DTC 02 |
Solar radiation sensor (present malfunction) |
|---|---|
|
DETECTION CONDITION
|
• Solar radiation signal input from the solar radiation sensor is 116 W/m2 or less or 1,453 W/m2 or more.
|
|
POSSIBLE CAUSE
|
• Low-light intensity on solar radiation sensor (circuit is normal).
• Solar radiation sensor malfunction
• Open or short circuit in wiring harness between climate control unit and solar radiation sensor
• Climate control unit malfunction
|
 |
|
Diagnostic Procedure
|
STEP |
INSPECTION |
ACTION |
|
|---|---|---|---|
|
1
|
VERIFY DTCs
• Shine an incandescent light (approx. 60 W) directly on the solar radiation sensor from a distance of approx. 100 mm {3.94 in}.
• Verify DTCs.
• Is DTC 02 output?
|
Yes
|
Go to the next step.
|
|
No
|
DTC troubleshooting completed.

2
|
INSPECT SOLAR RADIATION SENSOR CONNECTOR CONDITION
• Turn the ignition switch to the LOCK position.
• Remove the solar radiation sensor.
• Inspect the connector and terminals (corrosion, damage, pin disconnection).
• Are the connector and terminals normal?
|
Yes
|
Go to the next step.
|
|
No
|
Repair/replace the connector or terminal.
After repair procedure, go to Step 8.

|
3
|
INSPECT SOLAR RADIATION SENSOR
• Inspect the solar radiation sensor.
• Is the solar radiation sensor normal?
|
Yes
|
Go to the next step.
|
|
No
|
Replace the solar radiation sensor.
Replace the solar radiation sensor, then go to Step 8.
|

|
4
|
INSPECT SOLAR RADIATION SENSOR FOR OPEN CIRCUIT
• Turn the Ignition switch to the ON position.
• Measure the voltage of the following terminals.
• Is the voltage approx. 5 V?
|
Yes
|
Go to the next step.
|
|
No
|
Go to Step 7.
|
||
|
5
|
INSPECT SOLAR RADIATION SENSOR FOR OPEN CIRCUIT
• Turn the ignition switch to the LOCK position.
• Disconnect the climate control unit connector.
• Inspect the wiring harness for continuity between solar radiation sensor connector terminal B and climate control unit connector terminal P.
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Repair/replace the malfunctioning vehicle wiring harness.
After repair procedure, go to Step 8.
|
||
|
6
|
INSPECT SOLAR RADIATION SENSOR FOR SHORT CIRCUIT TO GROUND
• Inspect the wiring harness for continuity between the solar radiation sensor connector and body ground.
• Is there continuity?
|
Yes
|
Repair/replace the malfunctioning vehicle wiring harness.
After repair procedure, go to Step 8.
|
|
No
|
Go to the next step.
|
||
|
7
|
INSPECT CLIMATE CONTROL UNIT CONNECTOR CONDITION
• Disconnect the climate control unit connector.
• Inspect the connector and terminals (corrosion, damage, pin disconnection).
• Are the connector and terminals normal?
|
Yes
|
Go to the next step.
|
|
No
|
Repair/replace the malfunctioning vehicle wiring harness, connector, or terminal.
After repair procedure, go to the next stop.
|
||
|
8
|
VERIFY THAT SAME DTC IS NOT OUTPUT AGAIN
• Reconnect the disconnected connectors.
• Shine an incandescent light (approx. 60 W) directly on the solar radiation sensor from a distance of approx. 100 mm {3.94 in}.
• Verify DTCs.
• Is DTC 02 output?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction does not recur, go to the next step.
• If the malfunction recurs, replace the climate control unit.
|
|
No
|
Go to the next step.
|
||
|
9
|
VERIFY THAT NO OTHER DTCs ARE PRESENT
• Verify other DTCs displayed.
• Are any other DTCs output?
|
Yes
|
Perform the corresponding DTC inspection.
|
|
No
|
DTC troubleshooting completed.
