Troubleshooting Procedure Table
Step Actions and Questions Yes No
1 Check the Humidity/Temperature
Sensor for correct installation. Is the
Humidity/Temperature Sensor
correctly installed?
Go to step 2. Reseat the
Humidity/
Temperature
Sensor. Go to
step 2.
2 Does the error still occur? Go to step 3. Complete.
3 Check the wiring harness connectors
P/J26 and P/J261 between the MCU
Board and the Humidity/Temperature
Sensor. Are the connectors securely
connected?
Go to step 4. Reconnect the
connectors.
4 Check the Humidity/Temperature
Harness for continuity.
1. Disconnect P/J26 and P/J261.
2. Check continuity between P/J26 <=>
P/J261.
Go to step 5. Replace the
Humidity/
Temperature
Harness.
5 Check the Humidity/Temperature
Sensor signal.
1. Disconnect P/J26 from the MCU
Board.
2. Is there +5 V across ground <=>
J26-4?
Replace the
Humidity Sensor
(page 8-86).
Replace the
MCU Board
(page 8-87).
