Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery cable to avoid electrical shocks.

2. Address ABS Sensor Issues

Inspect and Clean Sensors:
- Remove the wheel(s) to access the ABS sensors.
- Clean the sensor area with brake cleaner to remove any debris.
Reconnect or Replace Sensors:
- Check the wiring harness and connectors for damage.
- If damaged, replace the ABS sensor with a new part according to manufacturer specifications.

3. Check and Replace Fuses

Locate the Fuse Box:
- Identify the location of the fuse box (refer to the owner's manual).
Inspect the ABS Fuse:
- Remove the ABS fuse and check for continuity using a multimeter.
- If blown, replace with the same amperage fuse (consult owner's manual for specifications).

4. Brake Fluid Maintenance

Check Brake Fluid Level:
- Inspect the brake fluid reservoir; ensure it is filled to the recommended level.
Flush and Replace Brake Fluid:
- If the fluid is contaminated or dark, perform a brake fluid flush using the manufacturer's recommended fluid.

5. Reassemble and Test

Reinstall Components:
- Reattach any components that were removed for access.
- Reconnect the negative battery cable.
Test the System:
- Start the vehicle and check if the ABS light is still illuminated.
- Take the vehicle for a short test drive to verify ABS functionality.
