Detail: The DI driver module maintains an integrator of power supply usage. An internal counter increments
with each internal power supply voltage boost and decrements according to a fixed time interval. If the
integrator winds up to 100 percent, then an overload fault will be set. This is an indication that the module
temperature would soon rise beyond its maximum operating temperature if not stopped. The
temperature fault may be tripped before the overload fault, depending on the actual conditions.
DIX_PSChargeFault
Tip Strip: DI Driver internal boost power supply charging fault
Detail: Indicates that the internal boost power supply is not able to increase the voltage within 255 boost
pulses. This is a critical fault and will shut down the internal boost power supply and all injector channels.
DIX_PSOverloadFault
Tip Strip: Internal boost power supply charging fault
Detail: Indicates that the internal boost power supply is overloaded and cannot keep up with the demand,
otherwise it will overheat. This is a critical fault and will shut down the internal boost power supply and all
injector channels.
DIX_ShortCircuitFault
Tip Strip: Injector short-circuit fault
Detail: Indicates that the current to one of the DI Driver module channels exceeded 40A and is likely
experiencing a short circuit condition. This is a critical fault and will shut down the internal boost power
supply and all injector channels.
DIX_ModuleTempFault
Tip Strip: Module over-temperature fault (80C)
Detail: Indicates that the internal DI Driver module temperature has exceeded 80 C. This is a critical fault and
will shut down the internal boost power supply and all injector channels.
DIX_HighVoltageDriverFault
Tip Strip: High voltage driver circuit fault
Detail: Indicates that the high-voltage, high-side FET is overloaded. This fault is often caused by a short
circuit condition during high-voltage drive phases. This is a critical fault and will shut down the internal boost
power supply and all injector channels.
