Is Your GM Truck or SUV Plagued with Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a no-start condition, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated issues. This module is a direct-fit, VIN-programmed solution for your vehicle, designed to restore full functionality and get you back on the road with confidence.
From the Diagnostic Bay
We had a 2002 GMC Sierra in the shop that was driving the owner crazy. The dome lights wouldn’t turn off, the radio would randomly change stations, and the power locks worked intermittently. He had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. Instead of a dozen separate problems, it was one single point of failure. By installing a VIN-programmed 2002 Sierra Body Control Module, we resolved all the electrical issues in one go, saving the customer hundreds in diagnostic time and unnecessary parts.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Warning lights on the dashboard, including the airbag light.
- ✔ Intermittent no-start or crank-no-start conditions.
- ✔ Unpredictable behavior from the radio or climate controls.

Important Post-Installation Information
While this BCM is programmed for your vehicle, some models may require additional vehicle-specific relearn procedures after installation. This is a normal part of the repair process. You may need a professional diagnostic tool to perform:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a recalibration of the brake pedal position sensor may be required.
We also make the process easier with our no core charge policy. You can keep your old module without any extra fees or the hassle of a return shipment.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and interior accessories.
Does this BCM need to be programmed?
No, we handle the programming for you. Simply provide your vehicle’s VIN when you order, and we will flash the module with the latest GM software specific to your truck or SUV before we ship it.
How do I find my original BCM part number?
The part number is printed on a sticker on the case of your original BCM. You will need to locate and remove the module, typically found under the steering column or in the center dash area, to read the label.
What if my airbag light is on after I install this part?
This is a common occurrence. It means the new BCM needs to be synced with your vehicle’s airbag system (SDM). A mechanic with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is this a difficult part to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. However, as noted, some post-installation electronic relearn procedures may be necessary for full functionality.
Do I have to return my old BCM?
No. This product comes with no core charge, so you are not required to send your original part back to us.
