003-328 IISS-ESS Communication Failure 9
BSD on : CH12.2A
[Detection Conditions]
SCOPE-FD sending error that will be detected by the
Controller (Sending Abortion Error)
ACK cannot be received after resending it twice.
(Abortion of receiving is detected after a header is
recognized at the IISS side.)
[Actions]
Turn the power On/Off and perform the following if
the problem persists.
(1) Check the connection of the IIT/IPS (PL16.3)
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the IIT/IPS (PL16.3).
003-329 IISS-ESS Communication Failure 10
BSD on : CH12.2A
[Detection Conditions]
SCOPE-FD receiving error that will be detected by the
Controller (Sequence No. Error)
The NAK that notifies the occurrence of the
communication failure is received. (The Sequence No.
of the message packet that has been received is not
correct.)
[Actions]
Turn the power On/Off and perform the following if
the problem persists.
(1) Check the connection of the IIT/IPS (PL16.3)
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the IIT/IPS (PL16.3).
003-330 IISS-ESS Communication Failure 11
BSD on : CH12.2A
[Detection Conditions]
SCOPE-FD receiving error that will be detected by the
Controller (Incorrect Packet No.)
The NAK that notifies the occurrence of the
communication failure is received. (The Packet No. of
the message packet that has been received is not
correct.)
[Actions]
Turn the power On/Off and perform the following if
the problem persists.
(1) Check the connection of the IIT/IPS (PL16.3)
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the IIT/IPS (PL16.3).
003-331 IISS-ESS Communication Failure 12
BSD on : CH12.2A
[Detection Conditions]
SCOPE-FD receiving error that will be detected by the
Controller (Incorrect Message Length)
The NAK that notifies the occurrence of the
communication failure is received. (The message
length of the message packet that has been received is
not correct.)
[Actions]
Turn the power On/Off and perform the following if
the problem persists.
(1) Check the connection of the IIT/IPS (PL16.3)
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the IIT/IPS (PL16.3).

BSD on : CH12.2A
[Detection Conditions]
SCOPE-FD receiving error that will be detected by the
Controller (Check Code Error)
The NAK that notifies the occurrence of the
communication failure is received. (The Check Code
of the message packet that has been received is not
correct.)
[Actions]
Turn the power On/Off and perform the following if
the problem persists.
(1) Check the connection of the IIT/IPS (PL16.3)
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the IIT/IPS (PL16.3).

BSD on : CH12.2A
[Detection Conditions]
SCOPE-FD receiving error that will be detected by the
Controller (Parity Error)
The NAK that notifies the occurrence of the
communication failure is received. (A parity error is
found in the hardware the UART itself has.)
[Actions]
Turn the power On/Off and perform the following if
the problem persists.
(1) Check the connection of the IIT/IPS (PL16.3)
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the IIT/IPS (PL16.3).
