Headlight lighting distance adjustment failure, headlight distance adjustment fault lamp how to elim

Hello, there are many reasons for this failure, first of all, the headlight lighting sensor and related lines, first of all, you need to go to the maintenance plant to detect the relevant fault code with a computer, and then check and repair according to the fault code prompt, I hope it can help you, I wish you a happy car [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

One night, park your car next to a white wall. Keep the front of the car as perpendicular to the wall as possible, preferably at a distance of about 10 meters. Then turn the headlights on and cover one of the lights with a thick cloth so that you can adjust the headlights on both sides one by one.

At this time, it is better to not load the load in the car, so that the lights are more balanced when adjusting. Otherwise, if the rear of the car is heavy, the lights will shoot upwards, and if the car leans forward, the lights will shine downwards. It is advisable to find a friend to sit in the car, so that you can not only maintain the proper load, but also maintain the level of the spotlights when you are driving.

When the lights are turned on, the projection of the lights on the wall is recorded with chalk, and the left and right lights should be kept at an equal distance from the central axis of the car. If there is an outward or inward deviation, it must be adjusted with a screwdriver according to the instructions in the car's manual. As for the height of the light beam, the right light should be completely horizontal, while the left light should be raised by 10 cm.

Note that the headlights should not be adjusted too high, as this will dazzle the eyes of the opposite driver and increase the presence of risk factors.

In addition to the height, the width of the headlights can also be adjusted, and the right headlight beam can be adjusted slightly to the right, so that in the rain and fog with extremely low visibility, the right side of the road surface will be seen more clearly to ensure the safety of driving.

Hello, it is a pleasure to serve you and give you the following answer: the failure occurred and the cause is likely to be a malfunction of the controller of the headlight distance teasing knuckle system. Workaround:

1. Check whether the power cord is in good contact, if the contact is not good, you need to replace the wiring. 2. Check whether the indicator light on the controller of the headlight distance adjustment system is normal, if the indicator light is not on, it may be that the controller is faulty and the controller needs to be replaced. 3. Check whether the sensor of the headlight distance adjustment system is normal, if the sensor fails, the sensor needs to be replaced.

4. If the previous steps have not solved the fault, you need to check whether the circuit of the headlight distance adjustment system is normal, and if there is a problem with the circuit, you need to replace the circuit board. 5. If the above steps do not solve the fault, you need to check whether the software of the headlight distance adjustment system is normal, if there is a problem with the software, you need to replace the software. The above is a brief introduction to how to eliminate the headlight distance adjustment fault lamp, I hope it can help you.

The car came before the big one.

Under the influence of trunk load, long-term vibration, high and low road conditions, etc., the lamp will cause the irradiation direction to deviate from the standard direction, and the function of the light regulator DAO is to adjust the headlight illumination direction from the deviation direction to the standard direction, so as to improve the lighting effect of the headlights.

At present, the light regulator mainly has two modes: manual and automatic: the manual mode is mainly composed of a headlight adjusting motor and a manual switch, the headlight adjusting motor is at the front headlight, the control part is in the cab, and there is a manual switch on the dashboard, which is adjusted by the driver according to his own needs; The automatic type is composed of a headlight adjustment motor, a controller and two level sensors, and the level sensors are installed at the front and rear ends of the body respectively, mainly detect the height of the automobile chassis to the ground, and transmit the height difference to the controller in the form of an electrical signal, and the controller controls the headlight adjustment motor after comparison and calculation, so as to complete the automatic adjustment function of the headlight.

Working process: adjusting switch 1 is installed on the automobile dashboard, and generally has 5 gears respectively and the default gear (in addition, there is stepless adjustment type); Actuator is headlight regulator 2, is installed in automobile headlamp (or headlamp outside); The headlamp adjusting screw rod 3 is pushed to the outside of the headlamp reflective surface, and the telescopic movement is carried out with the section screw 3 of the adjusting headlight adjuster of switch 1 during work, and the headlamp reflective surface movement is driven to adjust the height of the reflected light focal length, so as to achieve the effect of adjusting the headlight.

First of all, you need to prepare a tool to adjust the lights. One small wheel, one black stick, and one hexagonal hood. Then proceed to the following operation process:

1. Open the left front door of the car and sit in the main driver's seat, take out the car key and open the car key door. As shown in the picture, it would be nice if the dashboard was lit up. Second, the dashboard is lit up, find the light button on the car.

3. Adjustment method of headlamp height: 1. Park the car at a distance of meters from the wall, then turn on the lamp, and then adjust the illumination position of the lamp according to the position of the lamp on the wall. If the model with the headlamp height adjustment switch needs to adjust the height manually, the headlamp height adjustment knob must be before adjusting the headlamp"0"；2. In order to set up the standard lines of spine socks on the wall, it is necessary to measure the position of the headlights at these three distances.

Distance a is the distance from the center of the low beam to the center axle of the vehicle. Distance b is the distance from the center of the high beam to the central axis of the vehicle, and distance c is the distance from the center of the low beam to the ground. 3. The position of the adjusting lamp is achieved by adjusting the adjustment knob of the corresponding position behind the headlamp.

Depending on the model, the parts that should be adjusted and the tools used are different, and it needs to be decided according to the specific model. Before adjusting, lean the light against the wall to observe whether the light is misaligned or too low; 4. If you find this difficult, the simple way to judge is to let a person with a height of 180 cm stand in front of the car, and the relationship between the low beam should not be higher than the person's buttocks. If it's too high, turn the adjustment knob to adjust.

The solution to the problem of poor headlight height adjustment is as follows:

1. Park the car at a position of meters away from the wall to turn on the lights, adjust the illumination position of the lights according to the position of the lights on the wall, and adjust the headlight height adjustment knob to the position before adjusting the headlights;

2. To measure the three distances of the headlight position in advance, distance A is the distance from the center of the low beam to the axis of the car, distance B is the distance from the center of the high beam to the axis of the car, and the distance C is the distance from the center of the low beam to the ground;

3. Adjusting the position of the light is achieved by adjusting the adjustment knob of the corresponding position behind the headlight.

Summary. Hello, happy to answer your questions.

The irradiation distance of automobile headlights is usually 80-120 meters, and the irradiation distance of low-beam is 10-30 meters. According to GB7258-1997 "Technical Conditions for Motor Vehicle Operation Safety", the luminous intensity of the headlamp and the beam irradiation position are specified as follows: 1. The headlamp beam irradiation position requires that the motor vehicle (except for the tractor for transportation) when inspecting the low beam irradiation position of the headlamp, the headlamp is 10m away from the screen, and the height of the corner or midpoint of the beam light and dark cut-off line should be the height of the reference center of the headlamp, the same below). The horizontal position to the left and right shall not exceed 100mm2, the adjustment of the high-beam single beam lamp of the four-lamp headlamp, the height of the beam center on the screen is required to be above the ground, and the horizontal position requires that the left light deviation shall not be greater than 100mm, and the right deviation shall not be greater than 170mm; The right light to the left or to the right shall not be greater than 170mm3, and the low beam beam should be adjusted when the motor vehicle is equipped with high beam and low beam double beam.

For lights that can only adjust the high beam monobeam, adjust the high beam single beam.

It's my Wuling Hongguang S1 last year to repair a previous light, and then hit the low light, and it was a corner when it was illuminated, which was very unpleasant.

I think this is a blind spot that will have a blind spot, dear. I also drive and sometimes the low beam is uncomfortable.
