Is Your GM Vehicle Acting Possessed?
Are you dealing with a frustrating array of electrical gremlins in your Chevrolet, GMC, or Cadillac? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or random warning lights on your dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause widespread and unpredictable issues. Replacing it isn’t as simple as swapping parts, as the BCM is programmed specifically to your vehicle’s VIN and security system. This is where our expert programming service comes in.
We had a 2015 Silverado in the shop last month with the strangest symptoms. The radio would turn on and off by itself, the driver’s side power lock was intermittent, and the dome light would flicker randomly. The customer had already replaced the battery and checked all the fuses. After hooking up our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. A new BCM from the dealer would have required expensive programming and a tow to their facility. Instead, we used our cloning service. We transferred all the original data to a replacement unit, and the customer had it back in his truck the next day. All the electrical gremlins were gone—a perfect, hassle-free fix.
Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ False warnings appearing on the instrument cluster (e.g., ‘Service Airbag’).
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Horn honking randomly or not working at all.
- ✔ Wipers activating on their own or not responding to the switch.

Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a quick sync procedure after the new BCM is installed. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What is a BCM programming service?
It’s a process where we transfer the unique, vehicle-specific data from your original Body Control Module to a replacement unit. This makes the replacement module plug-and-play, avoiding the need for expensive dealership programming.
Why can’t I just install a used BCM from another vehicle?
A used BCM is programmed with another vehicle’s VIN and security information. Installing it will cause a mismatch, leading to a no-start condition and numerous system malfunctions. Our service ensures the module matches your exact vehicle.
How long does the entire process take?
Once we receive your original module, our programming service is typically completed within 1-2 business days. We then ship the programmed replacement back to you. Total turnaround time depends on shipping speeds.
What if my original BCM is damaged and unreadable?
In most cases, even with internal damage, we can still retrieve the necessary data. If your module is completely destroyed (e.g., by fire or severe water damage), please contact us before ordering to discuss potential options.
Is this a guaranteed fix for my vehicle’s electrical problems?
This service corrects issues directly caused by a faulty BCM. While the symptoms listed are common for BCM failure, it’s crucial to have your vehicle properly diagnosed by a professional to rule out other potential causes like wiring issues or faulty sensors.
