The car can t start, the dashboard doesn t light up, is the key out of power?

It may be a problem with the line, which is generally caused by a short circuit or a bad joint in some places, and needs to be repaired in a repair shop. It may be caused by the battery running out, and it can be solved by charging, for example, taking the battery off and charging it with a charger.

The dashboard does not light up and cannot be started due to the following reasons.

1. The problem of the battery. For example, the battery life reaches the limit, or the battery pile head is loose, the contact is not good, and the pile head may be oxidized.

2. The starting fuse is broken.

3. If all the indicators of the dashboard are not lit and the engine is turned off in time after starting, it is likely that there is a problem with the dashboard, and the common reason is that the instrument CPU is damaged.

You can press the horn first to see if the horn is ringing. If the horn is loud, the battery is fine; If the horn does not sound or the sound is very small, it means that the battery is out of power. In the case, if there is basically no sound at all when the key is running, it is basically certain that the battery has run out of electricity.

Since you can't see the real car, you can't make an accurate judgment on the fault, so it is recommended to immediately contact the 4S store and ask for professional help.

Instrument panel introduction: instrument panel is used to install rigid plates or structural parts of instruments and related devices. According to the type, there are screen instrument panels, frame instrument panels, channel instrument panels, and cabinet instrument panels.

Basically, it's not that the key is dead, it should be that your car's battery is dead.

Hello, there is no electricity in the cab of my car.

You can try to press the horn first, according to the loudness of the horn to judge the power of the battery, if the horn does not sound or the sound is very small, it means that the battery is losing power; In addition, you can also try to run the key, and if there is no sound, you can basically determine that the battery has no power.

The common faults of low-voltage circuits are insufficient battery storage, poor line contact or disorderly knotting, poor battery tie-up, damage to distributors or Hall sensors, damage to ignition switches or poor wiring, and damage to transistor ignition control units or poor wiring.

Common faults in high-voltage circuits are high-voltage wire detachment or leakage, breakdown of distributor cover, ablation and breakdown of distributor distributor head, excessive or small spark plug electrode gap, excessive carbon deposition in spark plugs, damage to spark plug insulator, damage to ignition coil or wiring off.

Check if the fuse is damaged, if it is normal it is a problem with the ignition switch and wiring, light bulb.

Answer: If the indicator light of the remote control is not on or is very dim when pressing the button, then the battery of the remote control may be insufficient; If the remote control indicator is still not on after replacing the battery, you should check whether the positive and negative polarity of the battery is reversed and whether the battery is in good contact with the mount; If there is no problem with the above check, but the remote control indicator is still not on, you should check whether the keys are damaged, if you press some key indicators and some keys do not respond, it is likely that the keys are damaged, or the remote control is damaged.

What happens when you turn on the watch face and it doesn't light up?

When you open the key, the instrument doesn't light up or ignite, and the door doesn't lock. What is the reason.

It has not been used for a long time, the electricity has been used up, and it can't be used for long after charging, and it may be parked for 2-3 days and there is no power, so it is recommended to change.

It may be that the key battery is dead, if there is no power, change the battery, if the key circuit board is not good, then only go to the repair shop to let people repair the most common situation is that the battery is dead, this situation happens suddenly, and even many car owners encounter this situation on the road, causing the car to break down. This may be due to the battery life being up, or the battery may be running out of power (for example, the lights forgot to turn off and were left on overnight).

If the battery is out of power, you need to find someone to pick up the electricity and ignite, and then let the car idle for more than ten minutes to let the battery be charged. Spark plug or ignition coil.

It's broken, this needs to go to the 4S store, that is, the anti-theft light, the anti-theft light is on, which proves that your car key chip has fallen! Or it's broken, or you haven't matched the current key together with the key before, and now you can only find professional and technical personnel to match a chip for you, and the market price is 150-300.

When this phenomenon occurs, 1 can the other key be started, if it can be started, it means that the key that cannot be ignited is faulty (anti-theft chip problem, or not matched well and not locked, etc.); 2. If the two keys can't be played, consider the problem of the vehicle, first, whether the anti-theft control is abnormally disturbed (whether there is a high-voltage line in the surrounding environment.

