Internal Control Module Monitoring Processor Performance
Modern ECUs have a separate watchdog or monitoring processor that supervises the main processor. This processor reports a self-diagnosis fault - typically a watchdog event, ROM/RAM mismatch, or check-sum error in its monitor section. The ECU runs in a safety-fallback mode until repair.
