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?

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 voltage of IC01 MICOM #82,
CN30-”4”(Red) and J23 JUMMPER from
PCB typical Ground part are similar.
