Question
How does ECU firmware checksum mismatch diagnosis prevent unstable operation?
Answer
It detects corrupted firmware causing erratic module behavior.
Explain
Checksum mismatch indicates firmware corruption. CHEPQ diagnostic tools compare computed checksums with stored values, detect corruption, and guide firmware reflash. This restores stable ECU operation, preventing drivability issues or system failures.
