In the event that the Engine Control Unit (ECU) senses a problem or a malfunction on the equipment it should trigger an ECU fault code. The ECU fault code is designed to tell us exactly what problem the equipment is experiencing.

ECU fault codes, also known as Diagnostic Trouble Codes (DTC), form part of the On-board Diagnostic (OBD II) system in the specific piece of equipment. These codes provide information as to which systems are malfunctioning. The exact location of the issue, and the direct cause off the underperformance of the engine. Power O2 is equipped to deal with the engine issues.
