There is no problem with the failure of the automatic headlights

LaCrosse automatic headlight problem 1The reaction is slow, and the headlights are activated after about 5 seconds after entering the dark. I have driven Camry, BMW and other cars, and the reaction time of the automatic headlights does not exceed 1 second, so there is no such problem?

2.When you go into a darker place, such as in the afternoon near dusk, or in broad daylight and turn on in the shade of a tree, the headlights will activate after a while. Often at dusk, I see only the headlights of the Regal car on in the traffic coming and going.

It seems that it can't be adjusted, and I've asked for 4s. The automatic headlights that have been turned on, is the auto gear, this time the airport parked the car, because the position is small, the cab door can not be opened, it came out of the co-pilot, the headlights have been on, there is no automatic shutdown, and so I have returned from traveling, there has been no power for a long time, looking for a car to take the electricity, the result is sequelae, hanging D gear, stepping on the brakes, the shaking is particularly serious, the idle speed is stable, the reverse is also shaking, and the feeling of shaking is similar to the feeling of manual gear offshifting.

There are several situations of automatic headlight failure, engine idle jitter, gear start jitter, cold start, three-way catalytic temperature is not enough, and the most common reason for car shake caused by serious engine carbon deposition is that the throttle valve is too dirty or the fuel injector is too much carbon deposit, because the gasoline adsorbed on the carbon deposit after the car is sucked into the cylinder by the engine for combustion, and the combustible mixture of the engine is dilute and thick, resulting in idle jitter after cold start. Solution: Siyoupu cleans the oil circuit and checks whether the idle motor has carbon deposits and should be cleaned.

The light sensor is located in the middle front of your car's center console. Let's see if it's blocked. Some riders buy lightproof pads for the car's central console. I blocked the light sensor. So the lights are on both day and night.

Hello, this automatic headlight is generally a sensor failure, or a foreign object blocking the sensor will also cause a malfunction.

Hello, if there is a problem with the sensor or the wiring, there must be a problem with the automatic headlights.

The main reasons are: 1. Sensor damage; 2. The sensitivity of the automatic headlight is related to the characteristics of the light sensor itself, which belongs to the characteristics of the hardware itself, just like the temperature point of the thermostat. It is recommended to contact after-sales for resolution.

Suggested solutions: 1. If the automatic sensing headlight fails, you need to check whether there is a problem with the sensor, or there is a fault in the line connection, it is recommended to go directly to the repair shop to check. Automatic headlights detect the brightness of the sky through a light sensor on the front, and turn on the headlights when they feel that the light is significantly darker.

2. Start the vehicle and energize the whole vehicle; Roll the scroll wheel on the left instrument panel, at this time the sensing distance of the headlights will change, the higher the sensitivity, the farther the distance of the headlights to change light, the lower the sensitivity, the distance to the car is very close to achieve the light. 3. When the light is dimmed while the car is moving, the headlights will automatically turn on and turn off when the light becomes brighter. It is worth mentioning that many people mistakenly think that the "automatic headlights" are designed for crossing the tunnel, but in fact, there is no delay in the opening of the automatic headlights, that is, the headlights will be automatically turned on within ten seconds after the light sensing system senses that the light is dimmed, and according to the traffic regulations, the car must turn on the headlights in advance before entering the tunnel, so the headlights need to be turned on manually in advance when passing through the tunnel.

Automatic headlight failures can be caused by a blown fuse. It is not ruled out that there is a fault in the wiring harness, and it is recommended that the owner go to the 4S store for relevant inspections.

1. If the daytime running lights are turned off in the vehicle settings, as long as the switch of the headlights is turned to the automatic position, it will automatically turn on and off the headlights according to the illumination. There is an auto position on the top of the light button, and this is the automatic mode. It is controlled by a photoreceptor on the right side of the front instrument panel corresponding to the front windshield, which is generally said to have a photoresistor-like feeling.

2. Fuse blowing of daytime running lights: For fuse blowing, generally the left and right sides are not lit, if only one side is not lit, it should not be a problem with the fuse.

3. Wiring harness failure: check the wiring harness between the headlight control module and the daytime running light.

4. Failure of the light guide driver: such as loose or poor connection of the driver plug joint.

5. Daytime running light bulb problem: If there is a problem with the quality of the filament of the bulb, then its resistance will increase with the increase of temperature, which will lead to the decrease of the working current, so that the daytime running light will go out.

There are many good reasons for the failure of automatic headlights, such as unreasonable settings, and it is recommended to restore them and then re-set them. Secondly, if the fuse is blown and it is caused by it, as long as the fuse is replaced in time. Or if there is an abnormality in the light wiring harness, the brigade should thoroughly check and eliminate the cause of the failure.

It may also be that there is an abnormality in the lighting system, which should be checked and repaired in time.

The use of the automatic headlights of the vehicle is very simple, you only need to turn the switch of the automatic headlights to the auto mode, so that it can be automatically turned on and off. When the automatic headlights are turned on, as long as the sensor receives the change of external light, it will automatically turn on or off, so as to improve the safety of driving and avoid unnecessary traffic accidents.

In fact, the automatic headlights of the vehicle can also be disused, just turn off the switch. At night, when the light is not very good, you can choose to manually turn on the headlights of the car, so that there is no problem. However, the automatic headlights are easy to operate, and at the same time, they are also a kind of dismantling orange with a sense of science and technology, which saves a lot of things and can drive with peace of mind.

Summary. Hello dear, I'm glad to answer this question for you, and I have found the answer to this question for you: the reason for the failure of the headlight headlight may be the failure of the headlight bulb, or the circuit of the headlight may be faulty, or it may be that the headlight fuse is burned out Dear You need to go to the auto repair shop for maintenance

Causes of car headlight failure.

Hello dear, I'm glad to answer this question for you, and I have found the answer to this question for you: the reason for the failure of the headlight headlight may be the failure of the headlight bulb, or the circuit of the headlight may be faulty, or it may be that the headlight fuse is burned out Dear You need to go to the auto repair shop for maintenance

After the start of the Suteng, turn on the headlights, the high beam is faulty, the ignition is off, the headlights are turned on, everything is normal, what is the situation.

Hello dear: the headlights play a role in lighting, and they are indispensable equipment when driving at night. If the headlights don't turn on, most of them are caused by problems with the bulbs, and riders can replace them with new bulbs.

If there is a problem with the headlight circuit or fuse, you can repair the circuit or replace the fuse

Kiss should be the fast-rising bulb fault light is caused by a certain bulb of the car is not lit, you need to eliminate the light fault, replace the bad bulb, the bulb fault light will go out without resetting the operation, the bulb fault light is on means that the bulb is broken somewhere in the car, remind the driver to immediately detect the whole car lights, generally after the replacement can be extinguished.

Is it a fuse problem to turn on the headlights after the ignition is turned off?

When the car starts, the other lights are normal, that is, the alarm will be turned on the high beam.

Kiss Kiss may not be, but you may need to get it overhauled.

Could it be that the internal wiring of the headlights is broken?

If there is a problem with the high beam, there may be a problem with the sensor of the high beam.

Dear, there is a possibility, but you still have to go to the garage for a circuit overhaul.

Is a sensor a sensor?

Yes.

Is the sensor a fuse.

Dear Kiss: No.
