Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to avoid electrical shorts.
Ensure the vehicle is on a level surface and secure with jack stands if needed.

2. Inspect and Repair Wheel Speed Sensors

Sub-step 1: Remove the wheel corresponding to the sensor that is faulty (as indicated by the diagnostic steps).
- Tools Required: Jack, jack stands, lug wrench.
Sub-step 2: Locate the wheel speed sensor and disconnect the electrical connector.
Sub-step 3: Remove the retaining bolts of the wheel speed sensor using a socket set.
Sub-step 4: Carefully pull out the wheel speed sensor from its mounting location.
Sub-step 5: Inspect the old sensor for physical damage and check the connector for corrosion.
Sub-step 6: If the sensor is faulty, install a new wheel speed sensor in reverse order of removal, ensuring it is securely fastened.

3. Check and Repair Wiring

Sub-step 1: Inspect the wiring harness connected to the wheel speed sensor for any frays or exposed wires.
Sub-step 2: Repair or replace any damaged wiring or connectors as necessary.
Sub-step 3: Use electrical tape or heat-shrink tubing for insulation and protection.

4. Test the ABS System

Sub-step 1: Reconnect the battery and clear any stored trouble codes using the OBD-II scanner.
Sub-step 2: Start the vehicle and perform a test drive to check if the ABS light remains off and the system functions properly.
Sub-step 3: Monitor the brake pedal feel and ensure the ABS activates during hard braking.
