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.
DIX_FIXOpenCircuit
Tip Strip: Injector open-circuit fault
Detail: Indicates that the associated DI Driver channel cannot drive current above 1.5A at any point within the
injection command. This is a non-critical fault and cannot be cleared. This fault does not interfere with injector
channel operation. The fault will be automatically cleared upon the next injection command during which 1.5A is
reached.
DIX_HighVoltageLimitFault
Tip Strip: Internal boost power supply over-voltage fault
Detail: Indicates that the high-voltage supply has exceeded 195V. This can occur if the high-voltage supply is not
used at all during injection events, while energy is recovered from the injector to the internal boost supply during
BackBoostTime . This can also occur if an external high-voltage supply is used and is configured for outputting more
than 195V. Such a condition is strongly discouraged because the components of the DI Driver module are only rated
for 200V. This is a critical fault and will shut down the internal boost power supply and all injector channels.
DIX_LowVoltageDriverFault
Tip Strip: Low voltage driver circuit fault
