Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you dealing with baffling electrical issues in your truck? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own? These are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can turn your reliable workhorse into a source of constant frustration. This isn’t just an annoyance; it can be a safety concern when essential components like lights and door locks become unpredictable.
This listing is for a replacement BCM, part number 13594692, that is delivered to you fully programmed and ready for installation. We take the guesswork and high dealership costs out of the equation with our simple mail-in cloning service. Simply purchase this module, and we’ll contact you with instructions to ship your original BCM to our facility. Our expert technicians will then transfer all the critical vehicle-specific data to this replacement unit. The result? A module that is 100% plug-and-play, with no need for an expensive trip to the dealer for programming.
A Technician’s Notebook
I remember a 2015 Sierra 2500 that came into the bay with a laundry list of intermittent complaints. The radio would shut off, the dome light would stay on, and the driver’s window would only work occasionally. The owner had already replaced the battery and checked the main grounds. Diagnostic codes were all over the place—mostly U-codes pointing to a loss of communication. Instead of just swapping parts, I located the BCM under the steering column. Just by wiggling the main connectors, I could replicate every single issue. This confirmed a failure inside the module itself, not a wiring problem. Our cloning service provided the owner with a reliable fix that got him back on the road without the multi-hundred-dollar programming fee the dealership quoted.
Is Your Truck Showing These Electrical Gremlins?
A failing BCM doesn’t always trigger a check engine light. Instead, it creates a host of strange symptoms that can be difficult to diagnose. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Power windows, locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The vehicle’s security system engaging randomly or preventing the engine from starting.
- ✔ The radio or infotainment system randomly shutting off or behaving strangely.
- ✔ Inconsistent instrument cluster gauge operation.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other U-series codes.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a manageable job for a DIY enthusiast. While the exact location can vary slightly, it’s typically found under the driver’s side dashboard. Always consult a service manual for your specific vehicle if you’re unsure.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes before beginning.
- Locate the BCM: On most 2015 Silverado/Sierra models, the BCM is located under the steering column, often attached to a bracket. You may need to remove a lower dash panel for access.
- Disconnect the Connectors: Carefully release the locking tabs on each electrical connector and pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt or unclip the old BCM from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and secure it.
- Reconnect Everything: Plug all electrical connectors firmly back into the new module. You should hear or feel a click as they lock into place. Reinstall any dash panels you removed.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions—lights, windows, locks, etc.
Important Post-Installation Notes
Our cloning service handles the vast majority of programming needs. However, due to the complexity of modern vehicle systems, a couple of additional steps may be required after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This re-establishes the security handshake between the BCM and the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation. This also requires a compatible diagnostic tool.
