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

Table 2-2. Vehicle Troubleshooting.

(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.

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.

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 r1. Wanders, pulls to one side, or shimmies; 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.
