Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter.
Sub-steps:
1. Lift the vehicle using a jack and support it with jack stands.
2. Remove the wheel corresponding to the sensor under inspection.
3. Locate the wheel speed sensor and disconnect its electrical connector.
4. Remove the retaining bolt securing the sensor and extract the sensor from its position.
5. Test the old sensor with a multimeter; if it shows no continuity, replace it with a new one.
6. Install the new sensor, securing it with the bolt and reconnect the electrical connector.

3. Inspect and Clear ABS Module Faults

Tools Required: OBD-II scanner.
Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to check for ABS-related trouble codes.
3. If codes are present, note them and clear the codes from the system.
4. Test drive the vehicle to see if the traction control light reappears.

4. Check Brake Fluid Level

Tools Required: None.
Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, add the appropriate brake fluid type (usually DOT 4).
3. Close the reservoir cap securely.
