CAN Bus Diagnostic Screen
See Figure 3-31 for following procedure.
The CAN bus diagnostic screen is for technicians. The
screen displays CAN bus packet and node information,
engine status, history status, and boom status.
The CAN Bus screen operates on two levels:
Level 1 — Packet number box highlighted blue.
Level 2 — Packet number box highlighted red.
Packet Information Boxes
The first box of the top row the example screen contains the
Packet Number. Enter the desired packet number by using
Select buttons.
Packet Type (DO, DI, AO, AI, ENC, or PWM) is displayed on
top middle data box.
The associated Node (3) is indicated in top right data box.
In the box in the second row, the content of the packet is
displayed in eight “banks.” Cross-reference the number that
appears in a bank to Table 3-8
to determine the identity or
status of the associated input or output.
Each input or output is assigned a number (identifier) in the
binary system (powers of two):
- The identifiers of all inputs/outputs that are ON
(active) for each bank are added for a total of 0–255.
- The number displayed for each bank is the sum of
all identifiers that are ON in that bank.
- Each possible ON/OFF combination per bank has a
unique total.
Many packets are not easily interpreted by other than factory
technical personnel and their content is not discussed in this
publication.
Also see Using the CAN Bus Screen to Troubleshoot a
Digital Output Fault on page 3-37.
Engine Node Status Box

for factory use only. The number displayed should be under
64.
