Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down if it has been running.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Remove the wheel corresponding to the faulty sensor.
Disconnect the wheel speed sensor connector and unbolt the sensor.
Clean the mounting area and install the new wheel speed sensor. Torque to manufacturer's specification.
Reconnect the wheel speed sensor connector.
Repeat for each wheel speed sensor if multiple sensors are faulty.

3. Repair or Replace ABS Module

Tools Required: Socket set, torque wrench, brake line tool
Remove the ABS module mounting bolts using a socket set.
Disconnect the electrical connectors from the ABS module.
If the module is faulty, replace it with a new unit. Otherwise, repair any identified issues.
Reconnect the electrical connectors and reinstall the ABS module, torquing bolts to the specified value.
Reconnect the negative battery terminal.

4. Clear DTCs and Test System

Use the OBD-II scanner to clear any stored DTCs.
Test drive the vehicle to ensure the ABS warning light is off and the system is functioning properly.
