Diagnostic Information Display

The 17FM558 Diagnostic Information Display (DID)
(Figure 2-2) is located in the cab, behind the passenger
seat. The display provides a means of communica-
tions with the TCI by service personnel. Information
from the PSC Aux Inverter is also routed through the
TCI for display on the DID.
The panel has two display lines, each line 40 charac-
ters long. The top line is the "message" line and is used
by the TCI to inform service personnel of the truck
systems and components status.
The bottom display line provides information in addi-
tion to the top line or relates to the keypad, displaying
possible selection options and display functions. The
keypad, located below the display lines is used by
service personnel to direct the activity of the TCI.
The display provides service and status information on
the various truck systems and the propulsion system
by displaying system status information or fault codes
as well as a description of the system status or a
problem on the top display line. Information on the
second display line may change to indicate what func-
tions are available by pressing the [F1] through [F5]
keys.
In addition, the DID panel can be used by to perform
