5) If Ambient Sensor has trouble
Bad contact of connector/ insert correctly
Is
MAIN PCB Connector CN78 inserted
correctly?
Is
Ambient Sensor unit
normal?
Is the voltage between
MAIN PCB Connector CN78 ”8”(Yellow)
and J23 JUMMPER normal?
Is the
input voltage of IC01 MICOM #93
normal?

YES
Replace the 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 #93
CN78-"8"(Yellow) and J23 JUMMPER from
PCB typical Ground part are similar.
