This screen indicates that the
Logic/Display Module has detected
an interruption in the internal
communication between the display
processor and ignition processor.
This could indicate a wiring fault or
failure inside the Logic/Display Module.
This screen indicates that the Logic/
Display Module has lost communication
with the Junction/Diagnostic Module.
This could indicate a wiring fault
between the Logic/Display Module and
the Junction/Diagnostic Module or a
faulty diagnostic processor inside the
Junction/Diagnostic Module.
This screen indicates that the auxili-
ary current loop (spark number
control) has deviated outside the
limits of 2mA and 22mA. The current
loop follows the configured curve
which is specified from 4-20mA.
This diagnostic is active only if the
4-20mA spark select map is on.
This screen indicates that the
voltage detected at the junction
module is not within the acceptable
range for the requested spark
number. This could indicate loose
wiring between the Logic/Display
Module and Junction/Diagnostic Module
or a faulty connector.
This indicates that the mapping
between the spark diagnostics and
the actual engine firing order is
incorrect and needs to be updated.
This indicates that the voltage
supplied to the left Output Module
(rails 1 and 2) has deviated outside
of the normal operating range. This
can result from poor wiring, an
inadequate power supply, or a
discharged/weak supply battery.
