Measures
Check the main and engine
machine serial number in
U004 and if the engine num-
ber is different, install the cor-
rect EEPROM in the main/
engine PWB.
Check the main and engine
machine serial number in
U004 and if the main number
is different, replace the main/
engine PWB and execute
U004.
Check the main and engine
machine serial number in
U004 and if the engine num-
ber is different, reinstall the
EEPROM in the main/engine
PWB. If not repaired, replace
the EEPROM and execute
U004.
Note: Do not execute U004
(selecting [Execute] and
pressing the [Start] key). A
different machine serial num-
ber is overwritten.
Replace the main/engine
PWB.
Measures
Check the main and engine
machine serial number in
U004 and if the main number
is different, attach the correct
main/engine PWB.
Check the main and engine
machine serial number in
U004 and if the engine num-
ber is different, install the cor-
rect EEPROM in the main/
engine PWB.
Check the main and engine
machine serial number in
U004 and if the main number
is different, replace the main/
engine PWB and execute
U004.
