Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, cleaning supplies, and safety gloves.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Address Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Locate the wheel speed sensors near each wheel hub.
3. Disconnect the wiring harness from the sensors.
4. Remove the sensors using the appropriate socket and inspect for dirt or damage.
5. Clean the sensors with a soft cloth or brake cleaner; replace if damaged.
6. Reinstall the sensors and reconnect the wiring harness.

3. Inspect Brake System

Sub-steps:
1. Check brake fluid level in the master cylinder reservoir; refill with manufacturer-recommended brake fluid if low.
2. Inspect brake pads and rotors for wear; replace if needed.
3. Ensure brake lines are intact without leaks.

4. Verify ABS Module Functionality

Sub-steps:
1. Reconnect the OBD-II scanner and check for any ABS or traction control-related error codes.
2. Clear any fault codes and perform a test drive to see if the issue persists.
3. If the warning lights remain, consider replacing the ABS module.

5. Wiring and Connector Inspection

Sub-steps:
1. Inspect the wiring harness connected to the wheel speed sensors and ABS module for fraying or corrosion.
2. Use a multimeter to test for continuity in the wiring.
3. Repair or replace any damaged wiring or connectors.
