Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Clean ABS Sensors

Tools Required: Brush, cleaning solution, multimeter
Remove the wheel covering the ABS sensor (if applicable).
Clean the ABS sensor and surrounding area with a brush and cleaning solution to remove any dirt or debris.
Reconnect the sensor if it was disconnected during cleaning.

3. Replace ABS Sensor (if necessary)

Tools Required: Socket set, torque wrench
Locate the ABS sensor at the wheel hub assembly.
Remove the retaining bolts using a socket set and carefully pull out the sensor from its housing.
Install the new ABS sensor by inserting it into the housing and securing it with the retaining bolts. Torque the bolts to the manufacturer’s specifications (generally around 7-10 ft-lbs).

4. Reassemble and Reconnect

Reinstall the wheel and tighten lug nuts to the manufacturer's specifications.
Reconnect the battery.
Clear any fault codes from the ABS system using the OBD-II scanner.

5. Final Check

Start the vehicle and check that the ABS warning light is off.
Perform a test drive to confirm proper braking function and ensure the ABS is operating correctly.
