What does this fault code mean?
The module's programmable memory (EEPROM) holds too little or wrong data, which means it is incorrectly programmed. The fault code cannot be cleared by hand and disappears once programming is complete. The headlamps stay in their lowest position until then.
Possible causes
- The control module is incorrectly programmed
What you can do
- 1Do not try to clear the code yourself: it disappears by itself when programming is complete
- 2Have a workshop reprogram the control module, since programming is a workshop task
- 3If reprogramming does not help, have a workshop replace the control module and calibrate it
- 4After the work, check that the fault code has gone
Symptoms you may notice1
- The headlamp motor does not work
What the fault can affect1
- The headlamps are set to their lowest position
