6) If F Sensor has trouble
Bad contact of connector/ insert correctly
Are MAIN PCB
Connector CN30 and CN76
inserted correctly?
IS
F Sensor unit normal?
Is the voltage between
MAIN PCB Connector CN30-”4”(Red) and
J23 JUMMPER normal?
Is the input voltage of
IC01 MICOM #82 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
** Measuring point of resistance value according to
Sensor **
F : CN30-”4” ↔ CN76-”1” measuring resistance value
** 0Ω: Short trouble / Ω∞: Open trouble
Sensor MICOM/Connector number
Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #82,
CN30-”4”(Red) and J23 JUMMPER from
PCB typical Ground part are similar.
→ Check the measure on the voltage of Resistance,
R309 due to the SMD MICOM
☞ Checking method of F Sensor resistance CN30-
"4"(Red)
↔ CN76-"1"(Gray)
-
Compare the temperature table after measurement.

Checking method of F Sensor voltage
- Measure the voltage of Resistanec, R309(IC01 MICOM #82) on PCB or
CN30-"4"(Red)
↔
J23 JUMMPER
- Compare the temperature table after measurement.
