003-350 IOT-ESS Communication Failure 10
BSD on : CH12.2B
[Detection Conditions]
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 MCU PWB
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the MCU PWB (PL13.1).
003-351 IOT-ESS Communication Failure 11
BSD on : CH12.2B
[Detection Conditions]
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 MCU PWB
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the MCU PWB (PL13.1).
003-352 IOT-ESS Communication Failure 12
BSD on : CH12.2B
[Detection Conditions]
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 MCU PWB
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the MCU PWB (PL13.1).
003-353 IOT-ESS Communication Failure 13
BSD on : CH12.2B
[Detection Conditions]
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 MCU PWB
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.

replace the MCU PWB (PL13.1).
003-354 IOT-ESS Communication Failure 14
BSD on : CH12.2B
[Detection Conditions]
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 MCU PWB
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the MCU PWB (PL13.1).
003-355 IOT-ESS Communication Failure 15
BSD on : CH12.2B
[Detection Conditions]
The NAK that notifies the occurrence of the
communication failure is received. (A flaming 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 MCU PWB
Connection Harness.
(2) Software matching error. Perform re-installation of
the software.
(3) If the problem persists after the above actions,
replace the MCU PWB (PL13.1).
