Are you battling bizarre electrical issues in your GM truck, van, or Chevrolet SSR? From flickering lights and malfunctioning power windows to a security system that has a mind of its own, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central hub for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement BCM, part number 15747545, is the reliable, direct-fit solution to restore full functionality and peace of mind.
To ensure a seamless installation, we program this module specifically to your vehicle using the VIN you provide at checkout. This critical step loads the correct software and vehicle-specific options, making the installation process as straightforward as possible. Say goodbye to expensive dealership programming fees and lengthy wait times.
We had a 2005 Silverado 2500 in the shop that was driving the owner crazy. The dome light would stay on, the radio presets would randomly reset, and the power locks worked intermittently. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a complex wiring issue, it was a simple module failure. We installed a VIN-programmed BCM just like this one, and all the strange electrical gremlins vanished instantly. It’s amazing how many systems this one module controls.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing to operate.
- ✔ The horn sounding unexpectedly or not at all.
- ✔ Warning lights on the dashboard illuminating for no reason.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ Communication issues with other vehicle modules, leading to a no-start condition.
Installation and Post-Install Steps for Your 2003-2006 SSR BCM
This module is designed for a direct-fit replacement. After providing us with your VIN, we will program the module so it arrives ready to be installed. While many installations are plug-and-play, some vehicles may require additional steps after the new BCM is connected. These are known as ‘relearn’ or ‘synchronization’ procedures and typically require a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function as intended.
This BCM is a direct replacement for a variety of part numbers, including: 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689. Please verify your part number and consult the fitment list to ensure compatibility.
Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your vehicle’s 17-digit VIN (Vehicle Identification Number) is essential for us to program the BCM with the correct software and settings for your specific model, year, and options. This ensures the module communicates correctly with your vehicle’s other systems right out of the box.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. It’s usually located under the steering column or in the center dash area. However, some vehicles may require post-installation procedures with a scan tool, as noted in the description.
Do I have to send my old part back?
No, there is no core charge for this part. You can keep your original module.
What happens if my airbag light comes on after I install this?
If the airbag light is on, it means the new BCM needs to be synchronized with your vehicle’s airbag module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be done by a qualified technician with a professional diagnostic tool.
Will this fix my specific electrical problem?
This BCM is the solution for a wide range of electrical issues caused by a faulty module. If your vehicle is exhibiting several of the symptoms listed, a failing BCM is the likely cause. However, proper vehicle diagnosis is always recommended to rule out other issues like bad wiring or grounds.
