Hyundai i-30: Auto Head Lamp Leveling Device / Auto Head Lamp Leveling Unit
Schematic diagrams
Description and operation
According to driving environment and loading state of vehicle, head lamp lighting
direction is changed to keep the driver's visibility range and to protect the
driver's vision from glare, aiming at safety driving.
Sensor integrated ECU mounting on the rear center arm drives the actuator mounting
on the head lamp since sensing the input signal following the vehicle's statically
changes.
Head lamp beam is automatically operated by chassis tilt.
Operating Procedure
1. |
Suspension angle change resulted from vehicle's load change.
|
3. |
Microprocessor calculates necessary head lamp angle change amount.
|
4. |
Sending a proper signal to head lamp leveling device and driving actuator.
|
Operating Condition
3. |
On stop : If sensor lever change is 0.3° and above, head lamp is operated
after max. 1.5 sec.
|
4. |
On driving : If vehicle velocity is over 4km/h(2.48mile/h), velocity
change is not over 0.8-1.6km/h(0.5 - 1.0mile/h) per second, and loading
condition is changed, then head lamp is operated.

|
Repair procedures
2. |
Turn on the head lamp switch.
|
3. |
Check that the aim of the head lamp changes smoothly when the head lamp
leveling device switch is turned on.
|
4. |
If it does not operate well, check the connector and terminals to make
sure that they are connected.
If the terminals are bent, loose or corroded, repair them as necessary,
and recheck the system.
If the terminal is in good condition, move to the step 5.
|
5. |
Replace the head lamp assembly and check for proper operation.
|
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Disconnect the head lamp leveling unit connector (A).
|
3. |
Remove the head lamp leveling unit (B) after loosening the mounting
bolts and nut.
|
1. |
Install the head lamp leveling unit.
|
2. |
Reconnect the head lamp leveling unit connector.

screen.
|
3. |
To perform functional test on AHLS outputs, select "Actuation Test".
|
4. |
Select " Parameter setting & Zero position Initial".
|
5. |
Confirm that AHLS operate forcefully in "Head lamp leveling" menu.
|
6. |
To check the DTC of the head lamp leveling system, select "Diagnostic
trouble codes"
