What should I do if the automatic transmission is out of power and can t catch fire

What should I do if the automatic transmission car is out of power and can't catch fire? Automatic transmission cars are not like manual transmission cars, which can be started by pushing the cart, and automatic transmission cars are determined because of the hardware structure of the transmission, otherwise the transmission will be damaged. So you can't start the cart, how to start the automatic transmission car when the battery is out?

We can take the battery to start the start, and this method can also be applied to any vehicle. First of all, we need to prepare two battery lines, the first step, you need to put the two cars together as much as possible, generally speaking, the car batteries are under the front hood, then the actual operation depends on the implementation of the situation, either the two cars side by side, or head to head, for example:

The rescued vehicle is to disconnect all ignition switches, lights and electrical loads, activate the parking brake of both vehicles, and put the automatic transmission car in P gear.

Then find the batteries of the two cars, distinguish the positive and negative poles of the battery, and generally the positive pole will be marked with a red cover and a "" number:

Remove the electrode cap and clamp the positive electrode with the clip of the red battery wire. In the same way, the red wire is clamped first, and then the black wire is clamped, and the 4 electrodes are connected, even if the wire is completed. Once the wire is connected, you can go to the car that loses power and ignite the car.

It seems that it is very simple to take electricity, but in fact, there are quite a few things to pay attention to, otherwise it is easy to have accidents:

1. Check the voltage marked on the two vehicles, which is generally marked on the battery label. If the rescue vehicle is undervoltaged, it may not work, while if the voltage is too high, it may damage the rescued vehicle.

2. It is best for the rescue vehicle to catch fire to provide a more stable voltage and prevent the power from being pulled down.

3. Don't connect the positive and negative poles, remember to connect the positive and negative negatives. Otherwise, the positive and negative connections will become a short circuit.

4. When operating, the hand should be held on the rubber sheet, and the voltage of the battery is generally not enough to cause an electric shock accident, but it is also necessary to take precautions.

5. The positive electrode is clamped vertically with the electrode, not horizontally. The reason is that the vertical clamp can directly clamp the electrode, the electrode is made of lead, which is relatively soft, and the contact surface with the clamp is larger, otherwise it is easy to spark.

6. When removing the wires, they should be unloaded one by one, and not the two electrodes on the same side should be unloaded at the same time. Generally speaking, the unloading wire is the opposite of wiring, and the black wire should be removed first, and then the red wire should be removed.

7. The negative electrode of the rescued vehicle can be placed on the frame or cylinder block, commonly known as grounding. Because the frame and cylinder block themselves are connected to the negative electrode, the effect is the same as directly connecting the negative electrode. Doing so can prevent a short circuit caused by accidental connection and damage to the battery and the vehicle.

In order to avoid the situation that the battery is out of power, then the owner must pay attention to turn off the on-board electrical equipment, including the air conditioner, before getting out of the car. Check your battery regularly, especially if you've been using it for a while, so be aware that it is likely to be scrapped at any time in the future.

Hurry up and see if the car is out of gas, if there is no oil then naturally it will not catch fire, maybe some people will sneer when they see this, although this mistake is relatively low-level, generally speaking, people will not make it, but this world.

If it is not because of the lack of oil, it is necessary to see if the battery is dead, if the electrical appliances are used for a long time, the battery will lose power and cause it to fail to start. This situation is generally more common in older and long-term idleness.

It can be started with a cart, but it cannot be used very often. In addition, a jumper cable can be prepared for borrowing power to charge the battery in an emergency.

In order to avoid the battery not being able to be charged when it is empty, the owner should prepare a jumper cable in the car, which can be bought in the general auto parts store. However, when connecting jumper cables, you must not mistake the order in which the jumper cables are connected. It is necessary to first connect the positive terminal of the dead battery with the positive terminal of the rescue vehicle battery, and then connect the negative terminal of the rescue vehicle battery with the metal part in the engine of the dead car (grounding wire).

Note: Driving an automatic transmission car because the automatic transmission is equipped with a neutral start switch, so that the transmission can only start the engine in P or N gear, so as to avoid making the car start immediately when other gears are misstarted. Therefore, before starting the engine, always make sure that the gear lever is in P or N gear.

For the multi-plate clutch inside the transmission, although the power has been cut off, the passive plate is driven by the wheel to run at high speed, which is easy to cause resonance and skidding, and has adverse consequences. When you really need to coast on a long slope, you can keep the gear lever in D gear to coast, but you can't turn off the engine.

First, let's talk about how the car starts. Due to the presence of a torque converter in automatic transmission models, the gearbox is not rigidly connected to the engine, so it is not possible to start the car by pushing a cart. This situation can only be started with an external power supply.

This external power supply can be a normal vehicle or an emergency starting power supply. The specific steps to start the external power supply are as follows:

1. Connect the positive pole of the battery of the rescued vehicle to the positive pole of the rescue vehicle;

2. Then connect the negative pole of the rescue vehicle to the iron position of the body of the rescued vehicle (metal position such as body screws). Note: Beware of short circuit in contact between the positive and negative electrodes! Must be connected in strict order!

3. After getting into the car, take off the hitching in the order of first positive and then negative.

First of all, for the automatic transmission model, do not start the cart, it is recommended that it is best to carry a portable charger with the car, in case of emergency, you can use a portable charger to charge, after connecting the charger with the positive and negative ends of the battery, set the charging parameters, start charging, and then start the ignition after charging, you can use it normally.

