list systems, troubleshooting roadmaps, fault symptoms, summary troubleshooting
procedures, and system support diagrams. The following breakdown tells you what
is in each column.
a. System Column. This column gives a list of systems on the truck for which
troubleshooting can be done at the operator's maintenance level.
b. Troubleshooting Roadmaps Column. This column tells you where to find
the troubleshooting roadmap for each listed system. These roadmaps are given in
c. Fault Symptom Index Column. This column tells you where to find the
troubleshooting fault symptom index for each listed system. Fault symptom indexes
are given in chapter 6.
d. Summary Troubleshooting Procedures Column. Summary troubleshooting
procedures are not needed at this level of maintenance because they would be the
same as the detailed troubleshooting procedures, so this column is not used. The
detailed troubleshooting procedures found by using the fault symptom indexes will
get you to the cause of the trouble quickly.
e. System Support Diagrams Column. The detailed troubleshooting procedures
in this volume will give you all the information you need to find the bad part or problem
with the truck. So, because support diagrams are not needed, this column is not used.
