To run the sensor input display mode, follow these steps

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

Turn the ignition switch to LOCK (0).
Press and hold both the AUTO and RECIRCULATION buttons, then start the engine.
After the engine starts, release both buttons. The display panel control unit will flash the sensor number and then the value for that sensor. Record the value displayed.

To advance to the next sensor, press the REAR WINDOW DEFOGGER/MIRROR HEATER button.

DISPLAY CHART

Sensor	Item	Displayed Value
1	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	10kcal/m² -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	Vehicle speed (Vehicle must be driven to display speed)	10km/h
8	Engine Coolant Temperature	°C
9	Target Vent Temperature Air Out (TAO)	°C
A	Humidity Sensor Value	%
b	Illumination duty	Step
C	Software version	-

NOTE:

The mode positioning will be displayed by BIT. Check the mode motor positioning by using the mode motor code information.
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 refer to checking DTCs by DTC indication to check for DTCs.
If necessary, compare the sensor input display to a like, 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.
Target vent temperature air out (TAO) is the value calculated by the climate control unit. It is determined by the conditions of the TEMP DIAL position, the outside air temperature, the in-car temperature, and the solar radiation.

To cancel the sensor input display mode, press the AUTO button or turn the ignition switch to LOCK (0).
