1 Service Call Procedures
Introduction
The Service Call Procedures section is used to
identify a suspected problem.
This section
contains Call Flow, tnitial Actions, System Checks,
Additional Checks, Subsystem Maintenance. and
Final Actions.
Initial Actions are used to gather information
regarding the performance of the machine and
prepare the product for servicing.
System Checks are used to verify the normal
operation of the machine. In the Y/N (Yes/No)
steps of the system checks, a Yes response will
lead you lo the next step. A No response will
indicate the next step to perform or will direct you
to a Repair Analysis Procedure (RAP).
Additional Checks test various machine functions
not directly tested by system checks.
RAPS will provide the instructions to isolate the
faulty part or provide a list of suspect parts, when
isolation is not appropriate. Wire harnesses are
not included in the repair actions and problems
with loose connections or damaged harnesses
should be isolated using visual inspection and the
wiring data in section 7.
Subsystem Maintenance contains routine
maintenance procedures.
Final Actions are used to evaluate the total
operation of the system and to identify the actions
required to complete the service call.
