2. Address Error Codes

Reconnect the OBD-II scanner and retrieve any error codes.
Note the codes and research any specific repair procedures associated with them.
Clear the codes and perform a test drive to see if they reappear.

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench.
Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor connector and remove the sensor using the socket set.
Inspect the sensor and the tone ring for damage or debris.
If damaged, install a new wheel speed sensor, securing it with the correct torque specifications.

4. Check and Repair ABS Module

Tools Required: Multimeter, socket set.
Locate the ABS module, usually near the master cylinder.
Disconnect the electrical connector and perform continuity tests with a multimeter.
If the module is faulty, replace it with a new unit according to the manufacturer’s specifications.
