P060A 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.
Is it safe to drive with P060A?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
