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 a vehicle.

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

3.
Select "Non Air suspension" if vehicle has a standard suspension

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

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

System Calibration
   
This menu is applied only if vehicle has a Steel suspension
1.
Select "AFLS" menu after selecting a vehicle.
2.
Select "Sensor initializing-Non ECS" if vehicle has a Steel suspension

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

4.
When "System calibration" is not done,display as belows.

Actuator Test
When it replace H/Lamp Unit, it necessarily check up by operating actuator test.
1.
Select "AFLS" menu after selecting a vehicle.
2.
Select "Actuator test"

3.
Select DBL or HLL test by using "Start" button.
4.
In case select BOTH DBL ACTUATOR DRIVE TO MAX POS(swivelling)
In case select "Start" button : drive to max position right direction (15°)
In case select another item : back to initial position

5.
In case select BOTH HLL ACTUATOR DRIVE TO MAX POS (Leveling)
In case select "Start" button : drive to max position upper side
In case select another item : 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 Setting Procedure
When it replace AFLS ECU, H/Lamp Unit, Height sensor, it operates in setting procedure by using Diagnostic equipment following belows.
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.

x 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.
AUTO light switch is on.
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
> B1953 (Leveling 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 Paratmer (Steel & Air suspension)
xIn case download steel suspension parameter, Calibration have to operate up to setting procedure
