b. TM 1–1520–238–T–2, Master Failure Symptom Index.
TM 1–1520–238–T–2 lists all integrated
troubleshooting failure symptoms in alphabetical order. Each failure symptom refers you to the appropriate MOC
in another volume. Additional troubleshooting information can be found by using the display symbology data found
in chapter 1. You can refer to this volume for all types of failures, i.e., audio/visual, loss of power, short or open
exists, etc.
c. TM 1–1520–238–T–3, Multiplex (MUX) Read Codes.
TM 1–1520–238–T–3 contains Multiplex (MUX)
Read Code interpretations by system. You are directed to go to this volume from MOCs in subsystem volumes.
You can use this volume as an aid to interpret MUX read codes and locate faults. You are directed to the
appropriate volume, to remove or replace a failed LRU or to a failure symptom within this volume.
