How to find the problem when the turning light is not on for car maintenance

Hello. Check whether the fuse is burned and the renewing appliance is burned. If not, it's a line problem. I hope mine is helpful to you! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

All the turn lights don't come on? Partially not lit? One doesn't light up?

All do not light up, control problems, check switch contacts, relays, wiring harnesses.

Part of it doesn't light up, check it for some controllers, and check it for some wiring harnesses.

One doesn't light up, the bulb is broken, the plug is in poor contact, and the branch harness is broken. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello. First of all, please make sure that all of them are not lit, if one of them is not lit, please check whether the bulb is burned out, if not, please check the fuse, flash relay, and switch! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

First of all, check the bulb to see if there is a power supply, then check the fuse, and then check the combination switch Some high-end models of the turn signal are controlled by the computer, if necessary, use the diagnostic computer to read the fault code for maintenance [car problems, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

If you have a problem with the line, you have to have equipment to find a car repairer.

None of them are on, or one is not lit, if one is a bulb, none of them are relays.

Turn on the emergency lights first and see if they will come on. If an emergency doesn't always happen, check the safety and check the relay. If the emergency light is on, check whether the plug of the combination switch is raised, if not, it is the fault of the combination switch.

2.Check the circuit system for short circuits. Check if the distribution center has burn insurance or something.

This phenomenon has never been encountered before. If the car won't start, try turning the key to the ON position, but not to the starting position of the car. Listen to the sound of the oil pump.

If not, the computer is not powered on. Check the circuitry.

3.Turn on the double flash switch and try if the light is on. If so, the problem with the staring is the turn signal switch.

If it doesn't turn on, look at the four turn signals basically don't light up. If the problem is with the bulb, most of them won't break all four bulbs.

Solution to car turn signal not working: the function of car turn signal.

The left turn is downward, and the right turn is up (the most convenient way is to judge the direction of the left hand turn, for example, when turning left, the left hand will definitely turn down on the steering wheel, so that pulling down is smooth enough, and when turning right, the left hand will definitely turn upwards to talk about the auspicious plate, driving ** pull).

To turn on the lights is to turn on the lights, and to turn on the lights is to turn on the side lights of the car, that is, the front and rear lights, and then turn on the low beams.

When the high beam is pressed, the entire lever is pressed. At this time, it is always in the high beam state, and pressing it will not automatically resume.

Another way to turn on the high beam is to lift it up. It doesn't matter if the lights are on or not, just lift the joystick on the internet and it will turn on the high beams. However, when lifted, the joystick automatically recovers.

After a few lifts, the high beams will be on a few times, that is, how many times the high beams will flash when you see the car on the opposite side.

The solution to the car turning and the lights not illuminating: how it works.

1. The lamp adopts xenon lamp, single-chip microcomputer adjustment circuit, and the upper and lower alternating strobe works uninterruptedly.

Second, the use of flasher: according to its different structure, it can include three types: resistance type, capacitive type and electronic type.

Among them, the wire blocking type can include ** type (electric heating type) and fin type (bounce type), and the electronic type can be divided into hybrid type (relay with contacts and electronic components) and fully electronic type (no relay). For example, the bouncing flasher, with the help of the thermal effect principle of electric current, is driven by thermal expansion and contraction, so that the spring plate causes a sudden reaction, so as to open and close the contact and realize the flashing of light.

If the instrument indicator is not lit, first check the power supply fuse of the dashboard, and replace it if it is blown. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The light of the dashboard is damaged, and the light needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there is an open circuit or short circuit, which will also cause the car dashboard to not light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00,000km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round rod to extinguish the timing toothed belt indicator.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

There are many reasons why the turn signal of a car does not light up, and the possible reasons are open circuits, flash relay failures, excessive contact clearance, and other factors.

1. If you want to know the reason why the turn signal is not lit, first check whether the flash relay live wire head has electricity. If there is no electricity, check whether there is a disconnection between the line and the power supply. If there is electricity, use a screwdriver to connect the two reed binding posts of the flash relay, and then the turn signal is on, indicating that the flash relay is faulty and should be replaced in time.

If it doesn't light up, you should check the flash relay calendar.

2. Open the flash relay cover and check whether the coil and resistance are in good condition. If the resistor is hot and the contact cannot be closed, you can press the active contact point; If the turn signal is on at this time, it means that the relay is faulty. Adjustments should be made when the contact gap is too large.

3. If the turn signal does not light up when the active contact is pressed and the contact is closed, the contact can be shorted with a screwdriver, and if the light is on at this time, it means that the contact is oxidized; If the turn signal is not lit, it may be that the turn switch is faulty, and you can use a screwdriver to connect the turn switch live wire and the left and right light wire binding posts respectively. If the light is on, it means that the steering switch is faulty and should be removed for maintenance or replacement.

