Modern vehicles are controlled by highly advanced electronic systems. At the center of everything is the Engine Control Unit (ECU) — the electronic brain responsible for managing engine performance, emissions, fuel efficiency, and component protection. When something in this chain does not behave as expected, the ECU stores a DTC (Diagnostic Trouble Code) and may activate limp mode , reducing engine power to protect the vehicle. Understanding why this happens is essential
