Diagnostics
The i5601E digital display indicates if certain malfunctions occur. The system
also stores certain DTC (Diagnostic Trouble Codes) for reference. These codes
will help you or a technician to determine which subsystem has malfunctioned.
Display and record all Trouble Codes so you can relay them to the technician.
A listing of possible Diagnostic Trouble Codes are in Appendix E.
There are also diagnostic lights built into the Electronic Control System to
assist in troubleshooting. The shift/throttle control head will flash to indicate
improper operation (see the section on the control head function).
There is an i8350 or i8355 Engine Control Unit (ECU) mounted in the engine
room. On the ECU module are three LED indicator lights which normally
flash to acknowledge proper operation. When the ignition switch is “ON”
and/or the engine is running, the three LED indicators will flash at various
rates to indicate the following:
Operation
•
ENGINE CONTROL UNIT STATUS BLUE
•
J1939 CANB us OPERATION YELLOW
•
NMEA2000
®
CANB us OPERATION GREEN
If any of these are not flashing, consult your dealer.

Critical Alarms
Continuous flashing
both lights on either side of the
control indicates a Critical Alarm . System will do a “Safe
Shut Down,” and
must be serviced before further use
.
When a critical alarm occurs, the system will automatically
go to the selected “Fail Safe Response” mode. The system
MUST
be shut down and restarted for most critical alarms.
Some functions may operate for a time after restart. See
display on Control Unit to determine cause of alarm.
If the alarm is caused by the Throttle Actuator hitting
“Stop” - Wide Open Throttle (WOT) - the alarm will go
away when the throttle is pulled back.
However, as with
ALL Critical Alarms, the system must be serviced before
further use.
non-Critical Alarms
Intermittent flashing
of both lights on either side the
control (five seconds flash, normal for fifteen seconds, then
repeating), indicates a Non-Critical Alarm . Acknowledge
by a power up cycle. Continue to operate and have the
system checked as soon as possible.
