If it does not, check the fuses, cooling fan relays, ecm and cooling fan, and then check for an open circuit between the cooling fan relay and engine coolant temperature sensor.
- Reconnect the engine coolant temperature sensor connector.
- Check cooling fan operation at high temperatures (above 96°c (205°f))
- Start the engine, and then raise the coolant temperature to above 96°c (205°f).
Hint:
Coolant temperature is the value detected by the engine coolant temperature sensor on the cylinder head.
