Question
How does immobilizer key transponder encryption algorithm fault diagnosis ensure security?
Answer
It verifies correct encryption of key-transponder communication.
Explain
Encryption algorithm faults compromise immobilizer security. CHEPQ immobilizer tools verify encryption/decryption of transponder data, detect algorithm corruption, and guide module replacement or reflash. This maintains anti-theft protection, preventing unauthorized key cloning.
