ON-BOARD DIAGNOSTIC
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.)

Handling Refrigerant
Avoid breathing air conditioning refrigerant or lubricant vapor. Exposure may irritate eyes, nose and throat. Also, due to environmental concerns, we urge use of recovery/recycling/recharging equipment when draining R-134a from the air conditioning system. If accidental system discharge occurs, ventilate work area before resuming service. 
Do not perform pressure test or leak test for R-134a service equipment and/or vehicle air conditioning system using compressed air. Some mixtures of air and R-134a have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or property damage. Additional health and safety information may be obtained from refrigerant manufacturers. 
Do not allow the refrigerant to leak near fire or any kind of heat. A poisonous gas may be generated if the refrigerant gas contacts fire or heat such as from cigarettes and heaters. When carrying out any operation that can cause refrigerant leakage, extinguish or remove the above-mentioned heat sources and maintain adequate ventilation. 
Handling liquid refrigerant is dangerous. A drop of it on the skin can result in localized frostbite. When handling the refrigerant, wear gloves and safety goggles. If refrigerant splashes into the eyes, immediately wash them with clean water and consult a doctor.
