Auto Idle Stop Disable Conditions
The air conditioning system disables auto idle stop under any one of the following conditions. But the climate control unit enables auto idle stop when the blower motor is off.
- Outside air temperature sensor malfunction
|
- Humidity sensor malfunction
|
- Evaporator temperature sensor malfunction
|
- Climate control unit lost communication with gauge control module (coolant temp message)
|
- Climate control unit lost communication with gauge control module (VSP/NE message)
|
- Climate control unit malfunction
|
When the blower fan is in operation, the system applies the following conditions also.
- When the duration of auto idle stop is less than 10 second
|
- When the driver selects DEF mode manually
|
- When humidity in the car exceeds the upper limit of the permissible value that the climate control unit calculated
|
- Outside air temperature is less than -4°F (-20°C)
|
- When the mode position is in VENT or HEAT/VENT
- When the driver selects MAX COOL
- When the fan operates at the specified voltage of the terminal of the blower fan (FAN auto mode: 7 V or more/FAN manual mode: 8 V or more)
|
- When the mode position is in HEAT or HEAT/DEF
- When the engine coolant temperature is less than the specified value (ECON ON Mode: Less than 113°F (45°C)/ECON OFF Mode: Less than 158°F (70°C))
- Outside air temperature is less than 28°F (-2°C)
- When the driver selects MAX HOT
- When the fan operates at the specified voltage of the terminal of the blower fan (8 V or more)
