Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to ensure safety during repair.
Allow the vehicle to cool if it has been recently driven.

2. Check and Replace ABS Fuse

Tools Required: Fuse puller or pliers.
Locate the fuse box and identify the ABS fuse based on the owner's manual.
Remove the fuse and inspect for continuity. Replace it if it is blown.

3. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solution, and a soft brush.
Lift the vehicle and remove the wheel to access the wheel speed sensors.
Clean the sensors and mounting area with a cleaning solution and soft brush.
Reinstall the wheel and lower the vehicle.

4. Check Brake Fluid Level

Tools Required: Clean rag for wiping and funnel if needed.
Open the master cylinder reservoir cap.
Inspect the brake fluid level; it should be between the minimum and maximum marks.
If low, add the recommended brake fluid type as specified in the owner's manual.

5. Inspect Wiring and Connectors

Tools Required: Multimeter.
Follow the wiring harness from the ABS module to the wheel speed sensors.
Look for any frayed wires or loose connections.
Use the multimeter to test continuity in the wires.

6. Test ABS Functionality

Tools Required: OBD-II scanner capable of ABS diagnostics.
Reconnect the battery and start the vehicle.
Use the OBD-II scanner to perform a test of the ABS system and clear any fault codes.
Observe if the ABS warning light turns off after the test.
