7) If F DEF Sensor has trouble
ERROR Code
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
REG1-GND normal?
Is the input voltage of
IC01 MICOM #6 normal?
Start
NO
YES
YES
YES
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.

Sensor MICOM/Connector number
Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #6,
CN30-"5"(Orange) and REG1-GND from
PCB typical Ground part are similar.
→
Check the measure on the voltage of Resistance,
R310 due to the SMD MICOM
☞
Checking method of F DEF Sensor resistance
CN30-"5"(Orange)
↔
CN76-”1”(Gray)
- Compare the temperature table after
measurement.
DATA1.
Temperature table
Refer to circuit diagram in the manual
F DEF Connector CN30-"5"(Orange) to
REG1-GND PCB typical Ground
☞
Checking method of F DEF Sensor voltage
- Measure the voltage of Resistance, R310(IC01 MICOM #6) on PCB
or CN30-"5"(Orange)
↔
REG1-GND
- Compare the temperature table after measurement.
Measuring voltage of CN30-"5"(Orange)
↔
REG1-GND are as below
