1. Connect the WDS or equivalent to the DLC-2.

2. Shine a 60 W incandescent light from a distance of approx. 100 mm {3.9 in} directly onto the solar radiation sensor.

  Note

  • If incandescent light is not shone on the solar radiation sensor, the climate control unit determines a malfunction and indicates DTC "B1260, B1261".

3. Verify if any DTCs are displayed.

  • If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection.

4. After completion of repairs, clear all DTCs from memory. (See After Repair Procedure.)

## After Repair Procedure

1. Connect the WDS or equivalent to the DLC-2.

2. Using the WDS or equivalent, clear DTCs from the PCM memory.

3. Turn the ignition switch off.

4. Perform the DTC inspection again and verify that no DTCs are displayed.
