Is Your GM Vehicle Plagued by Bizarre Electrical Issues?
The Body Control Module (BCM) is the central command center for your vehicle’s electronics. It manages everything from your power windows and door locks to the interior lighting, security system, and even communication between other critical modules. When the BCM starts to fail, it can create a cascade of confusing and frustrating problems that seem unrelated. If you’re dealing with intermittent electrical gremlins, a faulty BCM is often the culprit.
From the Diagnostic Bay
We had a 2015 Sierra 1500 in the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome light would flicker, and occasionally the power locks wouldn’t respond. He had already replaced the radio head unit and a door lock actuator with no success. After hooking up our diagnostic scanner, we saw multiple communication error codes pointing to a network issue. We traced the problem to the BCM, which was failing intermittently. Instead of a costly trip to the dealer for a new module and programming, we provided a cloned BCM. The customer installed it himself in under an hour, and all the strange electrical issues were gone for good. It saved him hundreds in diagnostic time and dealership programming fees.
Symptoms of a Failing Body Control Module
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs attention:
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not working.
- ✔ The vehicle’s security system malfunctioning or triggering the alarm randomly.
- ✔ Dashboard warning lights appearing without a clear cause (e.g., airbag, ABS lights).
- ✔ Key fob not being recognized or working intermittently.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ The vehicle failing to start due to anti-theft system issues.
The Simple, Plug-and-Play Solution: Our BCM Cloning Service
Don’t spend a fortune at the dealership for a new module and expensive programming. Our professional cloning service is the most efficient and cost-effective way to get your vehicle back on the road. We transfer all the critical data from your original, failing BCM directly onto a replacement unit. This includes the Vehicle Identification Number (VIN), key programming, and other vehicle-specific settings. The result is a true plug-and-play module that requires no additional programming upon installation.

Important Post-Installation Information
While our goal is a seamless installation, some GM vehicles may require minor recalibration procedures after the new 2015 Escalade BCM is installed. These are simple steps that can often be performed with a capable diagnostic tool:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains vital security and vehicle-specific data, including your key programming and VIN. By cloning this data to the replacement module, we create a true plug-and-play part, saving you from expensive and complex dealership programming.
How long does the cloning service take?
We typically complete the programming and ship your replacement BCM back to you within 1-2 business days of receiving your original module.
Will I need to get my keys reprogrammed?
No. Because we clone all the data from your original module, the replacement BCM will recognize your existing keys just like the original did. No key programming is required.
Is this a difficult part to install?
For most vehicles listed, like the 2015 Escalade, the BCM is located under the steering column or in the driver’s side dash area. It’s typically held in with a few bolts and has several electrical connectors. Installation is straightforward for anyone with basic mechanical skills.
What if the airbag light comes on after I install the new BCM?
This is a known possibility on some GM platforms. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
