Call Flow Diagram
-
This diagram outlines
the major activities that are performed
when a service call is made. The Initial
Actions assist the Service Representative
through the custornar interface and help
t o identify the problem.
The
diagram also
directs the Representative to verify,
classify, repair the problem and perform
the correct Maintenance Procedure.
Status Code Entry Chart
-
The chart
contains a list of Status Codes, their Cause,
the corresponding Clearance Procedure
and the Go t o RAPS (Repair Analysis
Procedures). The chart is designed t o
direct the Representative to the
appropriate Clearance Procedure. If the
Procedure does not clear the Status Code,
the Representative refers to the Go t o RAP
in Section
2
column. This column contains
the name of the RAP that must be
followed,
in
order t o repair the problem.
When the Status Code problem has been
repaired, refer to the Call Flow Diagram
and continue the Service Call.
NOTE:
The Status Code Entry Chart includes
status codes that may be generated by any one
o f several different firmware revisions. The
total number of status codes has been reduced
in later versions o f firmware. The chart has
been designed as a
cross
reference for
aN
the
firmware revisions.
Service Call Procedures
Consequently, the chart contains status codes
listed in the Status Code column that may be
different than the status codes listed i n the Go
To RAP In Section 2 column. For example,
status code
C2.51
is listed in the Status Code
column and C2.01
is
listed in the
corresponding Go To RAP In Section 2 column.
The
C2.01
RAP contains the information
required to isolate and repair the problem
that created the C2.51 status code.
