Troubleshooting tree (T920 and T1500 only)
As a general approach, the following tree should be followed to troubleshoot any issue. This helps
understand at which point the problem was caused. The tree is sequential; before checking a subsystem, the
previous steps need to be working. Once a sub system is identified as causing the problem, the service and
utilities related to that component can be used to troubleshoot further. See Diagnostics, Service Utilities and
Calibrations on page 159.
