Service Manual
Causes
Defective NAND.
Turn the main power swtch off and after 5
seconds, then turn power on.
Defective PWB.
Replace the main PWB and check for cor-
rect operation (see page 1-5-31).

Check procedures/
corrective measures
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Execute U021 - memory initializing.(see
page 1-3-32)
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Check that the EEPROM is peroperly
installed on the engine PWB and re-
install it.
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Execute U021 - memory initializing.(see
page 1-3-32)
1. Check that the EEPROMs installed in
the main PWB and the engine PWB are
correct and, if not, use the correct
EEPROM for the model.
2. If the EEPROM data are currupted,
contact the service support.
