Status Indicator Repair Analysis Procedures
Initial Issue
Introduction
The Repair Analysis Procedures section is used to isolate and identify problems to a faulty
component or subassembly. It contains the Introduction, display message table, error code
table and the Repair Analysis Procedures (RAPs).
Use the Display Messages and Error Codes tables when messages are displayed or error
codes are printed in a report.
The Repair Analysis Procedures (RAPs) are accessed from Section 1, system checks or addi-
tional checks. There are two types of RAPs: Status Indicator (SI) RAPs, contained in this sec-
tion, and Image Quality (IQ) RAPs, located in Section 3.
RAPs will normally isolate a problem to a specific component or subassembly, excluding the
wire harnesses.
In the Y/N (Yes/No) steps of the RAPs, a Yes/No response will either lead you to the next step
or will indicate a corrective action. When the indicated corrective action has been completed,
go to Section 1 and restart the System Check to verify that the problem has been corrected.
Measurements
Power and signal grounds are connected to frame ground, therefore all circuit troubleshooting
can be performed using the metal frame (chassis) as the grounding point. If more information is
needed to locate connectors or test points, refer to section 7.
Unless otherwise specified, the following voltage tolerances are used within this section: Table
