Error Codes Shown in the “MACHINE ERROR X X” message.
If the LCD shows the "PLS OPEN COVER" message, you can display the detailed error code
following the MACHINE ERROR, by using the maintenance-mode function code 82 described
in Chapter 7, Section 3.16.
NOTE:
•
When checking a PCB as instructed in the "Check:" column, check its harness also.
•
To check sensors, use the maintenance-mode function code 32 described in Chapter 7,
Section 3.9 (that is, press the
3
and
2
keys in the maintenance mode).
