System Technician-Demanded Tests: Descriptions
and error codes
Always investigate problems in the order presented. When you clear one of the
error codes associated with a given test, you clear errors generated by other
tests in the testing sequence. If you clear errors out of order, you can lose
important information.
If Then
Error Type 1538 is also
present
Circuit pack is taken out of service
If Error Type 1538 is not
present
Circuit pack is
not
taken out of service,
but has generated 50% of the messages
necessary to be considered hyperactive.
■ This may be normal during heavy
traffic.
■ If the error is logged during light
traffic, it may indicate a problem with
the circuit pack or the equipment
attached to it.
