12474925 | Genuine GM® Electronic Brake Control Module Kit

An Electronic Brake Control Module 12474925 (EBCM) is a critical component in modern vehicles’ braking systems, especially those equipped with ABS (Anti-lock Braking System) and traction control. It’s an electronic control unit that monitors and regulates brake functions to improve safety and stability.

General Specifications

Fitment

Fitment can vary by engine build and options. Match the part number on the part you are replacing, or contact us with your vehicle details before ordering.

Purpose & Function

1. Control ABS (Anti-lock Braking System)

• Prevents wheels from locking during hard braking.

• Maintains steering control during emergency stops.

2. Manage Traction Control

• Reduces wheel spin on slippery surfaces by modulating brake pressure and/or engine power.

3. Stability Control

• Works with ESC (Electronic Stability Control) to prevent skidding during sharp turns or evasive maneuvers.

4. Coordinate Brake Pressure

• Electronically controls hydraulic pressure to individual wheels as needed for safety.

5. Communicate with Vehicle Systems

• Sends brake-related data to the dashboard (ABS warning light, traction control light, etc.) and other vehicle modules.

Signs of Bad Electronic Brake Control Module

1. ABS Warning Light Stays On

• The dashboard ABS light (sometimes with traction control light) turns on and stays on.

• Indicates the module has detected a problem or lost communication with sensors.

2. ABS Doesn’t Activate

• During hard braking, the pedal doesn’t pulse.

• You may hear no ABS pump noise.

• Wheels can lock up, especially on slippery surfaces.

3. Brakes Lock Up or Skid

• Without proper control from the module, the ABS cannot modulate brake pressure.

• Wheels may lock during braking, increasing the risk of losing steering control.

4. Brake Pedal Problems

• Pedal may feel hard, soft, or spongy.

• Brakes may respond inconsistently.

5. Traction Control or Stability Control Lights On

• Systems like TCS or ESC often rely on the ABS module.

• A failing module can trigger multiple warning lights.

6. Erratic ABS Behavior

• ABS may engage randomly without heavy braking.

• Pulsing or vibration in the brake pedal at normal speeds.

• Strange buzzing or grinding noises from the brake system.

7. Speedometer or Wheel Data Issues (in some vehicles)

• If the module provides wheel speed data, you may see speedometer jumping or inaccurate readings.

8. Diagnostic Trouble Codes (DTCs)

• Scan tools may show ABS module-related errors:

  • Communication failures

  • Sensor circuit failures

  • Pump or valve errors
