Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the ignition is off.
Tools Required: OBD-II scanner, multimeter, socket set, cleaning brushes.

2. Diagnose and Repair Wheel Speed Sensors

Sub-steps:
1. Remove the wheel and tire to access the wheel speed sensor.
2. Disconnect the electrical connector from the sensor.
3. Use a multimeter to test the sensor's resistance; compare the reading to manufacturer specifications.
4. If faulty, replace the wheel speed sensor with a new one, ensuring it is properly aligned and secured.

3. Inspect and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; if low, inspect for leaks in the brake lines or calipers.
3. If leaks are found, repair them before refilling.
4. Add the appropriate type of brake fluid as specified in the owner's manual.

4. Check and Repair ABS Module

Sub-steps:
1. Locate the ABS module; refer to the service manual for specific location details.
2. Inspect the module for any visible damage or loose connections.
3. If necessary, test the module's voltage and ground using a multimeter.
4. Replace the ABS module if it fails the tests.

5. Test Traction Control Switch

Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Remove the switch and use a multimeter to check for continuity when pressed.
3. Replace the switch if it shows no continuity or is otherwise malfunctioning.
