12474925 | Genuine GM® Electronic Brake Control Module Kit

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.

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
