When DTC is Displayed
The engine is cranking or running, during Harness Diagnostic Mode Test, at key ON ECU startup process and the

Typically, this means that there is a short to ground or an open in the high-pressure high-pressure fuel pump suction
control valve circuit. The engine will probably not start because the valve is wide open which will cause maximum
pressure which will trip the pressure relief valve on the rail.
