6. Self Diagnosis & Trouble Shooting
6-1. If the trouble is detected by self-diagnosis
To do list
☞ Checking method of R Sensor resistance
CN30 - “6”(White) ↔ CN76-"1"(Gray)
Compare the temperature table after
measurment.
☞ Checking method of R Sensor resistance
- Measure the voltage of Resistance R311(IC01 MICOM #84) on
PCB or CN30 - “6”(White) ↔ J23 JUMMPER
- Compare the temperature table after measurement. Measuring
voltage of CN30 - “6”(White) ↔ J23 JUMMPER are as below.
Is the input voltage of
IC01 MICOM #84 normal?
YES
NO
No trouble with PCB and
temperature sensor.
Recheck the bad contact of
the connection.
YES
Measuring voltage IC01 MICOM #84,
CN30 - “6”(White) and J23 JUMMPER
from PCB typical Ground part are similar.
→ Check the measure on the voltage of
Resistance,
R311 due to the SMD MICOM
Check the iced-solder, solder
bridging, disturbed solder.
