CHAPTER 1

GENERAL INFORMATION

1-1. SCOPE. This volume shows you how to do troubleshooting at the direct supportlevel of maintenance. The amount of troubleshooting you can do is based on what theMaintenance Allocation Chart says you can fix. Because of this, the only troublesymptoms you will find here are those that could be caused by faulty things you canfix.

1-2. ORGANIZATION . When you do PMCS, or when you drive the truck and findthat something is wrong, write down what is wrong. Then check the fault symptomindex to see if the trouble (fault symptom) you noted is in the index. If it is, youcan do troubleshooting to find the fault and fix it.

1-3. TROUBLESHOOTING APPROACH. In order to find out what is causing theproblem in the truck, you must use a good approach. A good approach just means away of doing troubleshooting so you can find the problem and not get confused or lost.The following chapter describes how you can use the materials in this volume totroubleshoot with a good approach.

1-1/(1-2 blank)

TM 9-2320-211-34-1

CHAPTER 2

TROUBLESHOOTING APPROACH

2-1. GENERAL APPROACH. This chapter gives you instructions on how to use thetroubleshooting material to help you find and fix the trouble. In every system ofthe truck there can be faults or problems which will cause certain symptoms. Symp-toms can be such things as unusual noise, vibration or even complete failure of asystem. This volume gives information for each system on which you can do trouble-shooting to find faults and fix them. Before you troubleshoot a system, you shouldlook at the troubleshooting indexes which will lead you to the information you need tohelp make your troubleshooting faster and easier. If you follow the instructions theright way, you will find those troubles you can fix. But, if you fix something and thetrouble is still there, it means there is more than one trouble. If this happens, startall over again to find the other trouble.

2-2. TROUBLESHOOTING INDEX. The troubleshooting index, and instructions onhow to use it are in chapter 3. Go to this index first because it tells you where tofind troubleshooting roadmaps, fault symptom indexes, summary troubleshootingcharts and support diagrams for each system.

2-3. TEST EQUIPMENT PROCEDURES INDEX. The test equipment procedures index,and instructions on how to use it are in chapter 4. This index tells you where to findelectrical and mechanical tests which you can use to do your troubleshooting. It alsotells you what equipment you will need to do the tests. If you have a STE/ICE(Simplified Test Equipment/Internal Combustion Engine) Set (NSN 4910-00-124-2554),you may use it, where applicable, to do your troubleshooting. Refer toTM 9-4910-571-12 & P.

2-4. TROUBLESHOOTING ROAD MAPS. Troubleshooting roadmaps for each system arein chapter 5. If the system is made up of subsystems, these subsystems are also onthe roadmap. Under the subsystem is a list of things which are the most likely causesof a fault symptom in that subsystem. If you have enough skill, you can troubleshootthese things on the truck without using the detailed troubleshooting procedures. Soif you know enough about the truck to work on your own, use the roadmap for thesystem with the problem before you check the fault symptom index.

2-5. FAULT SYMPTOM INDEX. Fault symptom indexes and instructions on how to usethem are in chapter 6. For each system of the truck, there is an index which givesyou a list of the fault symptoms for that system. The index also tells you where tofind the detailed troubleshooting procedures and what resources (tools/people) youneed to do each procedure.

2-6. SAMPLE TROUBLESHOOTING PROCEDURE. A sample troubleshooting procedureis in chapter 7. This sample procedure will help you see the way detailed trouble-shooting procedures are to be used.

TM 9-2320-211-34-1

CHAPTER 3

TROUBLESHOOTING INDEX

3-1. GENERAL. This chapter has a troubleshooting index which covers every systemof the truck on which you can do troubleshooting. The index tells you where to findall the other information you need to do your troubleshooting procedures.

3-2. INDEX. The troubleshooting index (figure 3-1) is divided into five columns thatlist systems, troubleshooting roadmaps, fault symptoms, summary troubleshootingprocedures, and system support diagrams. The following breakdown tells you whatis in each column.

a. System Column. This column gives a list of systems on the truck for whichtroubleshooting can be done at the direct support maintenance level.

b. Troubleshooting Roadmaps Column. This column tells you where to find thetroubleshooting roadmap for each listed system. These roadmaps are given inchapter 5.

c. Fault Symptom Index Column. This column tells you where to find thetroubleshooting fault symptom index for each listed system. Fault symptom indexesare given in chapter 6.

d. Summary Troubleshooting Procedures Column. This column tells you where tofind the summary troubleshooting procedure for each listed system. Some systems donot have summary troubleshooting procedures, so the column will be left blank forthose systems.

e. System Support Diagrams Column. This column tells you where to find supportdiagrams for each listed system. Some systems do not have support diagrams, so thecolumn will be left blank for those systems.

CHAPTER 7

SAMPLE TROUBLESHOOTING PROCEDURES

7-1. GENERAL. This chapter gives a sample troubleshooting procedure. The purposeof the sample procedure is to help you see how detailed troubleshooting procedures,test equipment procedures, and summary troubleshooting procedures are used to findfaults in a system.

7-2. SAMPLE DETAILED PROCEDURE. (See figure 7-1.) The sample detailed pro-cedure given is the fuel system troubleshooting procedure for the symptom, STARTERMOTOR WILL NOT CRANK ENGINE. This symptom is one you will have when you tryto start your truck and certain parts on the truck are not working correctly. In eachnumbered box, instructions are given which tell you what to do, and how to do it.A large dot is placed next to the “what-to-do” instructions, and small dots next to the"how-to-do-it" instructions.

a. Box number 1 givesstart to troubleshoot.

b. Box number 2 gives

general instructions on getting the truck ready before you

fault isolation test instructions. In this case you are toldto check starting system circuit for loose, burned, or broken leads and connections.These tests or checks, are often referred to in detailed troubleshooting procedures tohelp you find the problem and fix it. After you do the tests or checks you read thequestion at the bottom of box number 2. If the starter system is not okay, the answerto the question is so you go to the next box.

c. Box number 3 gives you a corrective action. In this case the fault is burnedor broken leads or connectors. The corrective action is what you do to fix the fault,which is to replace any burned or broken leads or connectors. If the engine stilldoesn’t start after you do this, it could mean that there are other faults in the system.When this happens, go back to the beginning of the procedure and do each step againuntil you find the other faults.

d. Sometimes the corrective actions given for a fault will tell you what to do to fixthe fault, but will not give you detailed instructions on how to fix it. Instead, youwill be told to refer to another volume in this manual for these instructions. Boxnumber 4 is an example of this.

9-2. TEST SET-UP. Instructions for setup of test equipment and parts to betested are given before the test procedures. Illustrations are used, when needed, toshow you how to hook up the test equipment to the part to be tested.

9-3. TEST PROCEDURE. Detailed step-by-step instructions, in flow chart form,are given for each test. The procedure calls out the type of test and the conditionof the truck system for each part of testing. The step-by-step test will lead you tothe bad component or to a fault symptom within a related system. Reference is madeto the fault symptom index, chapter 6, if the test shows a fault in another system.

This fine document...

Was brought to you by me:

Liberated Manuals -- free army and government manuals

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?

I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.

I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
