Is Your GM Vehicle Plagued by Baffling Electrical Problems?
Are you dealing with flickering lights, power windows with a mind of their own, or a security system that randomly goes off? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your interior lights and power locks to the instrument cluster and anti-theft system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues, making your vehicle unreliable and difficult to diagnose.
From the Diagnostic Bay
We recently had a 2005 Silverado 2500 towed in that was driving its owner crazy. The radio would turn on and off, the dome light would stay on, and sometimes the truck would refuse to start, displaying a ‘Security’ message. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and programming fees, we installed one of our VIN-programmed BCMs. The entire process was done in under an hour, and all the strange electrical gremlins vanished. It’s a perfect example of how the right part, correctly prepared, can save immense time and frustration.
Why Choose a VIN-Programmed SSR Body Control Module?
Replacing a BCM isn’t as simple as swapping out a fuse. Modern vehicle modules are coded specifically to the vehicle’s unique Vehicle Identification Number (VIN) and its specific options. Our service eliminates the guesswork and the need for expensive dealership programming. When you order this SSR Body Control Module, we use the VIN you provide to flash the unit with the latest official GM software and calibrate it precisely for your truck or van’s configuration. This ensures that when you receive the part, it’s ready for installation, integrating seamlessly with your vehicle’s other electronic systems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, flickering).
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Problems with the keyless entry or remote start system.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (U-codes).
- ✔ Inconsistent operation of windshield wipers or radio controls.
Installation and Post-Install Considerations
This BCM is a direct-fit replacement, making the physical installation straightforward for a DIY mechanic or any professional technician. On most pickup trucks like the Silverado and Sierra, you will find it located under the steering column. On vans like the Express and Savana, it’s typically behind the center dash. While our VIN programming handles the majority of the setup, some GM vehicles may require a couple of simple relearn procedures after installation to ensure all systems are communicating correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag module and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor may be necessary for correct brake light and traction control operation.
This module is a direct replacement for several part numbers, including: 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689. Restore your vehicle’s electronic functions and reliability today.
Frequently Asked Questions
Why do I need to provide my vehicle’s VIN?
Your vehicle’s VIN is essential because it allows us to program the Body Control Module with the exact software and settings for your specific make, model, year, and factory options. This ensures a plug-and-play installation and proper function of all electronic features without a trip to the dealership.
Is this a difficult part to install myself?
The physical replacement of the BCM is generally straightforward for someone with basic mechanical skills. It usually involves removing a few dash panels to access the module. However, be aware that post-installation procedures like an airbag system sync may require a professional scan tool that most DIYers do not own.
What happens if my airbag light is on after I install the BCM?
If the airbag light comes on, it means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). This is a security feature. A technician with a capable bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this BCM fix my specific electrical problem?
This BCM will correct issues directly caused by a faulty module. If you are experiencing several of the symptoms listed (erratic lights, window/lock failure, security faults), a failing BCM is the most likely culprit. However, we always recommend proper diagnostics to rule out other potential causes like wiring issues or faulty switches.
Is there a core charge for my old BCM?
No, there is no core charge for this part. You can keep your original module without needing to send it back to us.
