6) If F DEF Sensor has trouble
Bad contact of connector/ insert correctly
Are
MAIN PCB Connector CN30 and CN76
insert correctly?
IS
FZ DEF Sensor unit
normal?
Is the voltage between
MAIN PCB Connector CN30-”5”(Orange) and
J23 JUMMPER normal?
Is the input voltage of
IC01 MICOM #83 normal?

YES
Replace temperature sensor
NO
Recheck the wiring connection
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.
