AUTO INDICATOR
The climate control unit has a self-diagnostic function. To run the self-diagnostic function, do the following:
1. Make sure the ignition switch is in LOCK (0).
2. Press and hold the AUTO and RECIRCULATION buttons, turn the ignition switch to ON (II), then release the AUTO and RECIRCULATION buttons.
3. All LCD segments come on for 2 seconds, then self-diagnostic function begins.
NOTE: The blower motor will run at various speeds when in the self-diagnostic mode, regardless of what the
panel is displaying. If there is any problem in the system, the temperature indicator will light up the segment (A through P) and AUTO indicator corresponding to the error. The temperature indicator will then alternate every second between
displaying ‘‘88’’ (all segments lit) and the error code segment (A through P) and AUTO indicator. To determine
the meaning of the DTC, refer to checking for DTCs.
 If there are no problems detected, the segments will not illuminate, and the system will appear to be turned off.
4. Turn the ignition switch to LOCK (0) to cancel the self-diagnostic function. After completing repair work, run the self-diagnostic function again to make sure that there are no other DTCs.

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)

How to clear the DTC
22-75
No DTCs detectedAll DTCs have been displayed
DTC detected
(the letter and four digit number on the left
represents the DTC, the right two digit is the
unit code.)
While in Test Mode 1, the DTCs which have been detected and stored individually by various B-CAN (Body-controller
Area Network) units, will be shown one by one on the odometer display when the communication between the MICU
and the gauge control module is normal. To scroll through the DTCs, press the select/reset button.
The unit that has stored the code can be identified by the number shown on the multi-information display.
MICU 10
Gauge control module 50
Climate control unit 51
HandsFreeLink control unit 94
Immobilizer-keyless control unit 96
While in Test Mode 1, press and hold down the SELECT/RESET button for more than 10 seconds.

Example: Error 1
The gauge control module acts as a gateway to allow both systems to share information, the gauge control module
translates information from B-CAN to F-CAN and from F-CAN to B-CAN.
The ECUs on the CAN circuit send messages to each other. If there is any malfunction on the network, the odo/trip
display on the gauge control module can indicate the error messages by entering the gauge self-diagnostic function
(see page 22-241).
 Error 1: There is a malfunction in the communication line between the gauge control module (tach) and the F-CAN.
 Error 2: There is a malfunction in the communication line between the gauge control module (tach) and the B-CAN.
