Step 2: Clean the brake components using brake cleaner.
Step 3: Replace any worn components, ensuring that the EPB mechanism is free of debris.

5. Error Messages on the Display

Step 1: Use the OBD-II scanner to identify any specific error codes related to the EPB.
Step 2: Address the specific issues indicated by the codes (e.g., recalibrating the system or replacing faulty components).
Step 3: Clear the error messages and test the system operation.

Final Steps

Test Drive: After repairs, conduct a test drive to ensure the parking brake functions correctly under various conditions.
Recheck for DTCs: After the test drive, check again for any new or persistent error codes.
