Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove any debris or dirt from the sensor area with a clean cloth.
3. Check the wiring harness for any fraying or disconnections.
4. Reconnect any loose wires and secure them in place.

3. Replace Faulty Wheel Speed Sensor (if needed)

Tools Required: Socket set, torque wrench
Sub-steps:
1. Use a socket set to remove the faulty wheel speed sensor from the hub.
2. Install the new wheel speed sensor and torque it to the manufacturer’s specifications (typically around 10-15 Nm).
3. Reconnect the wiring harness to the sensor.

4. Check and Replace ABS Fuse (if necessary)

Sub-steps:
1. Locate the fuse box and find the corresponding ABS fuse.
2. Remove the fuse and inspect it for continuity.
3. Replace with a new fuse of the same amperage if blown.

5. Reconnect Battery and Reset ABS System

Sub-steps:
1. Reconnect the battery terminals and ensure they are tight.
2. Use the OBD-II scanner to clear any error codes from the ABS system.
3. Turn the ignition on without starting the engine to check if the ABS light remains off.
