Troubleshooting Procedure
Step Actions and Questions Yes No
1 Check the connections between the
MCU Board and Humidity Sensor.
Are P/J20 and P/J201 connected
surely?
Go to step 3. Reconnect the
connector(s) P/
J20 and/or P/
J201 surely,
then go to
step 2
2 Does the error still occur when the
power is turned Off and On?
Go to step 3. Complete.
3 Disconnect P/J20 from the MCU
Board.
Disconnect P/J201 from the Humidity
Sensor.
Is each wire of P/J20 <=> P/J201
continuous?
Go to step 4. SFP: Replace
the Humidity
Harness Assy.
(PL 9.1.6)
MFP: Replace
the Left Side
Harness Assy.
(PL 3.1 18)
4 Disconnect P/J20 on the MCU Board.
Is the voltage across ground <=> J20-4
on the MCU Board, about +5VDC?
Replace the
Humidity
Sensor. (SFP,
