Diagnostic test results
The following table lists each test result along with the normal value range for each
item.
"OK" appears for normal operation. If "NG" (No Good) appears, corresponding com-
ponents may be defective.
Also, if a connected fan or PCB shows the check results as asterisks, it is an indication
that the fan or PCB has failed, or is disconnected.
If there are any component which are suspected to be defective, or any test does not
complete satisfactorily, consult your dealer for advice.
