Headlamp Alignment Actuator: Testing and Inspection

Inspection

Initialization and diagnosis sequence by using diagnostic equipment
Below content summarize the procedure for A/S using Diagnostic equipment

Download parameter
1. Select "AFLS" menu after selecting "GENESIS" of vehicle lists.




2. Select "Parameter download" menu for define a characteristic of vehicle.








3. Select "Air suspension not apply" if vehicle has a standard suspension




4. Select "Air suspension apply" if vehicle has a Air suspension




5. When "Parameter download" is done,display below.





System calibration

CAUTION:
This menu is applied only if vehicle has a Steel suspension

1. Select "AFLS" menu after selecting "GENESIS" of car lists.
2. Select "Sensor initializing-Non ECS" if vehicle has a Steel suspension




3. When "System calibration" is done,display below.




4. When "System calibration" is not done,display below.





Actuator test
When it replace H/Lamp Unit, it necessarily check up by operating actuator test.
1. Select "AFLS" menu after selecting "GENESIS" of car lists.
2. Select "Actuator test"




3. Select DBL or HLL test by using F1 key
4. In case select BOTH DBL ACTUATOR DRIVE TO MAPOS(swivelling)
In case select F1 key : drive to max position CCW direction (15°)
In case select F2 key : back to initial position








5. In case select BOTH DBL ACTUATOR DRIVE TO MAPOS (Leveling)
In case select F1 key : drive to max position upper side
In case select F2 key : back to initial position









AFLS Fail-safe function
If the error condition of AFLS occurred during system operation, the system have to fail-safe reaction for prevent dazzling of opposite side driver

AFLS Fail-safe Index


















AFLS Setting Procedure
When it replace AFLS ECU, H/Lamp Unit, Height sensor, it operates in setting procedure by using Diagnostic equipment following below.
Parameter is composed of three state (Air-suspension,Steel-suspension,Delivery state)
When AFLS setting procedure operate, necessarily confirm suspension type and then download parameter.




** DTC : Diagnostic Trouble Code
DBL : Dynamic bending Light
HLL : Head Lamp Leveling

Vehicle condition while AFLS setting
1. Vehicle on an even surface
2. No vehicle movement
3. Gear position in P & N
4. Ignition switched on & Engine RPM > 500RPM
5. Diagnostic equipment connected
6. ALL ECUs on CAN mounted and activated
7. Battery voltage > 10.5 V ( ECU supply to be ensured)
8. Light switched
9. AFLS on (Don't push AFLS OFF switch )

Action in case of download wrong parameter
1. In case Steel suspension vehicle downloaded Air- suspension parameter
-> B1638 (Air-Sus. CAN Signal Timeout) occurred
2. In case Air- suspension car downloaded Steel suspension parameter
-> B1907 (FRT Sensor signal Fault), B1909 (Rear Sensor signal Fault) occurred
3. Solution
A. Download Delivery Parameter
B. check up B1661(Parameter missing)
C. Ignition OFF
D. Ignition ON & Engine RPM > 500RPM
E. Download matching Parameter (Steel & Air suspension)
**In case download steel suspension parameter, Calibration have to operate up to setting procedure
