2) When the EXT-Sensor is defective
MAIN PCB Connector
CN31 is inserted properly?
EXT Sensor is
normal?
Voltage between
MAIN PCB Connector CN31-"1"(WHT)
and CN31-"2"(WHT)?
Input Voltage at IC10
MICOM Pin #21 is normal?
Start
PCB and Temp Sensor are normal.
Check the connector contact.
Connector contact defect / Reconnect
Replace Temp Sensor
Check the wire connection

Sensor MICOM/Connector #
Ambient
Between Connector CN31-
"1"(WHT) and CN31-
"2"(WHT)
Voltage : Between 4.6V ~ 0.6V
** Sensor Resistance Reading Location **
Ambient : Between CN31 #1 and #2.
** Located in the PCB Box
** 0Ω : Short / ∞Ω : Open
Voltage at IC10 MICOM #23
is the same as the value
between CN31-"1"(WHT)
and CN31-"2"(WHT) of the
CN31 on MAIN PBA.
