The error code, ATC 000630.02, is triggered when the control unit detects an error in the EEPROM (Electrically Erasable Programmable Read-Only Memory). This type of error can indicate issues with data integrity or problems in storing and retrieving configuration settings essential for the equipment’s operation. EEPROM errors can be caused by hardware failure, data corruption,…
