3) When the R-DEF-Sensor is defective
MAIN PCB Connector
CN31 is inserted properly?
F-DEF Sensor is
normal?
Voltage between MAIN PCB
Connector CN31-"7"(WHT) and "8"(WHT)
is normal?
Input Voltage at IC01
MICOM Pin #54 is normal?
Start
PCB and Temp Sensor are normal.
Check the connector contact.

Sensor MICOM/Connector #
F DEF
Between Connector
CN31 - "7"(WHT) and
CN31 -"8"(WHT)
Voltage : Between 4.6V ~ 0.6V
** Sensor Resistance Reading Location **
F-DEF : Between CN31 #7 and #8
** 0Ω : Short / ∞Ω : Open
Voltage at IC01 MICOM # 54 is the
same as the value between
CN31-"7"(WHT) and CN31-"8"(WHT).
