Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdrivers.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Inspect ABS Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the ABS sensor.
3. Check the sensor for physical damage and ensure it is securely mounted.
4. Clean the sensor and surrounding area to remove debris.
5. Reinstall the wheel and lower the vehicle.

3. Check ABS Fuse

Sub-steps:
1. Locate the fuse box (refer to owner's manual for location).
2. Remove the cover and locate the ABS fuse.
3. Inspect the fuse for continuity; replace it if blown.
4. Reinstall the fuse box cover.

4. Inspect Wiring and Connectors

Sub-steps:
1. Visually inspect the wiring harness leading to the ABS module and sensors.
2. Look for any signs of fraying, corrosion, or loose connections.
3. Repair or replace damaged wiring as necessary.

5. Test Brake Pedal Position Sensor

Sub-steps:
1. Locate the brake pedal position sensor, usually mounted near the brake pedal.
