Diagnostic Information Display (DID) Panel
The DID panel (Figure 2-2) is located in the cab
behind the operator's seat. The display provides
service personnel with a means of communicating
with the TCI.
The panel has two display lines. Each line is 40
characters 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
addition 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 which functions are available by pressing
keys [F1] through [F5].
The DID panel can also be used to perform the self-
load test.
