FAULT CODES
Engine fault codes (active and stored) are generated by the engine ECU and communicated to
the control panel.
ACTIVE FAULT CODES
The control system reads
standard messages to indicate
active fault codes. When a fault
is active the control system
activates a popup fault display
containing a check engine icon,
fault code number (if applicable),
a description of the active fault
and an “Active Codes” alarm
stripe at the bottom of the display.
The control system will activate
the red LED fault indicator above
the digital display.
When an active fault is presented,
the user must acknowledge the
fault by pressing the softkey
indicated. See “Acknowledging
Active Faults” section.
After acknowledging a fault
condition, the system will return
to normal display operation.
The controller will indicate that
an active fault is present by
displaying a “Check Engine” icon
on the main data display. The
system will also display an “Active
Codes” alarm stripe at the bottom of the display.
ACKNOWLEDGING ACTIVE FAULTS
When the control system receives a new fault, the digital display responds by overlaying a fault
pop-up graphic onto the currently active runtime display. This alerts the operator, signaling a
response is needed by the operator. The display above (top) represents an unacknowledged
fault for an oil pressure fault condition. To acknowledge an active fault, press the “Acknowledge”
softkey (middle) button. This will remove the pop-up graphic. The control system will continue to
inform the operator that a fault is active or until the fault is corrected.
Note: If the fault condition is cleared the associated pop-up will be automatically removed.
