Toyota Sienna Service Manual: Precaution

NOTICE:
  • 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 intelligent tester indicates a very high coolant temperature.

– The intelligent tester 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
