Restore Full Functionality to Your GM Vehicle
Is your 2008-2012 Savana 1500 Van experiencing a host of frustrating electrical problems? From power windows that won’t budge to interior lights that flicker or a security system that acts up, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause unpredictable and widespread issues. This replacement BCM is the reliable, straightforward solution to get your van or other compatible GM vehicle back in perfect working order.
We take the guesswork and high costs out of the repair process. Unlike a generic module that requires a trip to the dealership for expensive programming, this unit arrives at your door ready for installation. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specific to your vehicle. This ensures seamless integration and proper function of all your vehicle’s features right out of the box.
Case Study: A Tricky Diagnosis
I remember a 2011 Savana work van that came into my shop with a laundry list of bizarre symptoms. The driver said the radio would randomly turn off, the driver-side power lock was dead, and sometimes the low beams wouldn’t turn on. A basic scan showed a dozen communication codes (U-codes) pointing in every direction. Instead of chasing each individual problem, my experience pointed to a central failure. We inspected the BCM and found evidence of water intrusion from a leaky windshield seal, a common issue on these workhorses. After installing a VIN-programmed 2008-2012 Savana 1500 BCM, every single one of the electrical gremlins vanished. It’s a perfect example of how one part can solve a multitude of problems.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM could be the root cause. This module is the definitive fix for these issues.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Dashboard warning lights appearing randomly (e.g., ABS, Airbag, Check Engine).
- ✔ Communication errors with other modules, often indicated by U-series diagnostic trouble codes (DTCs) like U0100, U0140.
- ✔ A no-start condition where the engine cranks but won’t fire due to security system lock-out.
A Straightforward Guide to Installation
Installing your new 2008-2012 Savana 1500 BCM is a manageable job for a DIYer with basic tools. For the Savana/Express vans, the BCM is typically located behind the center dash panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Access the Module: Carefully remove the necessary dash trim panels to gain access to the BCM. On the Savana, this is usually in the center dash area.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New BCM: Mount the new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearns (If Needed): Start the vehicle and check all functions. In some cases, as detailed below, a specific relearn procedure for the airbag or brake systems may be required using a compatible scan tool.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your old module. There is no core charge associated with this purchase.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, providing your VIN is essential. We use it to program the BCM with the correct software and vehicle-specific options from GM’s database. This step is what makes the installation process smooth and prevents compatibility issues.
Is this a difficult part for a DIYer to install?
For someone with basic mechanical skills and tools, this is a very manageable job. The main challenge is accessing the module behind the dash trim. Our pre-programming service eliminates the most difficult part: the computer setup.
Will this fix my ‘Service Airbag’ light?
If the BCM is the cause of the light, yes. However, after installation, the light may stay on until an ‘SDM Primary Key’ relearn is performed with a professional scan tool to sync the BCM to the airbag module. This is a standard security procedure.
What tools are needed for the post-installation procedures?
The Airbag Sync and Brake Pedal Relearn procedures require a bi-directional diagnostic scan tool, such as a Tech 2 or other high-end professional scanner. Most local repair shops have this equipment if you are unable to perform the procedure yourself.
Do I have to send my old BCM back?
No. This purchase does not require a core return. You can keep your original module.
