6. Self Diagnosis & Trouble Shooting
6-1. If the trouble is detected by self-diagnosis
To do list
☞ Checking method of Ambient Sensor
resistance CN78-”8”(Yellow) ↔
"12"(Yellow)
- Compare the temperature table after
measurement.
☞ Checking method of Ambient Sensor voltage
- Measure the voltage of Resistance R315(IC01 MICOM #93) on
PCB or CN78-"8"(Yellow) ↔ J23 JUMMPER
- Compare the temperature table after measurement.
Measuring voltage of CN78-"8"(Yellow) ↔ J23 JUMMPER are as
below
Is the input voltage of IC01
MICOM #93 normal?
YES
NO
No trouble with PCB and
temperature sensor
Recheck the bad contact of
the connection
YES
Measuring voltage of IC01 MICOM #93
CN78-"8"(Yellow) and J23 JUMMPER
from PCB typical Ground part are similar.
→ Check the measure on the voltage of
Resistance, R315 due to the SMD
MICOM
Check the iced-solder, solder
bridging, disturbed solder
PCB Typical Ground
J23 JUMMPER
