Hva betyr feilkoden?
The code is event controlled, which means it is an information code and does not show a fault in the engine control module. It is set when the cooling fan needs to run at very high speed for a long time, for example in queues of traffic when it is very hot. The code clears when the conditions no longer apply and does not need to be erased.
Mulige årsaker
- Very high outside or engine temperature, so that the cooling fan has to run at high speed for a long time, for example in queues of traffic
Hva du kan gjøre
- 1Check that the radiator grille is not blocked by dirt or leaves, as the fan then has to work harder.
- 2Check that the cooling fan starts when the engine gets warm, and that it keeps running for a while after the engine is switched off.
- 3If you have a diagnostic tool, read the coolant temperature in live data when the engine is warm, and check whether the cooling fan runs as the temperature rises.
- 4If the code comes back even during normal driving, have a workshop check the cooling fan and its control.
Symptomer du kan merke1
- The cooling fan does not work
