Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Remove the wheel corresponding to the ABS sensor showing a fault.
Disconnect the wheel speed sensor connector.
Use a multimeter to test the sensor for proper resistance (consult service manual for specifications).
If the sensor is faulty, remove the mounting bolt and replace it with a new sensor, securing it to the hub assembly.
Reconnect the sensor and reinstall the wheel.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid tester, funnel.
Locate the brake fluid reservoir and check the fluid level.
If fluid is low or contaminated, siphon out the old fluid and replace it with new, manufacturer-recommended brake fluid.
Bleed the brake system to ensure no air is trapped.

4. Inspect ABS Control Module

Tools Required: OBD-II scanner.
Reconnect the battery and use the OBD-II scanner to clear any codes and reset the ABS system.
Drive the vehicle to check if the ABS light remains off.
