Solution

1. Preparation

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

2. Address Wheel Speed Sensor Issues

Tools Required: Socket set, multimeter
Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel corresponding to the problematic wheel speed sensor.
3. Locate the wheel speed sensor connector and disconnect it.
4. Use a multimeter to check for continuity in the sensor wiring.
5. If the wiring is intact but the sensor is faulty, remove the sensor and replace it with a new one.
6. Reconnect the sensor and ensure all connections are secure.

3. Check ABS Module

Tools Required: OBD-II scanner
Sub-steps:
1. Reconnect the battery terminal.
2. Use the OBD-II scanner to read any ABS-related fault codes.
3. If codes indicate a malfunctioning ABS module, replace the ABS control unit as needed.
4. Clear the fault codes using the scanner and test drive the vehicle.

4. Inspect Brake System

Tools Required: Brake fluid tester, wrench set
Sub-steps:
1. Check brake fluid levels in the master cylinder reservoir.
2. Inspect brake lines for leaks or damage.
3. If fluid levels are low, top up with the manufacturer-recommended brake fluid.
4. Inspect brake pads and rotors for wear and replace if necessary.

5. Verify Traction Control Switch

Tools Required: Multimeter
Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Disconnect the switch connector.
3. Use a multimeter to test for continuity when the switch is activated.
4. Replace the switch if it does not show proper continuity.
