cable (A), then remove the opener (B). Take care
not to kink the cable.
7. Install the opener in the reverse order of removal, and note these items:
 Make sure the opener cable is connected properly.
 Make sure the trunk lid and fuel fill door open properly and lock securely.
 If the trunk lid or the fuel fill door does not open properly, adjust the position of the cable end on
the opener.

Displaying Sensor Inputs at the Climate Control Unit
Check these items before using the sensor input display mode
To run the sensor input display mode, follow these steps
21-13
The climate control unit has a mode that displays the sensor inputs it receives. This mode shows you what data 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.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 control knob to the desired test temperature. 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.
 19 through 31 °C settings will use the automatic climate control logic.
3. Turn the ignition switch to LOCK (0).
1. Turn the ignition switch to LOCK (0).
2. Press and hold both the AUTO and MODE buttons, then start the engine.
3. After the engine starts, release both buttons. The display panel will flash the sensor number and then the value for that sensor. Record the value displayed.
4. To advance to the next sensor, press the A/C button. Sensor Item Displayed Value1 Mode Positioning BIT
2 In-car Temperature °C
3 Outside Air Temperature °C
4 Solar Radiation Sensor Value: Dark = 00, Flashlight = 04, Cloudy = 10, Sunny = 65 10 kcal/m ·h
5 Evaporator Outlet Air Temperature °C
6 Air Mix Opening (Low value indicates cooler air distribution, higher value indicates warmer air distribution) % of opening
7 Recirculation Opening % of opening
8 Vehicle Speed (Vehicle must be driven to display speed) km/h
9 Engine Coolant Temperature °C
A Vent Temperature Air Out (TAO) °C
NOTE:  The sensor values will be displayed in degrees Celsius (°C) or an alphanumeric code. Use the chart to convert the value to degrees Fahrenheit (°F).
 If the sensor value displays ‘‘Er’’ this indicates there is an open or short in the circuit or sensor. Check for DTCs using the HDS, or use the climate control self-diagnostic function.
 If necessary, compare the sensor input display to a known-good vehicle under the same test conditions.
 If the sensor is out of the normal range, refer to the sensor test or substitute a known-good sensor, and recheck.
5. To cancel the sensor input display mode, press the AUTO button or turn the ignition switch to LOCK (0). (cont’d)
