Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is in the OFF position.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors (if faulty)

Tools Required: Socket set, Torque wrench, Multimeter
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel corresponding to the faulty sensor (as indicated by DTCs).
3. Disconnect the wheel speed sensor connector located on the wheel hub.
4. Remove the sensor from its mounting location.
5. Install the new wheel speed sensor in reverse order of removal.
6. Torque the sensor mounting bolt to the manufacturer’s specification (consult service manual for exact value).
7. Reconnect the sensor connector and reinstall the wheel.

3. Check and Replace Brake Fluid (if necessary)

Tools Required: Brake fluid, Brake bleeder kit
Sub-steps:
1. Inspect the brake fluid reservoir level; if low, top it off with the recommended brake fluid type (consult the owner's manual).
2. If the fluid appears contaminated, perform a brake fluid flush using a brake bleeder kit.
3. Bleed the brakes until clean, new fluid flows from each brake caliper.

4. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the negative battery terminal securely.
2. Use the OBD-II scanner to clear any stored DTCs.
3. Start the vehicle to check if the traction control light remains off.
