Volvo models this fault code applies to
This fault code has different meanings depending on model, model year or engine. Select the meaning that applies to your car.
Applies to the following models:
5 modelsS60 (2001–2009), S80 (1999–2006), V70 (2000–2008), V70 XC / XC70 (2001–2007), XC90 (2003–)
What does this fault code mean?
The signal from the air distribution knob is faulty. This is probably caused by a defective potentiometer, or by a short to supply voltage or ground in it. Air distribution then does not work as it should, because the control module does not know which setting you have chosen.
Possible causes
- Defective potentiometer
- Potentiometer shorted to live voltage or ground
What you can do
- 1With the ignition on, move the air distribution selector between its positions and check that the airflow changes
- 2If the fault returns, have a workshop check the control and its connector
- 3If the fault is permanent the climate control module must be replaced, since the potentiometer cannot be replaced separately. Have a workshop do this
- 4If you have a diagnostic tool, follow the control value in live data while you turn it between its end positions
Symptoms you may notice2
- The air distribution knob does not work
- Buttons and control knobs on the centre console (climate) do not work, work reduced or work incorrectly
General guidance for car owners. Diagnosis on the car can point to a different cause.
