Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, brake cleaner
Remove the wheel on the affected corner to access the wheel speed sensor.
Clean the sensor and surrounding area with brake cleaner to remove any debris.
Reinstall the wheel and repeat for other corners as necessary.

3. Replace Faulty ABS Wheel Speed Sensor

Tools Required: Socket set, torque wrench
If the wheel speed sensor is faulty, disconnect the wiring harness and unbolt the sensor from its mounting location.
Install the new ABS wheel speed sensor, ensuring it is properly seated.
Torque the sensor to manufacturer specifications (typically around 8-10 lb-ft).
Reconnect the wiring harness and reinstall the wheel.

4. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid reservoir for proper fluid level.
If low, add the appropriate brake fluid (typically DOT 3 or DOT 4) to the fill line.

5. Clear Error Codes

Tools Required: OBD-II scanner
Reconnect the negative battery terminal.
Start the vehicle and use the OBD-II scanner to clear any ABS-related error codes.
Monitor the ABS light to ensure it does not illuminate again during normal operation.
