Is Your 2015 Sierra Denali Experiencing Bizarre Electrical Problems?
If your truck’s lights are flickering, windows and locks are acting erratically, or you’re seeing strange warning messages on the dash, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, controlling everything from the interior lights and power accessories to the security system. When it fails, it can cause a cascade of confusing and frustrating issues that can be difficult to diagnose and can even prevent your truck from starting.
The Simple, Plug-and-Play Solution
Forget expensive dealership visits and complex programming procedures. Our professional cloning service provides you with a replacement BCM that is a 100% plug-and-play solution. We transfer all the critical data from your original moduleāincluding key information, VIN, and vehicle-specific settingsādirectly onto a replacement unit. This ensures seamless integration and restores your truck’s functionality without any additional programming required.
How Our BCM Programming Service Works:
- ā Place Your Order: Complete your purchase through our secure checkout.
- ā We’ll Contact You: Our team will reach out with clear, simple instructions for shipping your original BCM to our facility.
- ā The Cloning Process: Once we receive your module, our technicians will perform a full data transfer to the replacement BCM.
- ā Fast Return Shipping: We ship your newly programmed module back to you, typically within 24-48 hours. You’ll receive tracking information as soon as it’s on its way.
Symptoms of a Failing 2015 Sierra Denali BCM
- ā Intermittent or non-functional power windows, door locks, or mirrors.
- ā Headlights, taillights, or interior lights behaving erratically (staying on or not turning on).
- ā The security system engaging randomly or preventing the engine from starting.
- ā Horn honking unexpectedly or not working at all.
- ā False warning lights or messages appearing on the instrument cluster (e.g., ‘Service Theft Deterrent System’).
- ā Wipers operating on their own or not responding to the switch.
- ā Complete loss of communication with the module, leading to a no-start condition.
Post-Installation Information
While our goal is a seamless installation, some GM vehicles may require minor electronic handshakes after a new module is introduced. Be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be needed to ensure proper operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Compatible Part Numbers:
This module is a direct replacement for the following part numbers: 13592137, 13506935, 13506936, 13587704, 13594764. Please verify that your original module’s part number is on this list to ensure compatibility.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, security system, and various other comfort and convenience features.
Why is your cloning service better than just buying a used BCM?
A standard used BCM from a junkyard is programmed to a different vehicle. It will not work correctly in your truck without being reprogrammed by a dealer, which is costly. Our service transfers your truck’s exact data, making the replacement unit a true plug-and-play part that works immediately upon installation.
How long does the entire process take?
Once we receive your original BCM, our cloning service is typically completed within 24-48 business hours. The total time depends on shipping transit times to and from our facility.
Will I need to have my keys reprogrammed?
No. Because we clone all the data from your original module, the replacement BCM will recognize your existing keys. This is a major benefit that saves you time and money.
What if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A qualified shop with a high-end scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
