General Troubleshooting Information (cont'd)
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 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 control knob to the desired test temperature. When selecting the test temperatures, 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.
• 61 through 89°F settings will use the automatic climate control logic.
3. Turn the ignition switch OFF.
To run the sensor input display mode, follow these steps
1. Turn the ignition switch OFF.
2. Press and hold both the AUTO and RECIRC buttons, then start the engine.
3. After the engine starts, release the buttons. The climate control display will flash the sensor number and then the
value for that sensor. Record the value displayed.
