Temperature/Humidity Sensor Error (PCU)
One of the following occurred.
• The temperature sensor output was less than 0.5V or more than
2.8V for three seconds (one second x 3), indicating a problem with
the temperature sensor.
• The humidity sensor output was more than 2.4V for three seconds
(one second x 3), indicating a problem with the humidity sensor.
Details:
Detection is repeated after power off/on.
If either of temperature/humidity sensors works correctly, the working
sensor will be used even after the SC is issued.
The machine continues working with the assumption that the temperature
is 23 degrees centigrade (if there is a problem with the temperature
sensor) and/or the humidity is 50% (if there is a problem with the
humidity sensor).
• Connector disconnected or harness broken
• Sensor defective
• Connector disconnected or harness broken: Revert connection.
