DT43-2C219-DA | Genuine Ford® ABS Anti-Lock Brake Control Module

• Prevents Wheel Lock-Up

  • When a wheel locks, it stops rotating and skids across the road surface, reducing traction.

  • The ABS module continuously monitors wheel speed and modulates brake pressure to keep the wheels rotating just enough to maintain grip.

• Maintains Steering Control

  • By preventing wheel lock, the ABS system allows the driver to steer around obstacles even under heavy braking, rather than sliding uncontrollably.

• Reduces Stopping Distance (on most surfaces)

  • The system applies and releases brake pressure rapidly—many times per second—to achieve the shortest possible safe stopping distance without losing traction.

• Improves Vehicle Stability

  • ABS helps keep the vehicle stable and balanced during emergency stops or when braking on uneven or mixed-friction surfaces (like wet and dry patches).

• Enhances Driver Confidence and Safety

  • By automatically managing brake pressure and preventing skidding, ABS increases safety in critical driving conditions and reduces the likelihood of accidents.

1. ABS Warning Light On

• The most common and obvious sign.

• When the module detects a fault, it triggers the ABS light (and sometimes the brake or traction control lights) on the dashboard.

• The system may disable itself, reverting the vehicle to standard braking only.

2. Brakes Lock Up During Hard Braking

• If the ABS module fails, the system can’t regulate brake pressure.

• You might notice wheel lock-up or skidding when braking hard — especially on wet or icy roads.

3. Unresponsive or Hard Brake Pedal

• A bad ABS module or pump motor can cause inconsistent brake pressure.

• The pedal may feel hard, spongy, or unresponsive when pressed.

4. Pulsating or Inconsistent Brake Pedal

• Normally, a slight pulsation means the ABS is working correctly.

• However, constant or erratic pulsing, even in normal conditions, can indicate a failing module or sensor communication problem.

5. Speedometer or Traction Control Issues

• Some ABS systems share wheel speed sensors with the speedometer and traction control system.

• A malfunctioning module may cause incorrect speed readings or disable traction/stability control features.

6. Increased Stopping Distance or Poor Brake Performance

• The ABS might not activate when it should, causing longer stops or loss of steering control under heavy braking.

7. Communication or Diagnostic Trouble Codes (DTCs)

• Mechanics may find stored error codes like C0265, C0110, or U0121 — indicating electrical or communication faults in the ABS module.
