This indicates a short or open
circuit on the CAN communications
lines between the Logic/Display
Module and the Junction/Diagnostic
Module.
25.6 Diagnostic Warning screens, in order of display priority:
This screen indicates that the main
current loop (retard timing control)
has deviated outside the limits of
2mA and 22mA. The current loop
follows the configured curve which
is specified from 0-25mA. This
diagnostic is active only if the
current loop retard is on.
This screen indicates that the firing
pattern configuration data saved in
EEPROM memory is incorrect or
incomplete. The EEPROM memory
must be reprogrammed.
This screen indicates that the
ignition processor detected a
communication interruption
between itself and the display
processor in the Junction/Diagnostic
Module.
This could indicate a wiring fault or
a failure inside the Logic/Display
Module.
This screen indicates that the
diagnostics have identified no current
draw on the master coil primary of
cylinders 1R and 2R.
This normally indicates faulty
wiring or a failed coil.
NOTE: Diagnostic FAULTS will
supersede diagnostic WARNINGS.
