Tired of Chasing Electrical Gremlins in Your GM Truck?
If you’re dealing with flickering lights, power windows and locks with a mind of their own, or a security light that keeps your 2000 GMC Yukon from starting, you’ve likely met the classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM falters, it can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an annoyance; it can affect vehicle security and safety systems. Stop throwing parts at the problem and get the direct-fit, pre-programmed solution.
Case Study: A Tricky Diagnosis
I remember a 2000 Silverado in my bay that had its owner completely stumped. The dashboard would light up like a Christmas tree intermittently, the radio would cut out, and sometimes the truck wouldn’t crank, showing a ‘Security’ warning. The owner had already replaced the battery and alternator. After connecting my scan tool, I saw a handful of U-codes, indicating a loss of communication between modules. The culprit? An internally shorted BCM. We swapped in a VIN-programmed module like this one, and it was like the truck was new again. All the phantom electrical issues vanished instantly, saving the customer hundreds in further diagnostic time.
Is Your GM Truck or SUV Showing These Signs?
- âś” Intermittent or non-working power windows, door locks, or mirrors.
- âś” Flickering or erratic interior and exterior lights.
- âś” The security or anti-theft light is on, causing a no-start condition.
- âś” Inconsistent or non-functional dashboard gauges.
- âś” Blower motor for heat/AC works only on high or not at all.
- âś” Diagnostic Trouble Codes (DTCs) like U0140, B1001, or other communication errors.
- âś” False warnings on the driver information center.

A Straightforward Guide to Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- âś” Locate the BCM: On most of these GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, to the left of the steering column.
- âś” Remove Connectors: Carefully unplug the multiple wiring harnesses connected to the old module. They have release tabs that need to be pressed. Do not force them.
- âś” Unbolt the Old Module: Remove the bolts or nuts holding the BCM bracket in place and take the old module out.
- âś” Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely fasten it.
- âś” Reconnect Everything: Plug all wiring harnesses back into their correct slots on the new module. Reconnect the negative battery terminal.
- ✔ Perform Post-Install Checks: Start the vehicle and test all functions—lights, windows, locks, etc. Note that some vehicles may require the additional procedures listed below.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure your brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

No problem. This module is a direct replacement for service numbers 9385236, 19208539, and 9371990. As long as your vehicle is on the compatibility list, this module will work.
Is this a difficult part to install for a DIYer?
For most people with basic tools and some mechanical aptitude, this is a very manageable job. The BCM is typically accessible under the dash. The biggest benefit is that our pre-programming eliminates the need for special electronic tools.
Do I have to return my old BCM?
No. We do not require you to send back your original part. There is no core charge associated with this purchase.
What tools are needed for the post-install procedures?
The Airbag System Sync and Brake Pedal Position Relearn require a bi-directional professional diagnostic scan tool, like a GM Tech 2 or a high-end Snap-on or Autel scanner. Many local repair shops can perform these procedures for you if needed.
