003-343 IOT-ESS Communication Failure 4
BSD on : CH12.2B
[Detection Conditions]
ACK cannot be received after resending it twice. (The
message length of the message packet that has been
sent 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).
003-345 IOT-ESS Communication Failure 5
BSD on : CH12.2B
[Detection Conditions]
ACK cannot be received after resending it twice. (The
Check Code of the message packet that has been sent
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).
003-346 IOT-ESS Communication Failure 6
BSD on : CH12.2B
[Detection Conditions]
ACK cannot be received after resending it twice. (A
parity error is found in the hardware at the IOT side.)
[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).
003-347 IOT-ESS Communication Failure 7
BSD on : CH12.2B
[Detection Conditions]
ACK cannot be received after resending it twice. (A
flaming error is found in the hardware at the IOT
side.)
[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).
003-348 IOT-ESS Communication Failure 8
BSD on : CH12.2B
[Detection Conditions]
ACK cannot be received after resending it twice. (An
overrun error is found in the hardware at the IOT
side.)
[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).
003-349 IOT-ESS Communication Failure 9
BSD on : CH12.2B
[Detection Conditions]
ACK cannot be received after resending it twice.
(Abortion of receiving is detected after a header is
recognized at the IOT side.)
[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).
