6-1. If the trouble is detected by self-diagnosis
6. Self Diagnosis & Trouble Shooting
To do list
Start
Are MAIN PCB
Connector CN30 and
CN76 insert correctly?
IS FZ DEF Sensor
unit normal?
YES
Bad contact of connector/
insert correctly
NO
YES
NO
6) If F DEF Sensor has trouble
Is the voltage between
MAIN PCB Connector
CN30-
”5”(Orange) and
J23 JUMMPER normal?
NO
(0.6V > Measurement < 4.6V)
Sensor MICOM/Connector number
F DEF
Connector CN30-"5"(Orange)
to J23 JUMMPER PCB
typical Ground
Voltage measured between 4.6V ~ 0.6V.
Replace temperature sensor
Recheck the wiring
connection
Refer to circuit diagram in the manual