In addition, there are jumper cables in the car, if conditions allow, you can ask for help from passing cars or relatives and friends, and find a normal car to come and help. Connect the positive pole of the battery of the car to be rescued with the positive pole of the battery of the car to be aided with the jumper wire, and then connect the negative pole of the battery of the two cars, and then start the car by igniting the assisted car. It is worth noting that after the car starts, first disconnect the negative connection wire, and then disconnect the positive connection wire.

In general, for automatic transmission models, when there is no power, if you are not equipped with it, it is recommended to call the emergency ** for help, so that professionals can come to the rescue. Of course, the vehicle should be inspected more often to prevent the occurrence of power failure.

Dear! The method of automatic transmission car can not ignite: first of all, some cars can not be ignited, the car mainly checks whether the gear is not hung on the P gear when parking, if it is not hung in the P gear, then the driving computer may not receive the ignition command.

So if it is because the gear is wrong, the owner can switch the gear to the P gear by stepping on the brake and then pressing the unlock button next to the P gear to start the ignition. Secondly, there is another reason that the car battery is over-discharged, which leads to a loss of power and cannot be ignited, which may be because the owner does not turn off the electrical appliances in the car after parking, or makes a large amount of discharge behavior for charging the mobile phone when the car is parked and the ignition is turned off. If the battery is lost, it will not only shorten the service life of the battery, but also lead to the inability to ignite, if it is determined that it is because of the battery problem, then in this case, the owner may be able to do is to find someone to take the electricity, basically the car can start normally.

Not to mention that the automatic transmission is not easy to turn off.

If the engine is turned off, basically your car will not be able to move. Because of the flameout, your gearbox will be out of play and stuck. And then there seems to be that all cars only have two or three brakes when they are turned off.

You should go to the 4S shop immediately to check, this problem is very serious, and it delays time and affects the safety and life of the car.

1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

2. Emergency power supply: This is a new type of power bank like a thing, there are two kinds of lead-acid and polymer lithium battery, which can help the vehicle with a loss of power to start, and can also have lighting, charging mobile phones and multi-functional supplies used with an inflatable pump to inflate the car. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help.

Be sure to charge it in time after use and keep it full of power to deal with emergencies.

3. Positive, first connect the positive: first turn off all the electrical equipment on the car, make the key in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp firmly the positive pole of the battery of the electric car, and the clamp at the other end to clamp the positive pole of the battery of the rescue vehicle. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

4. Negative connection, negative connection: After the red positive electrode is connected, take out another wire, first clamp the negative pole of the tram battery, the negative electrode is generally black "—" number, and then pinch the other end of the clip, from beginning to end the clip do not touch other places, to clamp the negative pole of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the whole vehicle is basically a negative electrode (that is, commonly known as "tie iron"), if the negative electrode is connected first, when connecting the positive electrode, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle will first ignite and charge the battery, and then the no tram enters the vehicle to open the key, at this time the instrument light will be lit smoothly, and then try to ignite (not more than 5 seconds), if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then the tram is ignited again, if the starter is no problem, the car has oil in the case of general can be started smoothly, after the non-electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

There may be several reasons why the car cannot ignite, and the steering wheel is in a locked state: when the steering wheel is not corrected when parking, it is easy to have the steering wheel locked, resulting in the key being inserted and not being able to screw, and the car can not be lit. 2

The battery of the car has a power loss: the battery of the car is also a consumable, and it is recommended to replace the battery once in 2-3 years. If the battery is out of power and cannot ignite, you can take the method of taking electricity, first of all, the front of the two cars "face to face" (the two cars can be as close to each other as possible), and then turn off the rescue vehicle, so as not to burn the battery line due to excessive current, the electrical switches of the rescue vehicle are turned off, open the engine compartment of both sides (some car batteries are placed in the rear trunk, such as BMW), and find the positive and negative poles of the batteries on both sides (with red "+" for the positive pole and black "-" for the negative pole).

Remember the positive and negative poles of the vehicle, don't make the wrong connection.

Next, how to correctly connect the wiring method is: first connect the positive end of the battery of the loss-stricken vehicle with the positive end of the rescue vehicle battery; Then connect the negative pole of the rescue vehicle battery to the wire and then connect it with the iron sheet of the body of the vehicle with power loss (try not to connect the negative electrode, it is easy to produce sparks, and it will cause damage to the battery in serious cases.

Black is the negative wire, and red is the positive wire.

After making sure that the wires are connected correctly and that the contact is good, start the rescue vehicle; Let it run for a few minutes before charging the vehicle with a loss of power. Then start the loss-free vehicle.

If the loss of power vehicle can not start, this is to give the throttle of the rescue vehicle to some oil, and then to start the loss of power vehicle, remember not to force the start, pay attention to the start of the interval, if it can not start, it is necessary to consider whether the wire is too thin, the current caused is not enough.

Remember the positive and negative pole markings on the battery.

When the vehicle is started, the battery clamp can be removed at this time, and the order of taking power should be:

1. First remove the negative pole of the rescued vehicle with the iron wire, and then remove the negative pole wire of the rescue vehicle;

2. Furthermore, remove the positive wire of the rescue vehicle, and then remove the positive wire of the rescued vehicle.

Remember the order of unplugging 4 4

If the motor fails, or the fuel filter surface is clogged and the car doesn't start, it's time to ask a professional to solve it.
