Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a flat surface and securely supported (jack stands if needed).
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove any dirt or debris from the sensor area using a soft cloth.
3. Check the sensor connectors for corrosion and clean if necessary.
4. Reconnect the sensors securely.

3. Check ABS Module and Wiring

Sub-steps:
1. Access the ABS module, typically located near the master cylinder.
2. Inspect the wiring harness for any signs of wear, fraying, or disconnection.
3. Use a multimeter to test continuity in the wiring.
4. Repair or replace any damaged wiring as required.

4. Brake Fluid Level Check

Sub-steps:
1. Locate the brake fluid reservoir.
2. Check the fluid level; it should be at the "full" mark.
3. If low, top off with the manufacturer-recommended brake fluid.
4. Inspect for any signs of leaks around brake lines and calipers.

5. System Reset

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any diagnostic trouble codes.
3. Start the vehicle and allow it to idle for a few minutes.
4. Take the vehicle for a short test drive to verify if the warning lights reappear.
