Restore Your Vehicle’s Brain and End Electrical Frustrations
Are you dealing with bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or warning lights that won’t go away? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and costly problems. This replacement GM BCM 22915542 is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN.
Case Study: A Tricky Diagnosis
I remember a 2015 Chevy Traverse that came into my shop. The owner was at his wit’s end. The radio would turn on and off randomly, the liftgate wouldn’t open, and occasionally, the vehicle wouldn’t start, flashing a “Service Theft Deterrent System” message. He had already replaced the battery and checked fuses. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing to the BCM. A failing internal processor was causing intermittent network dropouts. We installed a VIN-programmed BCM like this one, and it was like giving the vehicle a new lease on life. All the strange electrical gremlins vanished instantly.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the vehicle from starting.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) appear for no reason.
- ✔ The horn honking or alarm sounding unexpectedly.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes like U0140, which indicates a loss of communication with the BCM.
- ✔ Wipers or radio operating incorrectly or not at all.
A Straightforward Guide to 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: On most compatible models, the BCM is found under the driver’s side of the dashboard (LH dash) or behind the center dash panel. A quick search for your specific model will confirm the exact location.
- ✔ Careful Disconnection: The BCM will have several multi-pin electrical connectors. Carefully press the release tabs on each connector and pull them straight out. Do not force them.
- ✔ Swap the Module: Remove the mounting screws or clips holding the old BCM in place. Install the new GM BCM 22915542 and secure it with the original hardware.
- ✔ Reconnect Everything: Firmly plug all electrical connectors into the new BCM. You should hear or feel a click as they lock into place.
- ✔ Power Up: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and check for proper function of lights, locks, and other accessories.
- ✔ Post-Installation Checks: Start the vehicle. As noted below, some vehicles may require additional procedures if specific warning lights appear.
Important Post-Installation Information
This BCM is programmed to your VIN for a seamless integration. However, in some cases, additional system handshakes are required after installation:
- ✔ Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only necessary if the light is on.
- ✔ Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and traction control system function.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN at checkout, and it will arrive ready to install with the latest GM software.
Is there a core charge or do I need to send my old part back?
There is absolutely no core charge. You can keep your old module, saving you the time and expense of a return shipment.
What happens if my airbag light comes on after I install it?
This is a possibility on some models. It means the new BCM needs to be electronically introduced to the airbag module. A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key’ procedure to resolve this.
Will this fix my vehicle not starting?
If your no-start issue is caused by the factory anti-theft system being triggered by a faulty BCM, then yes, this programmed module is designed to resolve that problem.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
