TROUBLESHOOTING

6) If F DEF Sensor has trouble

Bad contact of connector/ insert correctly

Are 

MAIN PCB Connector CN30 and CN76 

insert correctly?

IS 

FZ DEF Sensor unit 

normal?

Is the voltage between

MAIN PCB Connector CN30-”5”(Orange) and

J23 JUMMPER normal?

Is the input voltage of

IC01 MICOM #83 normal?

Start

NO

YES

YES

YES

YES

Replace temperature sensor

NO

Recheck the wiring connection

NO(0.6V > Measurement < 4.6V)

Check the iced-solder, solder

bridging, disturbed solder

NO

No trouble with PCB and temperature sensor.

Recheck the bad contact of the connection.
