Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the installation of the Temp/ Humidity
(Environmental) Sensor (REP 12.15 Temp/
Humidity (Environmental) Sensor on
page 4-225).
Is the Temp/ Humidity Sensor installed properly?
Go to step 2. Reinstall the Humidity
Sensor.
2. Check the connection between the Temp/
Humidity Sensor and MCU PWB.
Are the connectors P/J4651B and P/J465A
connected securely?
Go to step 3. Connect the
connectors P/J4651B
and P/J465A.
3. Check the conductivity between the Temp/
Humidity Sensor and MCU PWB.
Is the connection between P/J4651B <=>
P/J465A conducting properly?
Go to step 4. Replace the Main
Harness Assembly.
4. Check the voltage supply (+5VDC) to the Temp/
Humidity Sensor.
Measure the voltage between the MCU PWB
GND <=> P/J465A-B4.
Is there a voltage (approx. +5VDC) output?
Go to step 5. Go to +5VDC Power
