TROUBLESHOOTING
4) If R DEF Sensor has trouble
ERROR Code
Bad contact of connector/ insert correctly
Is MAIN PCB
Connector CN30 and CN76 inserted
correctly?
Is R DEF Sensor
unit normal?
Is the input voltage between
MAIN PCB Connector CN30-”8”(Skyblue)
and REG1-GND normal?
Is the input voltage of IC01
MICOM # 3 normal?
Start
NO
YES
YES
YES
YES
Replace the temperature sensor
NO
Recheck the wire connection part
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.

Sensor MICOM/Connector Number
Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #3
CN30-"8"(Sky-blue) and REG1-GND from
PCB typical Ground part are similar.

Check the measure on the voltage of Resistance R313
due to the SMD MICOM
☞
Checking method of R Sensor resistance CN30-
"8"(Sky-blue)
↔
CN76-"1"(Gray)
- Compare the temperature table after
measurement.

☞
Checking method of R DEF Sensor resistance
- Measure the voltage of Resistance R313(IC01 MICOM #3) on
PCB or CN30-”8”(Sky-blue)
