Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Use a multimeter to check the sensor’s resistance (should typically be around 1,000-2,000 ohms).
If the sensor is faulty, replace it with a new one and reconnect.

3. Check Brake Fluid Level

Locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top up with the recommended brake fluid (DOT 3 or DOT 4).
Reconnect the battery terminal.

4. Inspect the ABS Module

Tools Required: OBD-II scanner
Reconnect the battery and power on the vehicle.
Use the scanner to check for any ABS-related error codes.
If codes are present, follow the specific troubleshooting guidelines for those codes.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Inspect the switch for physical damage or wear.
Use a multimeter to check for continuity when the switch is pressed. Replace if defective.

6. Reassemble and Clear Codes

Reinstall any components removed during the inspection.
Clear any error codes from the OBD-II system with the scanner.
Conduct a test drive to ensure the traction control light remains off.
