Question
How does ECU watchdog timer functionality prevent system failures?
Answer
It monitors ECU processes and triggers safe modes on faults.
Explain
The watchdog timer supervises ECU software execution, resetting or switching to fallback modes if critical tasks hang or fail. CHEPQ diagnostic tools can check watchdog status and log faults, allowing technicians to diagnose intermittent hangs or firmware bugs that might cause sudden ECU shutdowns or limp-home modes, ensuring system reliability.
