Restore Your Van’s Electrical Systems with a VIN-Programmed BCM
If your 2008-2012 Savana 2500 Van is plagued by baffling electrical problems, a failing Body Control Module (BCM) is often the culprit. As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of issues that seem unrelated, from flickering lights to a no-start condition. This isn’t just an inconvenience; it can be a major disruption for your work or daily life. I’ve seen it countless times in my 20 years on the shop floor: a perfectly good engine that won’t start or a van with a mind of its own, all because this one module has failed.
We offer a dependable and straightforward solution. This BCM, part number 15828601, is a direct-fit replacement that arrives at your door pre-programmed to your van’s specific Vehicle Identification Number (VIN). This means you can skip the expensive trip to the dealership, avoid towing fees, and eliminate the hassle of scheduling a programming service. We handle the complex part so you can focus on the simple installation.
Case Study: A Tricky Diagnosis
A local contractor brought in his ’11 Savana 2500, completely frustrated. The instrument cluster would randomly go dark, the radio would cut out, and sometimes the power locks wouldn’t respond. He’d already replaced the battery and checked the alternator. After hooking up the scan tool, I saw a flurry of U-codes (U0140, U0155) indicating a loss of communication with the BCM. Before condemning the module, we checked the main power and ground connections at the BCM connectors, as corrosion is a common issue. The connections were solid. This confirmed our diagnosis: the BCM itself had an internal fault. Installing a VIN-programmed module like this one resolved all the issues in under an hour, getting him back to his job site the same day.
Is Your Van Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs attention. Look out for these common signs:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly, possibly triggering the alarm randomly.
- ✔ Instrument panel gauges giving incorrect readings or ceasing to function.
- ✔ The vehicle failing to start, accompanied by a security light on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0155, or BCM internal failure codes.
A Straightforward Guide to Your BCM Installation
Replacing the BCM in your Savana or Express van is a manageable job for a DIYer with basic tools. Our pre-programming service makes it even simpler. Follow these general steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: In most Savana and Express vans, the BCM is located in the center dash area, often accessible by removing lower dash panels. Consult a service manual for your specific model’s exact location.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same position as the old one. Securely plug in all the electrical connectors, ensuring they click into place.
- Reconnect Power: Reconnect the negative battery terminal.
- Perform Final Checks: Turn the key to the ‘On’ position and test all body functions: lights, wipers, locks, windows, etc. Note that some vehicles may require post-installation procedures as detailed below.
Important Post-Installation Information
While our programming handles the majority of the setup, some GM vehicles require a final handshake between modules after installation. Be aware of these potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your old BCM. There is no core charge or deposit associated with this purchase.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a certified technician for procedures specific to your vehicle.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to the VIN you provide before shipping. This makes the installation process much simpler for you.
What does the Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls functions like power windows, power locks, interior and exterior lighting, the security system, wipers, and instrument panel warnings.
Is there a core charge for my old part?
No, there is no core charge. You can keep or dispose of your original module without needing to send it back to us.
Will this fix my ‘Service Airbag’ light?
If the BCM was the cause of the light, yes. However, after installation, the new BCM may need to be electronically synced with the airbag module (SDM) using a scan tool to turn the light off. This is a standard security procedure.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit VIN. We cannot program and ship your BCM without it.
