What does this fault code mean?
The fault code is set in a new control module that has not yet been calibrated. It cannot be cleared by hand and disappears automatically once the calibration is complete. The headlamps stay in their lowest position until then.
Possible causes
- The control module is not calibrated
What you can do
- 1Switch on the dipped beam and start the car, since the control module only communicates with the dipped beam on cars without automatic dipped beam
- 2Have a workshop calibrate the control module, since calibration is a workshop task
- 3After calibration, check that the fault code has gone
Symptoms you may notice1
- The headlamp motor does not work
What the fault can affect1
