Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Retrieve and Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve ABS-related error codes and note them.
Clear the codes and check if the ABS light returns after a short drive.

3. Inspect and Clean ABS Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area using a clean cloth.
If necessary, disconnect the sensor wiring and inspect the connectors for damage.
Reconnect the sensors securely after cleaning.

4. Replace Faulty Components

If error codes indicate a faulty ABS sensor, remove the sensor using a socket set.
Install the new ABS sensor by reversing the removal process, ensuring it is properly aligned.
Torque the sensor to the manufacturer's specifications (typically around 8-10 Nm).

5. Test the ABS System

Reconnect the negative battery terminal.
Start the vehicle and conduct a test drive to ensure the ABS light does not return.
Test the braking system at low speeds to confirm proper operation.
