3) If R DEF Sensor has trouble
Bad contact of connector/ insert correctly
Is MAIN PCB
Connector CN30 to CN75 inserted
correctly?
Is R DEF Sensor
unit normal?
Is the input voltage between
MAIN PCB Connector CN30#7(Skyblue)
to CN1#3(Black) normal?
Is the input voltage of IC01
MICOM # 57 normal?

YES
YES
Replace the temperature sensor
NO
Recheck the wire connection part
NO(0.6V > Measurement < 4.6V)
Check the iced-solder, solder bridging,
disturbed solder.
NO
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.
