SOLAR VENTILATION SYSTEM OPERATION CHECK

SOLAR VENTILATION SYSTEM OPERATION CHECK

1. Inspection of Voltage Generated by Moon Roof Glass Assembly (Solar Panel)

   
   

   1. Park the vehicle in a location with a stable temperature and a sufficient amount of sunlight, and leave the vehicle as is for approximately 10 minutes.

      Note

      To ensure stable generation of voltage by the moon roof glass assembly (solar panel), make sure to park the vehicle in a location where the system operation requirements are satisfied.

      Tech Tips

      The solar ventilation system operates only when the generated voltage is 10 V or higher. Therefore, make sure to park the vehicle where the system operation requirements are satisfied. This will allow the moon roof glass assembly (solar panel) to generate a voltage of 10 V or higher.

      System Operation Requirements

      Item	Condition
      Amount of sunlight	A sufficient amount of sunlight is received by the moon roof glass assembly (solar panel). (The amount of sunlight on a cloudless day between 11:00 and 14:00 is typically sufficient for operation.)
      Moon roof glass assembly (solar panel) status	The moon roof glass assembly (solar panel) is not in the shade
      	No fallen leaves or dirt is present on the moon roof glass assembly (solar panel)
      Ambient temperature	20 to 40°C (68 to 104°F)

   2. Connect the intelligent tester to the DLC3.

   3. Turn the power switch on (IG).

   4. Turn the intelligent tester on.

   5. Enter the following menus: Body / Air Conditioner / Data List.

      Air Conditioner

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Solar Voltage	Solar panel voltage / 10V les, 10V-11V, 11V-12V, 12V-13V, 13V-14V, 14V-15V, 15V-16V, 16V-17V, 17V-18V, 18V-19V, 19V-20V, 20V-21V, 21V-22V, 22V-23V or 23V ovr	Actual generated voltage displayed	System operation requirements are met Click here.

      Tech Tips

      If the Data List items related to the solar ventilation system are not displayed, the following conditions are suspected:

      
      

      • The voltage generated by the moon roof glass assembly (solar panel) is less than 7 V Click here.

      • There is a communication error between the solar ventilation ECU and A/C amplifier Click here.

2. Operation Check

   
   

   1. Check that the Solar Voltage value in the Data List is 10 V or higher.

   2. Turn the solar ventilation switch on.

   3. Turn the power switch off.

   4. Check that the blower motor operates 10 minutes after the power switch is turned off.

      Tech Tips

      
      

      • The inlets will be changed to fresh air mode and the outlets will be changed to face mode approximately 1 minute after the power switch is turned off.

      • Inlet and outlet modes will remain unchanged when the solar ventilation switch is turned on after the power switch is turned off.

      • When the moon roof glass assembly (solar panel) is generating high voltage, a noise may occur when the blower motor starts operating. This noise does not indicate a malfunction.
