Restore Full Functionality to Your GM Vehicle with a Pre-Programmed BCM
Are you battling a storm of bizarre electrical issues in your truck or SUV? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or even a frustrating no-start condition can all point to a single culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can turn your reliable ride into a source of constant headaches. This is where our professional cloning service for the 2015 Sierra Denali 2500 BCM comes in, offering a direct and dependable fix.
Instead of facing expensive dealership programming and lengthy vehicle downtime, our service simplifies the entire process. You simply send us your original BCM. Our expert technicians will then transfer all the critical, vehicle-specific data—including VIN, mileage, and key information—to this fully tested replacement module. We ship it back to you ready for installation, creating a true plug-and-play solution that gets you back on the road without the need for a trip to the dealer. This service covers part number 13594769 and other compatible numbers listed below.
A Technician’s Notebook: The Case of the Haunted Sierra
“A 2015 Sierra 2500 rolled into my bay last month with a list of complaints that sounded like a ghost was in the machine. The dome lights would pulse randomly, the radio would shut off, and the driver’s side window wouldn’t go down. The owner had already replaced the battery and checked all the fuses. A scan showed a slew of U-codes, specifically U0140 (Lost Communication With Body Control Module). After verifying the network wiring was intact, we identified the BCM as the source of the data corruption. A cloned BCM like this one solved every single issue in under an hour of shop time after the part arrived. It’s often the central point of failure for these widespread, unrelated electrical problems.”
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a failing BCM is the likely cause. This service for the 2015 Sierra Denali 2500 BCM is designed to correct these exact problems.
- ✔ Intermittent or non-functional power windows, door locks, and mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Instrument cluster warning lights appearing for no reason (e.g., security light, airbag light).
- ✔ Problems with the keyless entry or remote start systems.
- ✔ A vehicle that cranks but refuses to start due to security system lock-out.
- ✔ Communication Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or B1001.
A Straightforward Guide to Installation
Our cloning service makes the final installation step incredibly simple. Here is a general guide to get your vehicle running properly again:
- Step 1: Send Us Your Original Module. After purchase, we will contact you with simple instructions for shipping your original BCM to our facility. Ensure your contact information is correct at checkout.
- Step 2: We Clone Your Data. Once we receive your module, our technicians will perform a full data transfer to the replacement BCM. We then ship the newly programmed module back to you, typically within 24-48 hours.
- Step 3: Disconnect the Battery. Before starting the physical installation, always disconnect the negative terminal of your vehicle’s battery to prevent any electrical shorts.
- Step 4: Locate and Replace the BCM. On most GM trucks and SUVs like the Sierra, the BCM is located under the steering column on the driver’s side. Carefully disconnect the wiring harnesses, unbolt the old module, and install the new one 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 vehicle and test all body functions—lights, windows, locks, etc.
- Step 6: Perform Relearns if Necessary. In some cases, you may see an airbag light or have brake system messages. Follow the post-installation procedures outlined below if these occur.
Important Post-Installation Notes
While our goal is a seamless experience, some modern vehicles require a final handshake between modules. Be aware of these potential, easy-to-resolve steps:
- 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 airbag system with the new BCM and is a common requirement.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation. This also requires a capable diagnostic tool.
- No Core Charge: You are not required to send your old part back after the service is complete. There is no core charge or fee.
