Refer to circuit diagram in the manual
Sensor MICOM/Connector number
Ambient Connector CN32#1(White) to
CN1#3(Black) PCB typical Ground
Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #59,
CN32#1(White) and CN1#3(Black) from
PCB typical Ground part are similar.
Checking method of Ambient Sensor resistance
CN32#1(White) #4(White)
- Compare the temperature table after the
measure
38¢ (3¡ ) is recommended
Connector CN32 inserted
MAIN PCB Connector CN32#1(White)
to CN1#3(Black) normal?
IC01 MICOM #59 normal?
No trouble with PCB and temperature sensor
Recheck the bad contact of the connection
Checking method of Ambient Sensor voltage
- Measure the voltage of Sensor Check Point #7(IC01 MICOM #59)
on PCB or CN32#1(White)
- Compare the temperature table after the measure
Measuring voltage of CN32#1(White)
