipping address. Please ensure your contact information is up to date. Carefully package and ship your original BCM to us.
- ✔ Step 2: Expert Programming. Once we receive your module, our technicians will perform a full data transfer to the replacement unit. This ensures all your vehicle’s unique settings are preserved. We typically complete this process and ship the programmed module back to you within 24-48 hours.
- ✔ Step 3: Disconnect Power. Before starting the installation, always disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts.
- ✔ Step 4: Locate and Replace. The BCM location varies by model (e.g., left-hand dash in the SRX, right-hand dash in the Camaro). Locate your old BCM, carefully disconnect the wiring harnesses, unbolt it, and install the new programmed module in its place.
- ✔ Step 5: Reconnect and Test. Reconnect the wiring harnesses to the new BCM and then reconnect the vehicle’s battery. Start the car and test all functions—lights, windows, locks, and remote start—to confirm the repair.
Important Post-Installation Notes
In some cases, additional synchronization procedures may be required after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: For certain models, a brake pedal position sensor relearn might be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified automotive technician if you are unsure about any step.

How does the programming service work?
How does the programming service work?
After you complete your purchase, we will contact you with instructions to ship your original BCM to our facility. We then extract the vehicle-specific data from your module and flash it onto the replacement unit. This ‘cloning’ process makes the new module plug-and-play, saving you a trip to the dealer.
Do I need to pay a core charge?
No. There is no core charge for this service. You are free to keep your original module after we have completed the programming service.
Is this part number 13583542 compatible with 13580696?
Yes. Part number 13580696 is a fully compatible, interchangeable replacement for 13583542 and other part numbers listed in the description. We guarantee compatibility for the vehicles listed.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), please contact us before purchasing to discuss options. We may be able to retrieve data from another module in the vehicle.
Will I need a scan tool after installation?
Typically, no special tools are needed. However, as noted, some vehicles may require a ‘Brake Pedal Position Relearn’ or an ‘Airbag System Sync’ if specific warning lights appear after installation. These procedures require a professional-grade diagnostic tool.
