(2) Execution result of self-diagnostics
(a) TEST LED OFF (When normally completed)
(b) TEST and FAULT LEDs ON (When failed)
(c) Values that may be stored in the Offline test status area (Un\G2258)
When the TEST LED turns OFF after execution of self-diagnostics, this indicates
a normal completion.
If the TEST and FAULT LEDs are ON after execution of self-diagnostics, this
indicates that the diagnostics failed.
Check the value stored in the Offline test status area (Un\G2258), and retry the
self-diagnostics.
If the diagnostics fails again, a QJ71PB92V hardware error is probable.
Please check the value currently stored in the Offline test status area (Un\G2258),
and consult your local Mitsubishi representative.
