Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Scan for Codes

Reconnect the battery and turn the ignition on without starting the engine.
Use an OBD-II scanner to retrieve and note any ABS or traction control fault codes.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor at the wheel hub.
Clean dirt or debris from the sensor area using a soft cloth.
Check the wiring harness for any visible damage; if damaged, replace the sensor.

4. Check ABS Module and Wiring

Locate the ABS control module, usually found near the brake master cylinder.
Inspect all wiring and connectors leading to the module for looseness or corrosion.
If a fault is found, repair or replace the faulty wiring or connectors.

5. Examine Brake Fluid

Open the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum lines.
If low, top off with the appropriate brake fluid (DOT 4). If contaminated, a brake fluid flush may be necessary.

6. Test Brake Pedal Switch

Locate the brake pedal switch, typically mounted on the brake pedal assembly.
Use a multimeter to test for continuity when the brake pedal is pressed.
If faulty, replace the brake pedal switch.

7. Tire Inspection

Inspect all tires for tread depth and uneven wear.
Ensure all tires are inflated to the manufacturer's recommended pressure.
Replace any tires that are excessively worn or damaged.
