Description and operation

Description

According to driving environment and loading state of vehicle, headlamp 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 mounted on the rear center arm drives the actuator mounted on the headlamp after sensing the input signal for the static change of vehicle.

Headlamp beam is automatically operated by chassis tilt.

Operation

Operating Procedure

1.	Suspension angle change resulted from vehicle's load change.

2.	Sensor angle change.

3.	Microprocessor calculates necessary headlamp angle change amount.

4.	Sending a proper signal to headlamp leveling device and driving actuator.

Operating Condition

1.	Ignition on

2.	Low beam on

3.	On stop : If sensor lever change is 0.3° and above, headlamps are operated after max. 1.5 seconds.

4.	On driving : If vehicle velocity is over 4 km/h (2.48 mph), velocity change is not over 0.8 - 1.6 km/h (0.5 - 1.0 mph) per second, and loading condition is changed, then headlamps are operated.

Components

Auto headlamp leveling unit

(1)	Leveling unit & sensor

(2)	Sensor mounting bracket

(3)

Sensor linkage

•	Using a micro-processor, detect the operation level's change in mechanical angle and speed signal.

•	A device mounted on the rear center arm controls the actuator via internal control program.

Repair procedures

Inspection

1.	Ignition "ON".

2.	Turn on the headlamp switch.

3.	Check for operation. The aim of the headlamps should change smoothly when the headlamp leveling switch is operated.

4.	If the operation does not work well, inspect the connector and terminals to be sure they are all making good contact. If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system. If the terminals look OK, go to step 5.

5.	Substitute with a known-good headlamp assembly and check for proper operation.

Removal

1.	Disconnect the negative (-) battery terminal.

2.	Disconnect the headlamp leveling unit connector (A).

3.	Remove the headlamp leveling unit mounting link (A).

4.	Remove the headlamp leveling unit (A) after loosening the mounting bolts.

Installation

Install the headlamp leveling unit.

Tightening torque :

7 - 11 N·m (0.7 - 1.1 kgf·m, 5.1 - 8.1 lb·ft)

2.	Install the headlamp leveling unit mounting link.

3.	Connect the headlamp leveling unit connector.

4.	Connect the negative (-) battery terminal.