Banks, hospitals, etc. can use the meter to observe whether there is an abnormal indicator light on or flashing, or use a decoder.

Second, if not, then you need to check whether the engine control system is abnormal.

There are many factors that cause the fault light to turn on, it is recommended to check it with a maintenance decoding device (maintenance computer), and the maintenance computer can read the data stream.

So as to find out or the cause of the failure. Car dashboard.

The engine indicator light flashes and does not catch fire, it is the engine alarm, and the car engine is the engine.

malfunction. The water temperature of the engine cooling system is too high, and the cylinder block is too hot; engine timing; a flow meter that measures the amount of air intake; Throttle.

Failure, similar situation, hurry up to the factory for inspection, it is not recommended to continue to open.

This may be a problem with the engine, because the engine failure is such a regretful situation, you can check whether it is caused by the premature dust engine.

There is a thick lump that may be due to the fact that the connection of the battery is broken and the hidden orange is broken, or it may be because the power of the battery is not particularly sufficient, or it may be because the battery has a power loss.

This may be because the battery of the key is not enough, or other anti-theft systems are under control, in such a situation, you can go to the repair shop for inspection.

Under normal circumstances, when we insert the key in the vehicle and open the key door, the instrument lights will have a process of all lighting, and some of the lights will go out by themselves after a while, and the engine lights will go out after starting, we call this situation the instrument indicator self-test. Under normal circumstances, the vehicle instrument lights need to be self-tested. If you don't self-test, it's faulty.

Today, we take the engine fault light as an example to illustrate that the possible failure reasons for the self-test light not to light are:

After the car opens the key, the engine indicator does not light up and cannot start, mainly because the circuit is not working, specifically:

1. The two contacts between the battery and the starter are loose;

2. The two contacts between the starter and the key door are loose;

3. The two contacts between the key door and the switch are loose;

4. The computer board socket is bent, deformed and loose, and the jack is oxidized and rusty. Disassemble the socket of the computer board to check the jack, and use a steel needle to remove the rust. ECU socket deformation correction:

After heating the socket properly with a hair dryer, quickly insert the ECU, tie it tightly with tape, and release it after cooling to restore the normal shape of the socket.

5. Check the master fuse, ECU fuse, main relay, etc.

Hello 1. Is the battery out of power? Is the battery post virtually connected?

2. Is the engine computer insurance burned? Check the fuse.

3. The key switch is damaged, etc. Screw the key instrument light is not lit, simply put, the engine computer is now out of power (or the dashboard is damaged, the probability is not large) to check the above problems, you may also need to check whether the live wire enters the computer, if the computer is not powered, the oil pump, high-voltage electricity will not have, do not have to find faults, just need to find the reason why the computer is out of power.

Check the power fuse, it may also be caused by a short circuit in the CAN line or a problem with the computer

The solution to the car key dashboard not lighting up and not being able to start the car is: you can try to press the horn firstJudge the power of the battery according to the loudness of the horn, if the horn does not sound or the sound is very small, it means that the battery is losing power; You can also try to run the key, and if you listen carefully, you can basically determine that the battery has no power.

The instrument panel does not light up and cannot be started, and there are problems with the car battery, such as the battery life cycle reaches the limit, the pile head of the battery is loose, the contact is poor and the pile head is oxidized, which are all battery problems, and it is also necessary to check whether the starting fuse is burned out.

Precautions for the use of car keys.

1. Ordinary key: First, the key needs to be released immediately after ignition, if it is screwed for a long time, it will damage the engine strip. The second is to pay attention to the car key and try not to hang it with other keys or accessories.

2. Smart key: First, the smart key uses low-intensity radio waves, so the smart key cannot be put together with electronic devices. The second is not to litter, because the internal circuit of the smart key has weak impact resistance and is easy to be damaged in the event of a violent collision.

Answer: If the indicator light of the remote control is not on or is very dim when pressing the button, then the battery of the remote control may be insufficient; If the remote control indicator is still not on after replacing the battery, you should check whether the positive and negative polarity of the battery is reversed and whether the battery is in good contact with the mount; If there is no problem with the above check, but the remote control indicator is still not on, you should check whether the keys are damaged, if you press some key indicators and some keys do not respond, it is likely that the keys are damaged, or the remote control is damaged.
