System check
Press and hold the SELECT/RESET control switch to select SYSTEM
CHECK when HOLD RESET FOR SYSTEM CHECK is displayed in the
message center. Selecting this function from the INFO MENU causes the
message center to cycle through each of the systems being monitored.
For each of the monitored systems, the message center will indicate
either an OK message or a warning message for two seconds. Pressing
the SELECT/RESET control switch cycles the message center through
each of the systems being monitored.
The sequence of the system check report and how it appears in the
message center is as follows:
1. ENGINE HOURS
2. CHARGING SYSTEM
3. AIR FILTER (Diesel engine only)
4. DOOR AJAR
5. BRAKE SYSTEM
6. FUEL LEVEL
7. TRAILER DISCONNECTED (if equipped)
System warnings
System warnings alert you to possible problems or malfunctions in your
vehicle’s operating systems.
In the event of a multiple warning situation, the message center will
cycle the display to show all warnings by displaying each one for 4
seconds.
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
SELECT/RESET control and clearing the warning message.
Warning messages that have been reset are divided into two categories:
• They will reappear on the display ten minutes from the reset.
• They will not reappear until an ignition OFF-RUN cycle has been
completed.
This acts as a reminder that these warning conditions still exist within
the vehicle.
