Restore Your Vehicle’s Electrical Sanity
Are you tired of chasing electrical gremlins in your GM vehicle? One minute the power windows work, the next they don’t. The security light flashes for no reason, your key fob is unresponsive, or the interior lights have a mind of their own. As a technician with over two decades of experience, I’ve seen these exact frustrations hundreds of times. More often than not, the culprit is a failing Body Control Module (BCM). It’s the central hub for your car’s comfort and convenience features, and when it starts to go, it can make your vehicle feel haunted.
This isn’t just a replacement part; it’s a complete solution. We take the biggest headache out of the repair process: programming. Simply provide us with your vehicle’s VIN during checkout, and our experts will program this GM Body Control Module with the latest GM software specifically for your car or truck. It arrives at your door ready for installation, saving you a costly trip to the dealership and the hassle of coordinating programming services. This is the reliable, straightforward fix you’ve been looking for.
From the Diagnostic Bay: The Case of the Frustrating Express Van
A local contractor brought in his 2011 Express 3500 work van with a list of bizarre complaints. The dome lights wouldn’t turn off, draining the battery overnight, and the power locks only worked intermittently. He’d already replaced the battery and checked all the fuses. On the scan tool, I found a slew of communication codes (U-codes) pointing to the BCM. Instead of a complex wiring issue, the internal logic of the original BCM had simply failed. We installed a VIN-programmed module just like this one, and in under an hour, every single issue was resolved. It’s a textbook example of how a failing GM Body Control Module can cause multiple, seemingly unrelated problems.
Is Your Vehicle Showing These Classic BCM Failure Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system or alarm being triggered randomly.
- ✔ Key fobs that stop working or work intermittently.
- ✔ Dashboard warning lights (like the airbag or security light) illuminating.
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes.
- ✔ A no-start condition where the starter doesn’t engage due to a security system fault.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a manageable task for a confident DIYer. While locations vary (check your vehicle’s fitment details below), the general process is similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to allow the systems to discharge completely.
- Locate the BCM: The BCM is typically found under the driver’s or passenger’s side of the dashboard, or behind a kick panel. On vans, it’s often in the center dash area.
- Disconnect and Remove: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or lifted. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Relearns (If Needed): Start the vehicle. In some cases, you may need to perform additional procedures as outlined in our post-installation notes. For example, if the airbag light is on, a scan tool is needed to sync the systems.
Post-Installation Requirements & Notes
Your BCM comes programmed for a seamless installation, but some vehicle systems may require a ‘handshake’ with the new module. Please be aware of the following potential procedures:
- ✔ Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
- ✔ No Core Charge: You are not required to return your old module. This saves you time and the cost of return shipping.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual for procedures specific to your make and model.

Frequently Asked Questions
Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Every GM Body Control Module is specific to the options and security system of the vehicle it’s installed in. We program the module using your VIN to ensure it works correctly right out of the box.
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a very manageable job. The most difficult part is typically accessing the module under the dash. Since we handle the programming, the technical barrier is much lower.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). This procedure, called ‘Setup SDM Primary Key in BCM’, requires a high-end diagnostic scan tool and can be performed by most professional repair shops.
Will this fix my check engine light?
Generally, no. The BCM controls body functions, while the Engine Control Module (ECM) or Powertrain Control Module (PCM) monitors engine and transmission performance, which triggers the check engine light. A BCM failure typically causes other warning lights, like the security or airbag light.
Do I have to send my old BCM back?
No. We do not require a core return for this part. You can keep your original module, which saves you the hassle and expense of shipping it back.
Is this part new or used?
This is a quality, tested, and verified recycled OEM part that has been programmed with the latest software for your vehicle, ensuring reliable performance and perfect fitment.
