Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2008-2012 Savana 1500 Van? Flickering lights, power windows with a mind of their own, or a security system that won’t cooperate are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it malfunctions, it can make your daily drive frustrating and unpredictable. Instead of facing a costly trip to the dealership for a new module and programming, our professional cloning service offers a direct, reliable, and affordable solution.
We simplify the repair process. By sending us your original BCM, we can perform a direct data transfer to this fully tested replacement unit. This means the replacement module arrives at your door pre-programmed with your vehicle’s specific VIN and RPO codes, making the installation process as close to plug-and-play as possible. This is the most efficient way to get your van, truck, or SUV back to 100% without the extra hassle and expense of dealer intervention.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry failing intermittently.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ False warning lights on the dashboard, such as the airbag light.
- ✔ Communication error codes, like U0140 (Lost Communication With Body Control Module).
A Technician’s Notebook
I had a 2011 Express work van come into the shop that was driving the owner crazy. The complaint was ‘intermittent electrical chaos.’ Sometimes the radio would shut off, other times the dome lights would stay on, draining the battery overnight. He’d already replaced the battery twice. A scan showed a handful of communication codes pointing towards the BCM. After confirming power and ground to the module were solid, we knew the BCM itself was the culprit. A cloned module like this one had him back on the road to his next job in under an hour of shop time, saving him a full day of lost work and the high cost of a dealer repair.
A Straightforward Guide to Installation
Our cloning service is designed to be simple for both DIYers and professional mechanics. Here is the process:
- Place Your Order: Purchase this BCM and we will await your original module.
- Send Us Your Module: Carefully remove your original BCM and ship it to us. We will provide shipping instructions after your purchase. Your original module will be returned to you with the replacement.
- We Clone It: Our technicians will professionally transfer all necessary data from your old BCM to the new one.
- Install and Go: Once you receive the programmed module, installation is straightforward. Disconnect the battery, swap the modules, and reconnect the battery.
Important Post-Installation Notes
In some cases, additional vehicle-specific relearn procedures may be required after installation. These are simple steps that sync the new module with other systems in your vehicle. The most common are:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to complete.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn may be necessary.
Disclaimer: Always refer to a factory service manual for your specific vehicle for detailed instructions and torque specs.

Frequently Asked Questions
Frequently Asked Questions
What is a ‘cloning service’?
Cloning is a process where we transfer the vital information—like your vehicle’s VIN and specific equipment options—from your original BCM directly onto the replacement unit. This makes the new module a perfect match for your vehicle, avoiding the need for expensive programming at a dealership.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we must have your original module to extract the necessary data. We will return your original module with your newly programmed replacement.
Is this part difficult to install?
For most DIYers with basic tools, swapping the BCM is a manageable job. It typically involves removing a few dash panels to access the module, unplugging the connectors, and swapping the unit. The main benefit of our service is that the complex programming is already done for you.
What tools are needed for the post-installation procedures?
While the physical installation requires only basic hand tools, procedures like the ‘Airbag System Sync’ must be done with a bi-directional, professional-grade diagnostic scan tool. Many local repair shops can perform these relearns for you if needed.
Will this fix my ‘Service Airbag’ light?
If the airbag light is caused by a faulty BCM or a communication issue between the BCM and the SDM (airbag module), this replacement will likely solve the problem. However, after installation, you may need to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
