Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set.
Ensure the vehicle is parked on a level surface and the engine is off. Wear safety gloves and goggles.

2. Check ABS Fuse

Sub-steps:
1. Open the fuse box and locate the ABS fuse.
2. Remove the fuse and check for any breaks in the metal strip.
3. If blown, replace it with a fuse of the same amperage.

3. Inspect Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Inspect the sensor and wiring for any signs of damage or corrosion.
4. Clean any debris around the sensor and reconnect the wiring if necessary.

4. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Ensure the fluid level is between the minimum and maximum marks.
3. If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).

5. Reset ABS System

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Navigate to the ABS section and select the option to clear the codes.
3. Turn the ignition off and then back on to check if the ABS light remains off.
