5) If F Sensor has trouble
Bad contact of connector/ insert correctly
Are MAIN PCB
Connector CN30 to CN76 inserted
correctly?
Is F Sensor
unit normal?
Is the voltage between
MAIN PCB Connector CN30#3 (Red) and REG1,
HEAT SINK normal?
Is the input voltage of
IC01 MICOM #81 normal?

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

Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #81,
CN30-"3"(Yellow) and REG1, HEAT SINK from PCB
typical Ground part are similar.

Checking method of F Sensor voltage
- Measure the voltage of Sensor Check Point #1
(IC01 MICOM #81) or CN30#3(Red) REG1, HEAT SINK.
- Compare the temperature table after the measure. Measuring
