Solution

1. Preparation

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

2. Scan for Codes

Use an OBD-II scanner to read any stored fault codes.
Document the codes for reference and clear them.

3. Inspect Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel.
Check for physical damage or debris obstructing the sensors.
Clean sensors with a soft cloth if dirty and reconnect any loose connectors.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the brake fluid is at the recommended level. If low, top off with the appropriate brake fluid (usually DOT 3 or DOT 4).

5. Test Traction Control Switch

Locate the traction control switch (usually on the dashboard).
Use a multimeter to test the switch for continuity when pressed.
Replace the switch if it does not operate correctly.

6. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors leading to the ABS module and traction control system.
Repair any damaged wires or connectors as necessary.

7. Tire Inspection

Check all tires for proper inflation and tread depth.
Inflate tires to the manufacturer's recommended pressure if necessary.
Replace any tires that are excessively worn or damaged.
