Step Check description Assumed cause Measures Reference
1 Resetting the main power The EEPROM does not
operate properly.
Turn off the power switch and
unplug the power cord. After
5s passes, reconnect the
power cord and turn on the
power switch.
2 Reinstalling the EEPROM The EEPROM is not prop-
erly attached.
Reattach the EEPROM on
the main/engine PWB.
3 Replacing the EEPROM The EEPROM is faulty. Replace the EEPROM on the
main/engine PWB and exe-
cute U004.
4 Checking the main/engine
PWB
The connector is not con-
nected properly or the wire
or main/engine PWB is
faulty.
Reconnect the connector of
the main/engine PWB. If the
wire is pinched or scratched,
repair or replace it. If not
repaired, replace the main/
engine PWB.

Step Check description Assumed cause Measures Reference
1 Checking the machine
serial number in the
EEPROM on the main/
engine PWB
The main/engine PWB for
the different main unit is
installed.
Check the main and engine
machine serial number in
U004 and if the main number
is different, attach the correct
main/engine PWB.
