Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the ignition is off.
Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, brake cleaner.

2. Inspect and Replace Wheel Speed Sensors

Lift the vehicle and secure it with jack stands.
Remove the wheel corresponding to the ABS warning.
Locate the ABS wheel speed sensor on the hub assembly.
Disconnect the electrical connector from the sensor.
Remove the mounting bolt(s) securing the sensor and take out the sensor.
Inspect the sensor for damage; if damaged, replace it with a new one.
Reinstall the new sensor, ensuring it is properly seated and secured.

3. Check and Refill Brake Fluid

Locate the master cylinder reservoir under the hood.
Remove the cap and check the fluid level; if low, top it off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
If the fluid is contaminated or old, perform a brake fluid flush.

4. Clear Error Codes

Use the OBD-II scanner to clear any stored ABS error codes.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner's instructions to erase codes and reset the ABS system.

5. Reassemble and Test Drive

Reassemble any components or wheel parts removed during the process.
Lower the vehicle and ensure all tools are removed from the engine bay.
Conduct a test drive to verify that the ABS light remains off and the system functions properly.
