Description and operation
Dscription

[Air conditioning type]

The cooling fan operates in 2 stages (HIGH/LOW). The engine control module (ECM) controls the cooling fan according to the coolant temperature, vehicle speed and A/C operation.

[Non-Air conditioning type]

The cooling fan operates in 1 stage (HIGH). The engine control module (ECM) controls the cooling fan according to the coolant temperature, vehicle speed and A/C operation.
