Is Your GM Truck or Van Plagued by Bizarre Electrical Problems?
If you’re dealing with flickering lights, power windows with a mind of their own, or a security system that won’t cooperate, the culprit is likely a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from interior lighting and door locks to the instrument cluster and security features. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Don’t let a faulty module keep you off the road. This is your direct-fit, VIN-programmed solution.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would stay on intermittently, the radio would shut off randomly, and the power door locks worked only when they felt like it. The customer had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing towards the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed BCM like this one. The new module restored communication between all the components instantly. All the strange electrical gremlins vanished, and the truck was back to being the reliable workhorse it was meant to be. It’s a classic case of the central hub failing and causing chaos downstream.
Symptoms of a Failing Body Control Module
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement. This replacement 2003-2006 SSR BCM is designed to resolve these exact problems.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not working at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Instrument panel gauges behaving erratically or warning lights appearing for no reason.
- ✔ The radio or infotainment system randomly turning on or off.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with other vehicle modules, often flagged by a professional scan tool.

This means no extra programming is needed on your end. It’s a plug-and-play repair that gets you back on the road faster.
This module is a direct replacement for a wide range of GM trucks and vans, including the Chevrolet SSR, Silverado, Sierra, Express, and Savana. It is compatible with the following original equipment part numbers:
Compatible Part Numbers: 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, 10367689
Installation and Post-Install Considerations for Your 2003-2006 SSR BCM
Installation is straightforward for a DIY mechanic with some experience. The BCM is typically located under the steering column on pickup trucks or in the center dash area on vans. Once the new module is installed, there are a couple of potential procedures that may be required, depending on your specific vehicle.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is because the new BCM needs to be electronically ‘introduced’ to the airbag system’s SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and clear the light.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure your brake lights and traction control system function as intended. This is also performed with a capable diagnostic tool.
We make the process easy with no core charge. You can keep your old module without the hassle of shipping it back. Restore your vehicle’s functionality and peace of mind with a reliable, pre-programmed BCM.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your exact vehicle.
Is this a difficult part to install myself?
For someone with moderate mechanical skill, the physical replacement is not overly complex. It typically involves removing a few dash panels to access the module. However, be aware that post-installation procedures like the Airbag System Sync may require a professional-grade scan tool that most DIY mechanics do not own.
What happens if I don’t perform the post-install procedures?
These procedures are only necessary if you experience specific symptoms after installation. If the airbag light comes on, it will stay on until the sync procedure is completed. If the brake pedal position is not relearned, you may have issues with brake light operation or traction control warnings. The vehicle will likely still be drivable, but these safety systems will not be fully functional.
Will this BCM fix a ‘No Start’ condition?
While a BCM can contribute to a no-start condition, particularly related to the vehicle’s anti-theft system (Passlock/Passkey), it’s not the most common cause. A no-start issue should be properly diagnosed to rule out other components like the starter, battery, ignition switch, or fuel system before replacing the BCM.
Do I need to return my old BCM?
No. This product has no core charge. You are free to keep or dispose of your original module as you see fit.
