Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you tired of chasing down bizarre electrical gremlins in your GM truck, car, or SUV? One minute the power windows work, the next they don’t. Maybe your dash lights are flickering, or the security system is acting up, preventing your vehicle from starting. These frustrating and often intermittent issues 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 cause widespread chaos. This professionally programmed 2015-2016 GM BCM is the definitive solution, designed to restore full functionality without the exorbitant costs and scheduling headaches of a dealership visit.
Our unique service makes this repair straightforward for both professional technicians and DIY enthusiasts. Instead of shipping you a blank module that requires special tools for programming, we handle the complex part for you. Simply send us your original BCM, and we will transfer all the vital vehicle-specific data—including VIN, mileage, and security information—to this quality replacement unit. We then ship it back to you, ready for a simple plug-and-play installation. This process ensures perfect compatibility and preserves all your vehicle’s original features.
Case Study: A Tricky Diagnosis
I remember a 2015 GMC Sierra 1500 that came into the shop with a laundry list of complaints from the owner. The radio would randomly shut off, the dome light wouldn’t work, and occasionally, the truck would refuse to crank. The owner had already replaced the battery and checked the main fuses. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing to a network problem. Instead of just replacing parts, I monitored the data stream from the BCM. I noticed the BCM would intermittently drop offline, causing all the secondary issues. This is a common failure mode I’ve seen in hundreds of these GM vehicles. A new BCM from the dealer would have required programming, adding time and cost. By cloning his original module’s data onto our replacement 2015-2016 GM BCM, we had him back on the road the next day with a reliable, cost-effective repair that solved every single one of his issues.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) flickering or failing to turn on/off.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Vehicle security system engaging randomly, causing a no-start condition.
- ✔ Warning lights on the dashboard for systems controlled by the BCM.
- ✔ Communication error codes stored, such as U0140 (Lost Communication with BCM).
- ✔ Wipers behaving erratically or not parking in the correct position.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all modules to power down completely.
- ✔ Locate the BCM: On most compatible models, the BCM is located under the driver’s side of the dashboard, near the steering column or left-hand kick panel. Refer to a vehicle-specific service manual for the exact position.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, remove any bolts or clips securing the module and take it out of the vehicle.
- ✔ Install the New Module: Position your newly programmed BCM in the same location and secure it with the original bolts or clips.
- ✔ Reconnect Everything: Firmly plug the electrical connectors into the new module, ensuring each one clicks into place. Reconnect the negative battery terminal.
- ✔ Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair was successful.
Important Post-Installation Note: In some cases, additional relearn procedures may be necessary. If the airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. A ‘Brake Pedal Position Relearn’ might also be required for proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific requirements.

Frequently Asked Questions about our 2015-2016 GM BCM
How does the mail-in programming service work?
After you place your order, we will contact you with simple instructions and a shipping address. You mail your original BCM to us. Once we receive it, we transfer its data to the replacement module and ship it back to you the same or next business day, ready to install.
Is this truly plug-and-play?
Yes. Because we clone the data from your original module, the replacement unit is recognized by your vehicle’s other computers, eliminating the need for dealer programming. In rare cases, a simple relearn procedure for the airbag or brake pedal sensor may be needed, as noted in the description.
Do I need to send my key fob?
No, you do not need to send your keys or key fobs. All key fob information is stored in your original BCM and will be transferred during the cloning process, so your existing keys will work perfectly.
What is the turnaround time?
We pride ourselves on a fast turnaround. We typically program and ship your replacement module the same or next business day after we receive your original unit. We will provide you with a return tracking number as soon as it ships.
Is there a core charge?
No, there is no core charge for this service. You can keep your original module after you’ve sent it to us for the data transfer.
