Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts during repair.

2. Replace Blown Fuse

Locate the ABS fuse in the fuse box.
Remove the blown fuse using a fuse puller or pliers.
Replace it with a new fuse of the same amperage.
Reconnect the battery and check if the ABS light is still on.

3. Repair or Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Raise the vehicle safely with jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor's electrical connector and inspect for corrosion or damage.
Test the sensor with a multimeter; if it is faulty, replace it.
Reinstall the new sensor, ensuring it is properly secured and reconnected.

4. Brake Fluid Level Check

Locate the brake fluid reservoir.
Inspect the fluid level; if low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
Recheck the ABS light status after refilling.

5. Inspect ABS Control Module

If all previous steps fail, remove the ABS control module.
Inspect for any visible damage or corrosion on connectors.
If necessary, replace the ABS control module and ensure it is correctly programmed to the vehicle.
