Are you chasing down bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or even a no-start condition can all point to one central component: a failing Body Control Module (BCM). As the nerve center for your vehicle’s body electronics, a faulty BCM can create frustrating and unpredictable problems. This replacement GM Body Control Module is the definitive solution, arriving at your door pre-programmed with the latest GM software specific to your vehicle’s VIN.

Simply provide your VIN during checkout, and our technicians will flash the module, ensuring it communicates seamlessly with your vehicle’s existing systems right out of the box. This restores original functionality and performance, getting you back on the road with confidence.

Common Signs of a Failing BCM

If you’re experiencing any of the following, a faulty BCM is the likely culprit. This module is designed to correct these exact issues:

• ✔ Erratic or non-functional interior and exterior lights.
• ✔ Power windows, locks, or mirrors working intermittently or not at all.
• ✔ The security system or keyless entry failing to operate correctly.
• ✔ Unexplained battery drain while the vehicle is off.
• ✔ False warnings on the dashboard, such as “Service Theft System.”
• ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes.
• ✔ Inability for a scan tool to communicate with various modules.

A Straightforward Guide to Installation

Replacing the BCM is a manageable job for a DIY enthusiast. While the location varies slightly by model (check your service manual), the general process is consistent.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
2. Locate the BCM: It’s typically found under the driver’s or passenger’s side of the dashboard, or behind a kick panel. The fitment list below provides common locations.
3. Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
4. Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module and remove it.
5. Install the New Module: Mount your new, pre-programmed BCM in the same location and reconnect all electrical connectors, ensuring they click securely into place.
6. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, windows, locks, radio, etc.—to confirm proper operation.

Important Post-Installation Notes

While this module is programmed for your VIN, some vehicle systems may require a relearn procedure to sync with the new BCM. This is normal. Key procedures include:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only required if the light is on.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be needed to ensure correct brake light and traction control operation.

Always consult your vehicle’s factory service manual for detailed, model-specific instructions.
