Programmed GM BCM 22915542 Body Control Module

Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution

Are you chasing down frustrating electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a no-start condition can all point to a single culprit: a failing Body Control Module (BCM). As an automotive technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant headaches. It’s the central hub for all your vehicle’s comfort and convenience features, and when it fails, chaos ensues.

This isn’t just a replacement part; it’s a complete, hassle-free solution. We take the biggest obstacle out of the equation—the programming. Simply provide us with your vehicle’s VIN at checkout, and our experts will flash this module with the latest, most stable software directly from GM. This means you can skip the expensive trip to the dealership for programming. This is the smart, efficient way to get your car, truck, or van back to 100% functionality.

Case Study: A Tricky Diagnosis

I remember a 2015 Chevy Express cargo van that came into the shop. The owner, a plumber, was at his wit’s end. The interior lights would stay on, draining the battery overnight, and the power door locks worked intermittently. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I found a series of U-codes (U0140, U0155) indicating a loss of communication with the BCM. Instead of a complex wiring repair, the fix was a new GM BCM 22915542. Once a pre-programmed unit was installed, all the phantom electrical issues vanished instantly. It saved him hours of lost work and diagnostic fees.

Common Signs of a Failing BCM

If your vehicle is exhibiting any of these symptoms, a failing BCM is the likely cause. A faulty module can trigger various diagnostic trouble codes (DTCs), most commonly communication errors (U-codes) or body-specific faults (B-codes).

✔ Erratic or non-functional power windows, door locks, and mirrors.
✔ Interior or exterior lights flickering, staying on, or not working at all.
✔ Horn honking randomly or not working when pressed.
✔ Vehicle security system faults or alarm sounding unexpectedly.
✔ Instrument cluster gauges behaving erratically or going dark.
✔ A/C and climate control system malfunctions.
✔ Intermittent no-start condition where the engine cranks but won’t fire up.

Your Straightforward BCM Installation Guide

Replacing the BCM is a manageable job for a confident DIYer. Our pre-programming service eliminates the most difficult step. Always prioritize safety and consult a service manual for your specific vehicle’s location and torque specs.

Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down completely.
Locate the BCM: On most of these models, the BCM is located under the driver’s side of the dashboard (LH dash) or behind the center dash panel in vans. You may need to remove a few plastic trim panels for access.
Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
Install the New Module: Mount your new, pre-programmed BCM in the same location. Secure the bolts and then firmly reconnect all the electrical harnesses. You should hear a ‘click’ as they lock into place.
Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, horn, and wipers.
Perform Post-Install Procedures: In some cases, additional steps are needed. If the airbag light is on, an ‘SDM Primary Key Setup’ is required. A ‘Brake Pedal Position Relearn’ may also be necessary for proper traction control function. These procedures require a professional-grade scan tool.
