Inspect the Event Log to obtain failure reason codes:
a. Select Event from the Logs menu at any view. The Event Log
displays.
b. Record the event code and associated date, time, and severity
(Informational, Minor, Major, or Severe).
c. If multiple event codes are found, record all codes and severity
levels. Record the date, time, and sequence, and determine if all
codes are related to the reported problem. Begin fault isolation
with the most recent event code with the highest severity level.
Other codes may accompany this event code, or may indicate a
normal indication after a problem is recovered.
Were one or more event codes found?
NO YES
↓
Go to Table 3-3 to obtain event codes. Exit MAP.
Return to step 1 and perform fault isolation again. If this is the
second time at this step, perform a data collection and contact the
next level of support. Refer to
Collect Maintenance Data . Exit MAP.
