Sensor MICOM/Connector number
F DEF Connector CN30-"5"(Orange) to
J23 JUMMPER PCB typical Ground
Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #83,
CN30-"5"(Orange) and J23 JUMMPER 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.
Start Start
Are
MAIN PCB Connector CN30 and CN76
insert correctly?
YES YES
IS
FZ DEF Sensor unit
normal?
YES YES
Is the voltage between
MAIN PCB Connector CN30-"5"(Orange) and
J23 JUMMPER normal?
YES YES
Is the input voltage of
IC01 MICOM #83 normal?
YES
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.
☞ Checking method of F DEF Sensor voltage
- Measure the voltage of Resistance, R310(IC01 MICOM #83) on PCB
or CN30-"5"(Orange) J23 JUMMPER
↔
- Compare the temperature table after measurement.

NO
Bad contact of connector/ insert correctly
NO
Replace temperature sensor
NO(0.6V > Measurement < 4.6V)
Recheck the wiring connection
NO
Check the iced-solder, solder
bridging, disturbed solder
