Is Your GM Truck or Van Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows with a mind of their own, or a security system that randomly acts up? These frustrating and unpredictable issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, coordinating everything from the dome light to the power locks. When it starts to fail, it can create a cascade of bizarre problems that are difficult to diagnose. Don’t let a faulty module compromise your vehicle’s functionality and your peace of mind.
Common Symptoms of a Failing GM BCM
- ✔ Erratic interior or exterior lights that flicker, stay on, or fail to turn on at all.
- ✔ Power windows, door locks, or mirrors working intermittently or not responding.
- ✔ Malfunctions with the keyless entry or factory security system (PassLock).
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Warning lights, such as the airbag or security light, illuminating on the dash.
- ✔ A no-start condition caused by the security system disabling the vehicle.
- ✔ Battery drain from components staying active after the vehicle is turned off.

Installation and Required Procedures
Physically installing the BCM is typically a straightforward process, as it is usually located under the driver’s or passenger’s side of the dashboard. Once the new module is connected, your vehicle’s core functions will be restored. However, depending on your specific model, a couple of additional electronic ‘handshake’ procedures may be necessary.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system’s computer and must be performed with a compatible high-level scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light operation and traction control functionality.
We also make the process easier with our No Core Charge policy. You can keep your original module without the hassle of packaging and shipping it back to us.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for the specific options your vehicle was built with, such as keyless entry, power accessories, and security system type. This ensures seamless integration and proper function.
Is this part difficult to install myself?
The physical replacement of the BCM is generally simple for someone with basic mechanical skills, as it’s usually accessible under the dashboard. However, be aware that post-installation electronic procedures, like an airbag system sync, may be required and necessitate a professional diagnostic tool.
What if my airbag light is on after I install it?
If the airbag light comes on, it means the new BCM needs to be electronically synced with the airbag’s Sensing and Diagnostic Module (SDM). This procedure, often called ‘Setup SDM Primary Key in BCM’, must be performed by a technician with a compatible scan tool to clear the light.
Do I have to send my old BCM back?
No. We do not require you to return your original module. This part is sold with no core charge, saving you the time and expense of a return shipment.
Will this BCM fix my truck not starting?
It can, if the no-start condition is caused by the vehicle’s PassLock anti-theft system, which is controlled by the BCM. A failing BCM can improperly activate the security system, preventing the engine from starting. This programmed module will restore that function.
