Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the vehicle to cool if it has been running.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the wheel speed sensors at each wheel assembly.
3. Clean any debris or dirt from the sensors and connectors using a wire brush and electrical contact cleaner.
4. Ensure the sensors are securely attached and the wiring is intact.

Tools Required: Jack, jack stands, wire brush, electrical contact cleaner.

3. Check and Replace Faulty Components

Sub-steps:
1. If error codes indicate a specific wheel speed sensor failure, remove the sensor from the wheel assembly.
2. Install the new wheel speed sensor, ensuring it is properly seated and tightened.
3. If the ABS module is found to be faulty, remove it from its mounting point and disconnect the electrical connectors.
4. Install the new ABS module and reconnect all wiring securely.

Tools Required: Socket set, torque wrench.

4. Test Traction Control System

Sub-steps:
1. Reconnect the battery and start the vehicle.
2. Drive the vehicle at low speeds and test the traction control system by accelerating on a slippery surface.
3. Monitor the dashboard for any warning lights during the test.

Tools Required: OBD-II scanner for final checks.
