Displaying Sensor Inputs at t h e Climate Control Unit
The climate control unit has a m o d e that displays sensor inputs it receives. This mode shows y o u w h a t the climate
control unit is receiving f r o m each of the sensors, one at a t i m e , and it can help y o u determine if a sensor is faulty.
Check these items before using the sensor input display mode

f r o m FRESH to RECIRC. The air v o l u m e and sound should change slightly.
2. Set the temperature control knob to the desired test temperature. W h e n selecting the test temperature, note these
items:
• " L o " temperature setting w i l l default to M A X COOL, VENT, and RECIRC.
• " H i " temperature setting w i l l default to M A X HOT, FLOOR, and FRESH.
• 58 t h r o u g h 86 °F settings w i l l use the automatic climate control logic.
3. Turn the ignition switch OFF.
To run the sensor input display mode, follow these steps

the value to degrees Fahrenheit (°F).
• If the sensor value displays " E r " , this indicates there is an open or short in the circuit or sensor. Check for DTCs
using the HDS, or refer to checking DTCs by DTC indication to check for DTCs.
• If necessary, compare the sensor input display to an alike, k n o w n - g o o d vehicle under the same test conditions.
