Is Your GM Vehicle Acting Possessed? It Could Be The BCM.
The Body Control Module (BCM) is the central command center for your vehicle’s electronic accessories. It controls everything from your power windows and door locks to the interior lights, security system, and even communication with other modules. When the BCM starts to fail, it can create a cascade of bizarre and frustrating electrical problems that can be difficult to diagnose. Instead of paying for expensive diagnostics and programming at the dealership, our professional cloning service provides a simple, cost-effective, and reliable solution.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or alarm acting erratically or preventing the car from starting.
- ✔ Key fobs and remote entry failing to work consistently.
- ✔ Instrument cluster gauges behaving strangely or warning lights appearing for no reason.
- ✔ Radio or infotainment system issues, such as staying on after the key is removed.
- ✔ A no-start condition where the starter doesn’t engage, even with a good battery.
From the Diagnostic Bay
We had a 2015 Sierra 1500 in the shop that was driving the owner crazy. The dome lights would flicker randomly, the radio wouldn’t shut off with the door open, and sometimes the power locks wouldn’t respond. The scanner showed no communication codes, which pointed towards a network issue. After checking the wiring, we isolated the problem to the BCM. Instead of a new module and a trip to the dealer for programming, we used our cloning service. We transferred the data from his original module to a replacement unit. After a quick install, every single electrical gremlin was gone. It’s a perfect example of how a faulty BCM can create phantom issues that are easily solved with the right part and process.

Important Post-Installation Information
While our cloning process makes this a plug-and-play part, some vehicle systems may require a simple sync procedure after installation. 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 is necessary. This requires a professional-grade scan tool to sync the airbag system with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM cloning service?
BCM cloning is a process where we transfer the exact vehicle-specific data—including the VIN, security information, and equipment options—from your original BCM to a replacement unit. This makes the replacement module a plug-and-play part, eliminating the need for dealership programming.
Why is this better than buying a used BCM from a junkyard?
A standard used BCM will have the data from the donor vehicle and will not work in your car without being reprogrammed by a dealer, which is costly. Our service provides you with a fully functional module that is already programmed specifically for your vehicle’s VIN and options.
How long does the entire process take?
Once we receive your original BCM, our technicians typically complete the cloning service within 1-2 business days. We then ship the replacement module back to you. Total turnaround time will depend on shipping speeds.
Will my existing keys and key fobs work immediately?
Yes. Because we clone all the security data from your original module, your existing keys and remotes will be recognized by the replacement BCM and will work immediately upon installation without any additional pairing procedures.
What if I have an airbag light on after installing the BCM?
This is a known possibility. The airbag module (SDM) may need to be electronically ‘introduced’ to the new BCM. A technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back after I get the replacement?
No, there is no core charge for this part. You send us your original BCM for the data cloning service, and we send you a different, fully programmed replacement unit. You can keep your original module.
