6. Self Diagnosis & Trouble Shooting
6-1. If the trouble is detected by self-diagnosis
To do list
☞
Checking method of F Sensor resistance
CN30-
"4"(Red) ↔ CN76
-"1"(Gray)
- Compare the temperature table after
measurement.
☞
Checking method of F Sensor voltage
- Measure the voltage of Resistanec, R309(IC01 MICOM #82) on PCB
or CN30-
"4"(Red) ↔J23 JUMMPER
- Compare the temperature table after measurement.
Measuring voltage of CN30-
"4"(Red)↔J23 JUMMPER are as below.
Is the input voltage of
IC01 MICOM #82 normal?
YES
NO
No trouble with PCB and
temperature sensor
Recheck the bad contact of
the connection
YES
Measuring voltage of IC01 MICOM #82,
CN30-
”4”(Red) and J23 JUMMPER from
PCB typical Ground part are similar.
→ Check the measure on the voltage of
Resistance, R309 due to the SMD
MICOM
Check the iced-solder, solder
bridging, disturbed solder
PCB Typical Ground
J23 JUMMPER
