Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect Wheel Speed Sensors

Remove the wheel for access to the wheel speed sensor.
Disconnect the sensor's electrical connector.
Clean the sensor area and inspect for any debris or damage.
Reconnect the sensor and wheel, then torque the lug nuts to the manufacturer's specifications.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the fluid level is between the "MIN" and "MAX" marks.
If low, add the manufacturer-recommended brake fluid.

4. Verify ABS Control Module

Remove any necessary covers to access the ABS control module.
Inspect the wiring and connectors for corrosion or damage.
If damaged, replace the ABS control module. Follow the manufacturer's guidelines for installation.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test for continuity when the switch is pressed.
If the switch is faulty, replace it with a new one.

6. Tire Inspection

Visually inspect all tires for uneven wear or damage.
Measure tire pressure and adjust to the manufacturer's recommended PSI.
Replace any significantly worn or damaged tires.
