Cooling Fan System: Precaution
NOTE:
- When the ignition switch is turned off and the engine temperature is high, the cooling fans may operate for approximately 3 minutes.
- After turning the ignition switch off, keep hands and objects away from the fans when they are operating.
HINT:
If all of the following are met for a certain period of time during a few minute period immediately before the engine is stopped, the electric fans will continue to operate for 3 minutes after the engine is stopped. This is performed to ensure restartability and stabilize idle speed.
- The Techstream indicates a very high coolant temperature.
- The Techstream indicates a high outside air temperature.
- The vehicle has been driven under high load (driving on an uphill or equivalent).
The following sensors are used for this control:
- Coolant temperature sensor
- Outside air temperature sensor
- MAF sensor
- Vehicle speed sensors
