Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Address Fault Codes

Sub-steps:
1. Connect the OBD-II scanner and retrieve any stored codes.
2. Document the codes and research their meanings.
3. Clear the codes and test drive the vehicle to see if they reappear.

3. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solution, soft brush
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensors.
3. Disconnect the sensor electrical connector.
4. Remove the sensor from its mounting bracket.
5. Clean the sensor and its mounting area using a soft brush and cleaning solution.
6. Reinstall the sensor, ensuring it is correctly positioned.

4. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level against the minimum and maximum marks.
3. If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
4. Inspect for any leaks in the brake system.

5. Inspect TCS Switch

Sub-steps:
1. Locate the TCS switch on the dashboard.
2. Test the switch functionality using a multimeter.
3. If faulty, disconnect the switch and replace it with a new one.

6. Verify Wiring and Connectors

Sub-steps:
1. Visually inspect wiring and connectors leading to the TCS components.
2. Look for signs of wear, corrosion, or loose connections.
3. Repair or replace any damaged wiring or connectors as necessary.
