ALP 1No dialogue with the computer
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.

ALP 2No correction of the height of the one or both headlights
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).

ALP 3Glare, or beam too high
NOTESOnly refer to this customer complaint after a complete check with the diagnostic tool.
Check that headlights are mounted correctly.
Check that the right-hand and left-hand headlights light at the same level.
If the headlights differ in height, adjust the headlights manually.
Check the condition of system mechanical components (sensor mounting, links).
Check whether the initial front and rear heights PR032 Reference front height and PR033 Reference rear
height are similar.
If there is a major difference between these two parameters, perform a computer calibration (CF001 Computer
calibration described in the Configurations and Programming section).
Run actuator command AC012 Check actuator high and low position.
If the light beam moves: adjust the headlights manually.
If the light beam does not move:
Check that the adjustment motors are actuated when the command is run (motor noise + vibration).
If the motors are actuated but the beam does not move, check the condition of the adjustment motor/headlight
coupling rods. Replace the faulty headlight(s).

ALP 4The left-hand and right-hand dipped headlight beams do not light at the same
height
NOTESOnly refer to this customer complaint after a complete check with the diagnostic tool.
Check that headlights are mounted correctly.
Check that the right-hand and left-hand headlights light at the same level.
If the headlights differ in height, adjust the headlights manually.
Check the condition of system mechanical components (sensor mounting, links).
Check whether the initial front and rear heights PR032 Reference front height and PR033 Reference rear
height are similar.
If there is a major difference between these two parameters, perform a computer calibration (CF001 Computer
calibration described in the Configurations and Programming section).
Run actuator command AC012 Check actuator high and low position.
If the light beam moves: adjust the headlights manually.
If the light beam does not move:
Check that the adjustment motors are actuated when the command is run (motor noise + vibration).
If the motors are actuated but the beam does not move, check the condition of the adjustment motor/headlight
coupling rods. Replace the faulty headlight(s).
