Operation Check

HEATING / AIR CONDITIONING: SOLAR VENTILATION SYSTEM: OPERATION CHECK

1. SOLAR VENTILATION SYSTEM OPERATION CHECK

(a) 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.

NOTICE:
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 conditions reference table are satisfied.

HINT
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 conditions reference table are satisfied. This will allow the moon roof glass assembly (solar panel) to generate a voltage of 10 V or higher.

System Operation Conditions Reference Table





(2) Connect the Techstream to the DLC3.

(3) Turn the power switch on (IG).

(4) Turn the Techstream on.

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

Air Conditioner





HINT
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 Solar Ventilation ECU Power Source Circuit.
* There is a communication error between the solar ventilation ECU and A/C amplifier Communication Circuit Between Solar Ventilation ECU And A/C Amplifier.

(b) 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.

HINT
* 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.
* For details of the solar ventilation system control, refer to System Description System Description.

2. TEST MODE

HINT
In test mode, the solar ventilation ECU operates the blower motor while the power switch is on (IG). The state of the solar ventilation switch received by the solar ventilation ECU and the status of duty output from the solar ventilation ECU to the blower motor can be checked.

(a) Test Mode Procedure

HINT
Perform the operation according to the following procedure with the power switch on (IG) and the solar ventilation switch off.

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

(2) With the power switch on (IG), turn the power switch from off to on (ACC) to on (IG) 3 times within 5 seconds (on (IG) -> off -> on (ACC) -> on (IG) -> off -> on (ACC) -> on (IG) -> off -> on (ACC) -> on (IG)).

HINT
Operate the power switch 9 times.

(3) Turn the solar ventilation switch from off to on 3 times within 3 seconds (off -> on -> off -> on -> off -> on) of operating the power switch.

HINT
Operate the solar ventilation switch 5 times.

(4) Check that test mode is activated and the blower motor rotates at a constant speed.

HINT
* When the solar ventilation switch is turned off, the blower motor will stop and when the solar ventilation switch is turned on, the blower motor will operate.
* When the power switch is turned off, the solar ventilation system returns to normal control.
