What is the fault that Dongfeng sign 308 suddenly can t start?

Situation 1: The steering wheel is in a deadbolt state.

At this time, it should be noted that when the steering wheel is not corrected when parking, when it is at a slightly larger angle (such as more than 30 degrees), the steering wheel will be automatically locked, which is also an anti-theft measure, at this time the key may not be screwed, resulting in ignition.

The solution is simple, as long as you hit the steering wheel hard and twist the key at the same time, you can generally unlock the steering wheel lock quickly, and the ignition is an instantaneous thing.

Situation 2: Failure to return gear to P gear when parking.

Think about it, if the D or R gear can be ignited, the jump of the vehicle at the moment of ignition is undoubtedly a huge safety hazard. Therefore, for automatic transmission vehicles (AT, CVT, AMT), the manufacturer will preset this mode, and repeatedly tell in the manual: make sure that the gear is in the P gear position when ignition.

Of course, if you are not in the P gear when parking, the general vehicle will be reminded in the central control instrument display, and some will also be accompanied by a beep reminder, so the probability of this happening is very small. Generally, it is the driver who hurriedly turns off the engine in D gear, and then gets out of the car and leaves. Ignore this issue when you get on the bus again.

Situation 3: One-button start will sometimes encounter the trouble of power loss of the smart key.

Obviously, the key is in the car, but the instrument always shows 'key matching error', this situation is likely to be due to the power loss of the smart key, and the starting system cannot sense the weak radio waves emitted by the key. Therefore, it is recommended to pick up the smart key and put it on the start button, and then press the button to start.

Some models will leave an emergency spare key jack when designing, when the remote control key loses power or because of other convulsions can not be matched correctly, the key is inserted into the hole, and the car can be started by pressing the start button. If it is a borrowed or newly bought car, it should be noted that the brakes need to be applied when igniting the vehicle with a general one-button start. If you press the start button without pressing the brakes, the effect is only to turn on the electrical system in the car.

Situation 4: Check whether the battery has power.

If the ignition is not ignited, it may be due to the loss of power or the expiration of the battery life due to the long-term headlights have not been turned off, and the battery is generally replaced in time according to the maintenance manual.

In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failures. The situation of the vehicle without power is easy to check, just press the horn to know.

Situation five: see if there is oil.

If the fuel gauge shows that it is below the red line, it will not ignite. At the same time, pay attention to the quality of the oil. There have been car owners who found that there was water and mud in the fuel tank after disassembling the car, and with such oil, it is impossible for the car not to break.

Situation 6: No antifreeze added.

Some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, causing the entire waterway to be frozen, the engine to be frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

Hello, when our vehicle fails, these faults will generate a string of **, after the driving computer reads the fault code, it will appear on the dashboard in the form of an indicator. If the engine fault light on the dashboard flashes after you get into the car, it is a reminder that your engine is faulty and you should drive carefully.

After the engine fault light is on, there are three reasons why the vehicle rubber bucket shakes and the power is insufficient, one is that the engine's mixture burns poorly, but when the mixture in the cylinder is too thick, the vehicle will have symptoms such as detonation and shaking. When the mixture is too thin, the vehicle will have a weak acceleration.

If it is not a problem with the mixture, it is a failure in the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug is not in good condition for flashing, which will also lead to the failure of the engine lead gear light and the lack of power for the car to shake.

The third reason is that the fuel supply pressure is abnormal and the intake pressure is caused by the failure of the sensor, if the oil pump supply pressure is abnormal or the intake pressure sensor is wrong and the work is poor, it will cause the body to shake and lack of power.

If your vehicle's fault light is on and your vehicle starts to shake or run out of power, it is advisable to call a tow truck or wait for help for your safety and the safety of others.

The engine fault light is lit and cannot be started, indicating that there is a problem with the engine system.

Peugeot 3008 can't hit the car what is the reason Dongfeng Peugeot 3008 sometimes can't catch fire at a time, you need to play a few socks to bend the locust before the hall can be lit, especially when the car is hot, this situation often occurs, but sometimes normal, the problem is not fixed.

Your bureau believes that the car can not start this situation, is divided into two aspects, the first is that the vehicle starts without any response, then this situation 1: first of all, you need to check whether the battery loss of Tong Jian wheel electric caused by this phenomenon? If the battery is out of power, you need to charge the battery or replace it with a new one.

2: In the case of making sure that the battery does not lose power, focus on checking whether the vehicle starter is a problem or whether the anti-theft is locked, 3: If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter.

4: If there is a problem with the anti-theft system, you need to re-do the anti-theft matching. The second major aspect is that the vehicle engine can turn, but it does not catch fire, so this situation is to focus on checking, 1:

Is it that the fuel pressure of the gasoline pump is insufficient or the engine of the vehicle is not ignition, 2: If the pump oil pressure is insufficient, the gasoline pump needs to be replaced in this case. Check the fuse or wiring of the gasoline pump.

3: If the sail is not ignited, focus on checking the crankshaft position, sensor and ignition coil. The above two aspects are the relevant reasons for the vehicle to not start, as well as the solutions, it is recommended to make a relevant reference!

Summary. When the battery voltage is low, the ABS system will report the code due to the low power, and the instrument will have a brake failure. You can use a charged battery to try it first, or if it doesn't work, you need to use a diagnostic instrument to check the brake signal, network communication and anti-theft system.

ABS pump damage caused by the power network communication is affected, will also cause the inability to start, this situation with the diagnostic instrument will find that the ABS system can not enter, replace the ABS pump on the line, choose to dismantle the pump or the original car pump, replace the new pump need to be reprogrammed with the diagnostic instrument. The dismantling pump can be used directly after installation. The brake fluid should be replaced in time every two years or every 60,000 kilometers to avoid corrosion and damage to the ABS pump due to high water content in the brake oil.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

According to your description. This phenomenon indicates a malfunction in the engine system. It is recommended that you connect a troubleshooter. Do a comprehensive fault diagnosis of the engine system. The failure, the cause has been identified. Hope to adopt, thank you.

Summary. Hello, happy to answer your questions.

Hello, happy to answer your questions.

Dongfeng sign 308 suddenly can't start, you need to check the battery, starter, key, whether there is a fault**, anti-theft, there are more possibilities.

There is a fault code to start and there is no response to the car, the intelligent control box reports the failure of the air and the engine computer can not be recognized, the combination switch under the steering wheel of the fighting family, and the battery monitoring unit is also.

The computer has no communication to check the power supply and grounding.

I measured it, but it still doesn't work, there is a circuit diagram and it is not bothersome to look at the pins of power supply and grounding, and now I find that the blower is not working.

Which year, I'll look to see if there are any.

18 years. I just looked for it, and I didn't find the picture of this ** car.
