Question
How does ECU bootloader security affect firmware update safety?

It protects the ECU from unauthorized or corrupted firmware flashes during updates.
Explain
The bootloader is the initial program that runs ECU firmware updates, ensuring only authenticated and intact software is installed. CHEPQ tools verify digital signatures and integrity checks during flashing, preventing malicious code injection or bricking. This security layer maintains vehicle safety and system stability through controlled firmware management.
