Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Faulty Wheel Speed Sensors

Access the Sensors: Raise the vehicle securely on jack stands and remove the wheels to gain access to the wheel speed sensors.
Disconnect Electrical Connector: Carefully unplug the electrical connector from the faulty wheel speed sensor.
Remove the Sensor: Unscrew the sensor using the appropriate socket or wrench. Note the orientation for reinstalling the new sensor.
Install New Sensor: Position the new sensor in place and secure it with the original hardware.
Reconnect Electrical Connector: Plug the electrical connector back into the new sensor.

3. Repair or Replace ABS Module

Locate the ABS Module: Find the ABS module, usually mounted near the master cylinder.
Disconnect Wiring Harness: Carefully unclip and unplug the wiring harness from the ABS module.
Remove the Module: Unscrew the mounting bolts that hold the ABS module in place and remove it.
Install New ABS Module: Place the new ABS module in the same position and secure it with the original bolts. Torque to manufacturer specifications.
Reconnect Wiring Harness: Plug the wiring harness back into the new ABS module.

4. Reconnect Battery and Test

Reconnect the Battery: Ensure all tools are removed from the engine bay, then reconnect the battery.
Scan for Codes Again: Use the OBD-II scanner to check for any remaining codes.
Test Drive: Take the vehicle for a short test drive to ensure that the ABS light does not reappear and the system functions correctly.
