6-1. If the trouble is detected by self-diagnosis
6. Self Diagnosis & Trouble Shooting
To do list
Start
Is MAIN PCB
Connector CN30 and CN76 inserted
correctly?
Is R DEF Sensor
unit normal?
YES
Bad contact of connector/
insert correctly
NO
YES
NO
3) If R DEF Sensor has trouble
Is the input voltage between
MAIN PCB Connector
CN30-”8”(Skyblue) and
J23 JUMMPER normal?
NO (0.6V > Measurement < 4.6V)
Sensor MICOM/Connector Number
R DEF
Connector CN30-"8"(Sky-
blue) and J23 JUMMPER
PCB typical Ground
Voltage measured between 4.6V ~ 0.6V.
Replace the temperature
sensor
Recheck the wire connection
part
Refer to circuit diagram in the manual
