Backup memory read/write
error (engine PWB)
No response is issued from
the device in reading/writing
for 5 ms or more and this
problem is repeated 5 times
successively.
Mismatch of reading data from
2 locations occurs 8 times
successively.
Mismatch between writing
data and reading data occurs
8 times successively.
EEPROM(Engine
PWB)
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.
3. Replace the engine PWB (see page 1-5-
80).
4. Check the EEPROM and if the data are
currupted, contact the service support.
0160
Backup memory data error
(engine PWB)
Reading data from EEPROM
is abnormal.
EEPROM
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Execute U021 - memory initializing.(see
page 1-3-31)
3. If the EEPROM data are currupted,
contact the service support.
0170
Billing counting error
The values on the main circuit
PWB and on the engine do
not match for any of charging
counter, life counter, and
scanner counter.
EEPROM
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.
Main PWB
Replace the main PWB (see page 1-5-72).
Engine PWB
Replace the engine PWB (see page 1-5-80).
0180
Machine number mismatch
Machine number of main and
engine does not match.
Data damage of
EEPROM.
1. Confirm the machine data for the main
and engine units by using U004 (see
page 1-3-27).
2. If the serial number data of different
models is alternately displayed, install
the correct EEPROM in the PWB of the
wrong serial number data.
3. Contact the Service Support.
0350
Panel PWB communication
error (electronic volume I2C
communication error)
NACK is received during I2C
communication -> retried 5
times -> rebooting command
sent -> retried 5 times
If NACK is still received.
Operation PWB
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Confirm that the wiring connector is
firmly connected and, if necessary, con-
nect the connector all the way in.
Operation PWB (YC10) and Main PWB
(YC6)
3. If the wiring is disconnected, shorted or
grounded, replace the wiring.
Main PWB
Replace the main PWB (see page 1-5-72).
