Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, brake fluid, cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental electrical discharge.

2. Check and Replace Fuses

Locate the fuse box (consult owner’s manual for exact location).
Use a fuse puller to remove the ABS fuse.
Inspect the fuse for continuity using a multimeter; replace if blown.
Reinstall the new fuse and reconnect the battery terminal.

3. Inspect and Clean Wheel Speed Sensors

Jack up the vehicle and secure it with jack stands.
Remove the wheel to access the wheel speed sensors.
Clean any debris or dirt from the sensor and the ring it reads.
Check the wiring for any signs of fraying or disconnection.
Reinstall the wheel and lower the vehicle.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check if the brake fluid is at the recommended level (between minimum and maximum).
If low, add the appropriate type of brake fluid as specified in the owner’s manual, then check for leaks.

5. Test ABS Module and Reset Codes

Reconnect the OBD-II scanner and clear any stored ABS codes.
Start the vehicle and check if the ABS light remains illuminated.
If the light is off, perform a test drive to ensure proper ABS function.
