If the meter indicator light is not on, first check the power supply fuse of the dashboard.
If the circuit breaker. will need to be replaced. 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 lamp of the dashboard is damaged and needs to be replaced in time;
2. If the power supply line of the dashboard is broken, there will be an open circuit or a short circuit, which will also lead to the car dashboard.
There is no 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 bar to extinguish the indicator light of the timing toothed belt.
3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

If the right one is good, it means that the switch is broken, try whether the double flash is good, if the double flash is bright, then it can be determined that there is a problem with the switch.
-
The fuse or switch is damaged.
-
Flash relay or switch is broken!

If the turn signal does not light up, the turn switch is faultySolution: Use a screwdriver to connect the steering switch live wire and the left and right light wire binding posts respectively. If the resistor 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.
Troubleshooting method: Remove the turn signal cover and check whether the turn signal bulb is damaged. Connect the positive and negative probes of the multimeter to the lead wires of turn signals 1 and 2 respectively, and the gauge hand moves, indicating that the bulb is working well; If the watch hand does not move, the filament has burned out and the bulb should be replaced.
Precautions for the use of turn signals.
1. Turn off the double flash and then turn on the steering (no steering priority function).
Many models do not have a steering priority function, so if you want to turn on the double flash, you should turn off the double flash first and then turn the turn signal switch.
2. It can quickly identify whether the turn signal is faulty.
Turn signals are divided into contact flashers and non-contact flashers. When a contact-based turn signal fails, the corresponding turn indicator on the instrument panel will not flash, while when a contactless turn signal fails, the corresponding instrument indicator will flash more frequently.

Fault symptom: When the ignition switch is turned on and the turn signal switch is turned to the left or right, only one turn signal on one side is not on, or both turn signals on one side are not on, or all turn signals are not on.
Open the hood of the vehicle and connect to the battery of the vehicle with other advantages. Open the door to the cab. Pull the hood switch on the left side of the driver's leg.
Lift the hood. The black letter is the negative pole, which is connected. 5. The red cross is the positive pole and is connected.
The positive and negative poles cannot be misconnected. Charge at the service station after start-up.
Safety hazard: When the battery is exhausted, use the cable to draw power from the battery of another car and do not turn it off for at least 2 hours after getting into the car, let the battery charge automatically. If the battery is more than 5 years old, it is recommended to replace it directly. When the car starts, the engine does not catch fire:
The engine is started by the current of the battery to drive the spark plug to ignite, which may cause the engine to catch fire suddenly, which may be caused by rust or dripping of the battery, and the spark plug of the engine is caused by moisture on rainy days. Check every month or two that the battery fluid in the battery is sufficient. When observing, if the liquid level is between the upper and lower lines, it is considered appropriate.
At the same time, the difference in the level of each tank should also be checked. If the liquid level is insufficient, unscrew the cap on the battery and pour distilled water to make up the liquid level. Then, check the terminals of the battery and use an iron brush to remove the dust that has accumulated on the terminals.
If the clamp is heavily soiled, it can be wiped along the inner wall with sandpaper to remove dirt.

Is there a circuit breaker in the original car insurance, if the insurance bursts, it can be replaced。Check whether the navigation buttons are stuck, including the rset button, which will also cause the computer not to boot.
Secondly, if you have strong hands-on ability, you can remove the navigation, check whether the navigation tail insurance is fused, and if it is fused, replace it. Again, if the screen is still black and does not turn on, use a multimeter to measure whether the B+ and ACC voltages are normal (12V), if the voltage is normal, it is the internal fault of the machine that needs to be opened for maintenance.
Safety Hazards:
If the spark plug is wet, take it out and bake it with a lighter to evaporate the water on it as soon as possible, and the exhaust noise of the car increases, which may be due to the oxidation of the engine exhaust at high temperatures, resulting in leakage of the exhaust system.
If the exhaust system is leaking, please repair or replace the leaking parts at the 4s repair shop in time. Inspect once a year, not only to ensure the normal operation of the exhaust system, but also to reduce the pollution of harmful substances in the exhaust gas to the environment.

Hello, it may be a circuit fault, it is recommended to check the meter circuit!

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.
The car turn signal refers to the flashing indicator in the corresponding direction when the vehicle turns, to warn pedestrians or vehicles in front of or behind the car, and to remind the direction of the car.
Principle 1: The lamp adopts xenon lamp, single-chip microcomputer control circuit, and the left and right rotation strobe works uninterruptedly.
2. Adopt flasher: according to its different structure, it can be divided into three types: wire blocking type, capacitive type and electronic type. Among them, the wire blocking type can be divided into hot wire type (electric heating type) and fin type (bounce type), and the electronic type can be divided into hybrid type (relay and electronic components with contacts) and all-electronic type (no relay).
For example, the bouncing flasher uses the principle of current thermal effect, with thermal expansion and cold contraction as the driving force, so that the spring blade produces a sudden action to turn on and off the contacts and realize the flashing of lights.

