  3. Shine an 100 W incandescent light or the like on sunload sensor (1) 100 mm (3.94 in.) high from the sensor
    NOTE: Do not use fluorescent light, LED and etc. for this check. HVAC control module detects "Sun Load Sensor Circuit Malfunction" and the DTC is displayed on scan tool because light volume is insufficient.
