3) When the DEF-Sensor is defective
MAIN PCB Connector
CN30 is inserted
properly?
F-DEF Sensor is
normal?
Voltage between MAIN
PCB Connector CN30-"4"(RED)
and CN76-"1"(BRN)
Input Voltage at IC10
MICOM Pin #24 is normal?
Start
PCB and Temp Sensor are normal.
Check the connector contact.
Connector contact defect /
Reconnect
Replace Temp Sensor
Check the wire connection

DEF
Between Connector CN30"-
"4"(RED) and CN76-"1"
(BRN)
Voltage : Between 4.6V ~ 0.6V
** Sensor Resistance Reading Location **
F-DEF : Between CN30 #4 and CN76 #1
** 0Ω : Short / ∞Ω : Open
Voltage at IC10 MICOM #
24 is the same as the value
between CN30-"4"(RED)
and CN76-"1"(BRN).