Note: With this method of exclusion, the car owner can carry out the test himself. If the owner does not understand, he should go to the maintenance center for repair or replacement in time, and try not to delay.

What should I do if my car's turn signal doesn't turn on?

Everyone is familiar with car lights. Car lights often experience some malfunctions. In fact, sometimes, car owners can fix these faults themselves.

First of all, the car owner needs to prepare a basic toolbox. If the left and right turn signal switches are switched, the turn signal will not illuminate. Here's why:

There is a break between the power supply through the flash relay and the live wire of the turn signal switch, or the flash relay or turn signal switch is faulty.

We can check it by following these steps:

First, check if the flash relay's live wire has electricity. If there is no electricity, check if there is a break circuit between this line and the power supply. If there is electricity, connect the two terminals of the flash relay with a screwdriver, and then the turn signal light is on, indicating that the flash relay is faulty and should be replaced.

If not, check the flash relay. Open the flash relay cover and check that the coil and resistor are in good condition. If the resistor is hot and the contact cannot be closed, press the active contact; If the turn signal is turned on at this point, it indicates that the relay is faulty.

If the contact gap is too large, it should be adjusted. If the turn signal is still off when the active contact closure contact is pressed, the contact can be shorted with a screwdriver. If the light is on at this time, the contacts are oxidized.

When the two terminals of the flash relay are shorted with a screwdriver, the turn signal does not light up, which may be the fault of the turn switch. During the inspection, use a screwdriver to connect the live wire of the steering switch and the terminals of the left and right lamp lines. If the light is on, there is something wrong with the steering switch and it should be removed for repair or replacement.

Unlike other car parts, the lights are more complex, and the structure of the car is relatively simple, and the owner can try to repair it himself.

There are many reasons why the turn signal of the car does not light up, and the possible reasons are the broken circuit, the contact gap is too large and other factors

1. Open the flash relay cover and check whether the coil and resistance are in good condition;

2. If the resistance is hot and the contact cannot be closed, the movable contact can be pressed; If the turn signal is on at this time, it means that the relay is faulty. Adjustments should be made when the contact gap is too large.

3. If the turn signal does not light up when the active contact is pressed and the contact is closed, the contact can be shorted with a screwdriver, and if the light is on at this time, it means that the contact is oxidized;

4. If the turn signal is not lit, it may be that the turn switch is faulty, and you can use a screwdriver to connect the steering switch live wire and the left and right light line binding posts respectively. If the light is on, it means that the steering switch is faulty and should be removed for maintenance or replacement.

There are many reasons why the turn signal of a car does not light up, such as open circuit, failure of flash relay, excessive contact clearance, etc.

Check if there is electricity in the live wire of the flash relay.

1.If there is electricity, use a screwdriver to short the two binding posts of the flash relay to insulate it. If the turn signal is on at this time, the flash relay is faulty.

Open the cover of the flash relay and check that the coil and resistor are intact. If the resistor heats up and the contacts cannot close, press the movable contacts. At this time, if the turn signal is on, it means that the flash relay is faulty.

If the contact gap is too large, it should be adjusted appropriately. If the moving contact is pressed, the turn signal remains silent when the contact is closed, and the contact point can be shortened with a screwdriver. If the light is on at this point, the contacts are oxidized.

If there is no electricity, check that the line is open to the power supply.

2.If the turn signal is still off when you short the two binding posts of the flash relay with a screwdriver, it is possible that the turn signal switch is faulty. When checking, you can use a screwdriver to open the live wire and left and right light wires of the steering switch.

If the light is on, the steering switch is faulty and should be removed for repair or replacement.

Extended Information: Common Faults of Turn Signals:

1.When the left and right turn signals and hazard lights are turned on, there is no normal (dripping) and the turn signals are not on. There are generally two reasons for this:

The flasher relay is damaged, or the turn signal fuse is blown. The former can be replaced by itself, and the latter needs to carefully check whether the turn signal circuit is short-circuited, and then replace the fuse of the turn signal (the fuse of the general turn signal has a logo or text mark in the car safety box). Because the flasher relay of different models is also different, it is generally a three-socket, so it is necessary to choose a flasher relay that matches the model.

2.When the left and right turn signals are turned on unilaterally, the frequency of the left and right turn signals is different, one fast and the other slow. This phenomenon is mainly caused by the difference in the power of the left and right turn signal bulbs, or a poor contact somewhere in the turn signal circuit (mostly at the plug).
