Code P1695 Hyundai Description

The P1695 code for Hyundai vehicles indicates an Immobilizer EEPROM Error. The immobilizer system is a security feature in modern vehicles that prevents the engine from starting without the correct key. The EEPROM (Electrically Erasable Programmable Read-Only Memory) is a memory chip that stores important data for the immobilizer system, such as key codes and authentication information.
