Solution

1. Preparation

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

2. Retrieve and Address Error Codes

Sub-steps:
- Connect the OBD-II scanner to the vehicle's diagnostic port.
- Retrieve and note all stored error codes.
- Address the specific codes indicated, such as replacing faulty sensors.

3. Inspect and Clean Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors on each wheel hub.
- Unplug the wiring harness from each sensor.
- Remove the sensor using a socket set (usually 10mm).
- Clean the sensor and mounting area with brake cleaner.
- Reinstall and reconnect the sensor.

4. Check Brake Fluid Level

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level against the minimum and maximum indicators.
- If low, refill with the recommended brake fluid (DOT 3 or DOT 4).
- Recheck for leaks around the brake lines.

5. Test Traction Control Switch

Sub-steps:
- Locate the traction control switch on the dashboard.
- Disconnect the switch and test for continuity using a multimeter.
- If the switch is faulty, replace it with a new part.

6. Reconnect Battery and Clear Codes

Sub-steps:
- Reconnect the battery terminal securely.
