Displaying Sensor Inputs at the Climate Control Unit
The climate control unit has a mode that displays sensor inputs it receives. This mode shows you what the climate
control unit is receiving from each of the sensors, one at a time, and it can help you determine if a sensor is faulty.
Check these items before using the sensor input display mode
1. Turn the ignition switch to ON (II), and check the recirculation door function; press the recirculation button to
switch from FRESH to RECIRC. The air volume and sound should change slightly.
2. Set the temperature using the driver's control switch to the desired test temperature:
• Press AUTO button on, the LED turns on.
• Press DUAL button off, the LED turns off.
When selecting the test temperature, note these items:
• ''Lo'' temperature setting will default to MAX COOL, VENT, and RECIRC.
• ''Hi'' temperature setting will default to MAX HOT, FLOOR, and FRESH.
• 58 through 86 °F settings will use the automatic climate control logic.
3. Turn the ignition switch to LOCK (0).
