Question
What challenges exist in diagnosing firmware encryption verification failures?
Answer
They involve invalid digital signatures or key mismatches preventing ECU operation.
Explain
Modern ECUs verify firmware signatures during boot to prevent tampering. CHEPQ diagnostic tools check signature validation logs, verify key integrity, and diagnose failures caused by corrupted firmware, invalid keys, or unauthorized modifications. This ensures only authentic firmware runs on the ECU, maintaining system security and functionality.
