Locate the ABS module, which is typically mounted near the master cylinder.
Remove any covers or shields obstructing access to the ABS module.
Disconnect the electrical connectors from the ABS module by pressing the release tab and pulling the connector out.
Unbolt the ABS module from its mounting bracket (typically 2-4 bolts) using a socket set. Note the torque specifications for reinstallation.
Carefully remove the ABS module from the vehicle.

3. Inspect and Replace

If the module is faulty, replace it with a new or remanufactured ABS module that is compatible with the 2019-2024 Toyota Corolla E210.
Ensure the new module has the correct part number and specifications.

4. Reinstall the ABS Module

Position the new ABS module in place and secure it with the previously removed bolts. Use the torque wrench to tighten to the manufacturer's specifications.
Reconnect all electrical connectors, ensuring they click into place securely.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check the dashboard for any warning lights.
Perform a brake system self-diagnosis using a scan tool to verify that the ABS module is functioning correctly and no error codes remain.
