Voltage measured between 4.6V ~ 0.6V.

Measuring voltage of IC01 MICOM #72,

CN31-"1"(Yellow) and REG1, HEAT SINK from

PCB typical Ground part are similar. Check the measure on the SENSOR MARKING

#7(R307) due to the SMD MICOM

Start

Is MAIN PCB		NO
Connector CN31 inserted
correctly?
	YES
		NO	Bad contact of connector/ insert correctly
Is Ambient Sensor
unit normal?
	YES		Replace the temperature sensor
Is the voltage between		NO(0.6V > Measurement < 4.6V)
MAIN PCB Connector CN31#1(Yellow) and REG1,
HEAT SINK normal?
	YES	NO	Check the contact of PCB & Wire Terminal correctly.
Is the input voltage of
IC01 MICOM #72 normal?
	YES		Check the iced-solder, solder bridging,
			disturbed solder. Replace the PCB
No trouble with PCB and temperature sensor
Recheck the bad contact of the connection

Checking method of Ambient Sensor resistance CN31#1(Yellow) #4(Yellow)

-Compare the temperature table after the measure

Checking method of Ambient Sensor voltage
- Measure the voltage of Sensor Check Point #7
(IC01 MICOM #72) or CN31#1(Yellow) REG1, HEAT SINK.	typical PCB Ground
- Compare the temperature table after the measure. Measuring
voltage of CN31#1(Yellow) REG1, HEAT SINK are below.	REG1 HEAT-SINK
