NOTESOnly refer to this customer complaint after a complete check with the diagnostic tool.
Check the 1K (5A) fuse of the passenger compartment relay and fuse box.
Replace it if necessary.
Turn on dipped-beam headlights.
If the bulbs light but the system does not perform initialisation and no communication is possible, perform the
following checks:
Remove the timed power supply 40A relay A located in the passenger compartment fuse and relay box.
Check the condition of the connections and repair if necessary.
Measure the following resistance values:
–Power circuit: Resistance between tracks 85 and 86 of the relay.
If the resistance is not 65 ± 5 ΩΩ Ω Ω
, replace relay A.
–Control circuit: Resistance between tracks 30 and 87A of the relay.
If the resistance is not approximately 1 ΩΩ Ω Ω
, replace relay A.
Check the battery voltage and carry out the operations necessary to obtain a suitable voltage (9.5 V < battery
voltage <14.4 V).
Check for:
a + 12 V supply before ignition on track 16 of the diagnostic socket,
a + 12 V supply after ignition on track 1 of the diagnostic socket,
earth on tracks 4 and 5 of the diagnostic socket.
Repair if necessary.
If the fault is still present, contact the Techline.

whatever the vehicle load
NOTESOnly refer to this customer complaint after a complete check with the diagnostic tool.
Confirm that initialisation is performed when the dipped headlights are switched on.
If it is not, the actuators or a circuit component may be defective.
Check the condition of fuse F1K (5A) located in the vehicle's glovebox.
Repair if necessary.
Run command AC012 Check actuator high and low position to find out which headlight is faulty.
Check for mechanical blockage of the headlight (ball joint popped out, reflector stuck, actuator seized).
Make sure that the sensors are properly positioned and mounted on the body, and check the condition
of the linkage.
If all the checks described above fail to solve the fault, replace the faulty adjustment motor(s).