Hello, if the right turn signal of the vehicle is not lit, the possible reasons are the fuse is burned out, the right switch of the turn signal switch is damaged, the right side of the line is faulty or the right bulb is burned out, etc.
If the right turn signal is working normally, it means that the fault appears in the turn signal switch, and it can be replaced; If it is not lit up, you need to check the fuse and line on the right side one by one.
-
This kind of fault is mainly to check the relevant circuit of the turn signal, check whether the central control box (estimated to be a BCM setting problem) is faulty, or whether the turn signal line has a short circuit.
Check the anti-theft console. Open the back cover of the main unit, follow the pins of the two brown wires of the plug, and you can see the relay along the circuit board. Carefully cut it with a blade and treat the contacts with sandpaper strips.
Another thing to check the relay, find the alarm host tube with the left flash of the fuse unplugged. Take a look at the fact that the left light does not flash when the alarm is not, other alarms and steering and double flashing are not affected.
Turn signals are important indicators that turn on when a motor vehicle is turning to alert the attention of vehicles and pedestrians in front and behind, left and right. The turn signal tube adopts xenon lamp, single-chip microcomputer control circuit, and the left and right rotation strobe works uninterruptedly. The turn signal uses a flasher to make the light flash.
It can be mainly divided into three types: wire blocking type, capacitive type and electronic type.

Hello, I'm glad to answer for you I'm your car master exclusive technician Concentrate on your intentions and sincerely answer your car questions, and find solutions and methods for you to ask as follows: If the turn signal on one side of the electric car cannot be lit normally, what time do you need to check? First, use a multimeter to measure, turn signal, is there a power supply at the bulb?
If there is a power supply, you can replace the bulb to solve the ** of a bulb is about ten yuan, if the measurement is no power supply, then, you need to check whether there is a problem with the turn signal switch itself, if the switch is a problem, the replacement of the transfer light switch alone can be solved, this switch is generally not higher than 100 or so.
-
If the line is not in good contact, the flash may also be controlled by the computer, so it is also possible that the internal program of the computer is wrong. There is a problem with the flash relay. Check the relay, that is, on a large circuit board, you turn on the steering, see if you can hear the sound, this sound is very regular, the time interval is two seconds to three seconds, if not so, there is a problem with the relay, you can try to replace the relay.
-
When the left and right turn signals and hazard lights are turned on, there is no normal (dripping) and the turn signals are not lit.
This situation is generally divided into two reasons, the flasher relay is damaged, or the turn signal fuse has been blown out, the former can be replaced by itself, and the latter needs to carefully check whether the turn signal circuit has a short circuit, and then replace the turn signal fuse (generally the turn signal fuse has a pattern or text logo in the car safety box). And because the different flasher relays of the vehicle are also different, generally three sockets (see the picture above), so according to the model to buy the matching flasher relay.

Hello. The turn signal is not lit in front and is lit in the back. It is common that the front light is broken or has poor contact or faulty wiring, which can be determined by inspection and then eliminated.
-
If the back bulb is broken, one of the turn signals will not light up, and the frequency of the turn signals will become faster.
-
It should be that there is a problem with the back bulb, and replacing the bulb can solve the problem, and the possibility of line failure is relatively low, and most of them are caused by problems with the bulb.
-
In this case, first check whether the bulb of your rear turn signal has burned out, then check whether the plug of the rear turn signal is loose or falling, and finally check whether the line of the rear turn signal may be broken by something.
-
The turn signal on the rear side does not light up, which is generally caused by the burnout of the bulb of the turn signal, poor contact between the bulb and the lamp base, and problems with the light line.
-
You have to turn on the double flash, if the light is on, it means that the turn signal switch is partially damaged.
If you turn on the double flash, that bulb doesn't light up either. That proves that the light bulb is broken.
-
Explain that the turn signal system is good, only the back bulb or wiring is faulty.
-
Steering switch or wiring [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】
-
The turn signal is not on, the double flashing is the light on, and the turn signal switch is partially damaged;
If the turn signal does not light up, the bulb is damaged, and replacing the bulb can solve the problem;
-
Is the right side lit? Is the indicator light on the instrument cluster on? This has to be investigated step by step.
-
If the right turn signal of the car does not light up, it may be that the bulb is burned and there is an open circuit, which causes the resistance to become smaller and the flashing faster.
If it is not lit throughout, there may be a problem with the steering combination switch, or the fuse is broken.
-
It may be that the bulb inside is broken, this is very ordinary, and it is very simple to change it.
-
Switches, circuit failures or bulb damage will cause the turn signal not to light up, so it is recommended to check and repair it in time to ensure driving safety.
-
You didn't turn on your right turn signal, or your right turn signal bulb was broken.
-
A broken light bulb or a broken control light fuse is the most common, and a broken wiring is less common.
-
Either the contact is bad, or the bulb is broken!
