TROUBLESHOOTING INTRODUCTION

MALFUNCTION/SYMPTOM INDEX

The malfunction/symptom index (WP 0064 00) is a quick reference index for finding

troubleshooting procedures. Associated with each symptom name is a work package

sequence number representing the starting point in a troubleshooting sequence. Should

any one symptom require more than one troubleshooting sequence to arrive at the most

likely area of investigation, the additional starting point numbers are presented.

As the troubleshooting activity progresses through to the conclusion of a particular

sequence, a reference is made to the next logical troubleshooting sequence by work

package sequence number, or by referring to the malfunction/symptom index to locate the

next failure symptom work package. This type of activity continues until successful fault

isolation is achieved.

TROUBLESHOOTING PROCEDURES

The troubleshooting work packages contain tables listing the malfunctions, tests or

inspections, and corrective action required to return the vehicle to normal operation.

Perform the steps in the order they appear in the tables.

Each work package is headed by an initial setup. This setup outlines what is needed, as

well as certain conditions which must be met before starting the task. DON'T START A

TASK UNTIL:

You understand the task.

You understand what you are to do.

You understand what is needed to do the work.

You have the things you need.

This manual cannot list all malfunctions that may occur, or all tests or inspections and

corrective actions. If a malfunction is not listed or is not corrected by listed corrective

actions, notify Field Maintenance.
