HVAC System (Diagnostics): List

NOTE: If not equipped (depending on destination area or vehicle equipment condition), some items are not displayed.

Active test items	Range	Contents	Execution condition
In-vehicle Air Temperature setting	-72.47 - 193.82°C	Set in-vehicle sensor readings. Adjusting the in-vehicle sensor value to use for A/C control is useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Ambient Air Temperature Setting	-40 - 80 °C	Set ambient sensor readings. Adjusting the ambient sensor value to use for A/C control is useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Quantity of Sunload Setting	0 - 4448 W/m²	Set sunload sensor readings. Adjusting the sunload sensor value to use for A/C control is useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Heater Water Temperature Setting	-40 - 214 °C	Set coolant temperature sensor readings. Adjusting the coolant temperature sensor value to use for A/C control is useful for reproduction test in faulty events.	Engine ON
AUTO switch mode setting	ON	Transmit ON signal of AUTO switch contact. By operating A/C with the signal, it is possible to judge whether the control is faulty or the switch (A/C control panel) is faulty.	Ignition switch ON NOTE: Engine ON is recommended.
Air mix door actuator target open (driver's side)	0 - 100 %	Set the driver's seat air mix door actuator opening angle. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Air mix door actuator target open (passenger's side)	0 - 100 %	Set the passenger's seat air mix door actuator opening angle. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Fresh/Rec Air Dr Act Trgt Open Angle	0 - 100 %	Set the intake door actuator opening angle. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Mode Door Actuator Opening Angle Target	0 - 100 %	Set the mode door actuator opening angle. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Blower Fan Level Setting	0 - 100 NOTE: Input up to 255 is possible, but 100 - 255 is the same.	Set the blower fan level. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended. Compressor OFF is needed to set the level to 0.
A/C Change Setting	ON/OFF	Set the compressor operation request. Useful for reproduction test in faulty events. NOTE: Active test error may occur for the protection control of the engine or compressor.	Engine ON Blower ON
Rear Defogger Setting	ON/OFF	Transmit the rear defogger switch contact signal. By operating A/C with the signal, it is possible to judge whether the control is faulty or the switch (A/C control panel) is faulty.	Ignition switch ON NOTE: Engine ON is recommended.
Variable Flow Change Solenoid Duty	0 - 100 %	Set Duty value of variable flow change solenoid valve. Useful for reproduction test in faulty events. NOTE: The setting value may not be obtained due to A/C circuit protection.	Engine ON Compressor ON Blower ON
PTC steps	0 - 3	Set PTC level. Useful for reproduction test in faulty events. NOTE: The setting value may not be obtained due to power supply circuit protection.	Engine ON Blower ON
Rear In-vehicle Air Temperature setting	-72.47 - 193.82°C	Set rear in-vehicle sensor readings. Adjusting the rear in-vehicle sensor value to use for A/C control is useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Rear AUTO Switch Mode setting	ON	Transmit ON signal of rear AUTO switch contact. By operating A/C with the signal, it is possible to judge whether the control is faulty or the switch (A/C control panel) is faulty.	Ignition switch ON NOTE: Engine ON is recommended.
Air mix door Actuator Target Open (Rear Seat)	0 - 100 %	Set the rear seat air mix door actuator opening angle. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Rear Mode Door Actuator Opening Angle Target	0 - 100 %	Set the rear mode door actuator opening angle. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended.
Rear Blower Fan Level	0 - 100 NOTE: Input up to 255 is possible, but 100 - 255 is the same.	Set the rear blower fan level. Useful for reproduction test in faulty events.	Ignition switch ON NOTE: Engine ON is recommended. Compressor OFF is needed to set the level to 0.
