Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Left Front Wheel Speed Sensor

Tools Required: Socket set, multimeter, torque wrench, wire connectors, dielectric grease.
Sub-steps:
1. Remove the wheel for better access to the wheel speed sensor.
2. Locate the left front wheel speed sensor attached to the wheel hub.
3. Unplug the connector from the sensor and inspect for corrosion or damage.
4. Remove the mounting bolt(s) securing the sensor and carefully pull it out.
5. Install the new wheel speed sensor by reversing the removal steps, ensuring it is securely fastened.
6. Apply dielectric grease to the connector and reconnect it.

3. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and allow it to run for a few minutes.
Check for any remaining error codes using the OBD-II scanner.
Test drive the vehicle to ensure the ABS and traction control lights are extinguished.
