TM 9-2320-366-34-1 b.    How to Begin Troubleshooting. (1)    Determine  the  symptom  or  condition  that  indicates  a  problem  or  failure.  Troubleshooting  is  divided  into symptoms peculiar to a vehicle system or component, for example: pneumatic system or engine. Refer to the Troubleshooting Fault Index (Table 2-1). (2)    Go to the referenced page to begin troubleshooting. Open the manual flat so both the left-hand and right-hand pages are displayed before you. The information on both pages is important to resolve the problem or failure. However, the experienced technician can follow the left-hand page instructions and refer to the right-hand page when necessary. (3)    Follow the Diagnostic Procedure. Answer question No. 1 on the left-hand page and follow the YES or NO path to either the remedy or the next question. If necessary, look on the right-hand page for test instructions and illustrations. (4)    Observe  warnings,  cautions,  and  notes.  The  formatting  and  symbols  used  in  this  manual  for  warnings, cautions, and notes are as follows: WARNING This is the symbol for a warning statement. If you see the word WARNING above a question on the left-hand page, look on the right-hand page for the text of the message. WARNINGs describe a situation which could cause serious injury or death to personnel. CAUTION This is the symbol for a caution statement. If you see the word CAUTION above a question on the left- hand page, look on the right-hand page for the text of the message. CAUTIONs describe a situation which could cause damage to equipment. NOTE This  is  a  symbol  for  a  note.  Notes  are  located  directly  above  the  test  to  which  they  refer.  NOTEs provide additional information for performing a test. c. Confidence  Tests.    Before  performing  any  STE/ICE-R  test,  a  confidence  test  must  be  run  to  ensure  proper operation  of  the  STE/ICE-R.    In  addition,  a  confidence  test  must  be  performed  after  each  use  to  ensure  the STE/ICE-R is performing properly.   Refer to TM 9-4910-571-12&P. d.    Verifying Repair.  When troubleshooting, there is an additional step that must be performed after taking any corrective action. This step will show that the malfunction has been corrected, or that additional troubleshooting is required, example follows: On malfunction g2. Leans to one side, or rear of vehicle sags, the question is asked "Are front shock absorbers secure and free from damage?". If the question was answered NO, the damaged shock absorber(s) was replaced. After replacing the damaged shock absorber(s), the vehicle must be checked to determine if the original malfunction is still present. If corrected, troubleshooting is completed. If malfunction is still present, continue troubleshooting. 2-7
