Question
How does immobilizer synchronization reset resolve no-start conditions?
Answer
It re-establishes secure communication between ECU and key modules.
Explain
When ECU and immobilizer modules lose synchronization, engine start authorization fails. CHEPQ immobilizer tools perform controlled resynchronization, updating cryptographic tokens and key IDs, restoring communication integrity without module replacement, thus avoiding costly repairs while maintaining anti-theft security.
