The automatic transmission car brake can t be stepped on, and the one button start can t be played,

First, the car is out of gas. Basic common sense, no oil is definitely not on fire.

Second, the battery failure. If the car battery is out of power or malfunctions, it will naturally not be able to ignite.

Third, the spark plug problem. The spark plug is a key component in the automobile ignition system, so whether the spark plug can work normally is related to the working performance and efficiency of the vehicle.

Fourth, too much carbon deposit. Too much carbon in the vehicle will also cause the vehicle to not catch fire, so you need to go to the store regularly to clean up the carbon deposit.

Others, such as oil problems, line failures, etc., will cause the vehicle to fail to ignite, if you need to go to a professional shop for a detailed inspection.

Failure to catch fire is naturally the reason why you can't step on the brakes. As for the reasons why it can't catch fire, the main ones are:

1. Hang the wrong gear. When the automatic transmission car starts, the gear must be placed on the P or N gear, if it is placed on the R or D gear, it will not ignite. There are also some manual transmission cars that will not catch fire if you don't step on the clutch.

2. See if there is oil. I used to go to rescue a car with a friend, but the fuel gauge showed that it was below the red line, so naturally it couldn't catch fire. At the same time, pay attention to the quality of the oil.

When we used to repair the car, we found that there was water and mud in the fuel tank after disassembling it, and with such oil, it was impossible for the car not to break. Therefore, remind the owner to be sure to go to the regular gas station to refuel, and you can bring a gauze wrapped in the muzzle of the refueling gun to filter impurities.

3. No antifreeze is 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.

4. Check whether the battery has electricity. 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 it is generally recommended to replace the battery in time after 2 years. In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failures.

1) Causes of oil supply system: low-pressure oil circuit blockage, loose pipeline oil leakage, high-pressure oil pipe with air, poor technical condition of fuel injector, incorrect fuel injection timing angle.

2) Causes of starting device: power failure, poor contact of electromagnetic switch, poor contact between the commutator of the starting motor and brushes, and slippage of the clutch of the transmission mechanism of the starter.

3) Insufficient cylinder compression pressure: the cylinder gasket is damaged and leaks, the valve is not closed tightly, and the piston cylinder liner is worn and leaking.

4) Insufficient air intake: The air filter element is blocked.

If the car does not catch fire, it means that the engine cannot be turned on, so it causes the brakes.

The pedal can't be pressed. This is a logical relationship between the before and after. Therefore, the car could not hit.

Fire, not because the brake system is faulty.

The solution to the problem that the automatic transmission can't start and the brake can't be stepped on:

1. For models with one-button start, you need to step on the brake when the gear is in P gear.

The car can be started, which ensures that the vehicle will not move when it starts. But there are no on the net.

Few people reported that they had encountered the phenomenon that the brakes could not be stepped on and could not be started, and they suspected that it was.

**There is a breakdown, and some people are worried about whether there will be brake failure when driving.

down the situation;

2. In fact, the reason why the brake cannot be stepped on is likely to be unable to start.

Hit the brakes a few more times after the last time the engine was turned off. Nowadays most of the cars are mined.

The vacuum booster pump is used to assist the brakes, so that we do not need to use the brakes when we apply the brakes.

With a lot of force;

3. Therefore, when the engine is turned off, step on the brakes several times to make the booster pump.

The only vacuum left is gone, so brake the pedal the next time you start.

It will be very hard and you can't step on it;

4. At this time, it is necessary to press the brake pedal with more force, and then press the ignition switch to refer to the blind calendar.

I was able to start the engine. The brakes are noticeably felt after the engine starts.

The pedal is sinking, and this is because the intake pipe of the engine has formed a vacuum, vacuum.

Booster pumps are also starting to help.

Under normal circumstances, no. A vehicle with an automatic transmission cannot be started without applying the brakes.

Strictly speaking, ignition without stepping on the brakes will not cause any damage to the car, but if the gear is not in neutral before the ignition, then the vehicle may rush forward and cause damage when ignition.

Most automatic transmission cars do not need to apply the brakes when they start, unless they are in N gear and the handbrake is not pulled, at this time, for safety reasons, it is necessary to bring some brakes.

Car starting precautions:

1. Turn the key or start button to the ON gear, and let the driving computer self-test each system;

2. After the self-test is completed, confirm that the gear is in P gear or neutral gear, and the handbrake is best pulled up;

3. Step on the brake (the clutch brake of the manual transmission is pressed together), twist the key or press the ignition switch.

My car (2013 BMW 3 Series) used to have to apply the brakes to start, and the doors were not closed to drive. Now my car can be started without applying the brakes, and the door can be driven without closing, what is the fault?

Mine also doesn't hit the brakes, and starts with a press of the button. Is yours settled?

The brake switch is broken, just replace it.

It cannot be started without applying the brakes. Applying the brakes can prevent the car from running forward suddenly, which is a safe design. Automatic transmission cars with one-button start need to press the brake pedal before starting, and make sure that the gear is on the P gear before starting.

Automatic transmission cars have P gear and N gear, both of which can be used when parking, but there are some differences between the two gear key attitudes, and the application scenarios are also different. There is a manuscript locking mechanism in the P file, and there is no respect for the N block.

Precautions for hooking up the n gear.

If you don't pull the handbrake, the car will roll. When the P gear is engaged, the locking mechanism of the P gear locks the gears of the transmission, so that the car will not roll even if the handbrake is not pulled. The P gear is used when the engine is stopped and the ignition is turned off, and the N gear is used when the engine is stopped for a short period of time.

When waiting for the red light, it is recommended that riders do not use P gear but use N gear.

Summary. Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solution Zhaoyuan solutions and solutions! The relevant scheme is as follows: the automatic transmission car can be started without stepping on the brakes, which is generally due to the failure caused by the damage of the brake switch.

Go to the repair shop to check and replace a brake switch. And guess that the approximate cost of replacing the brake switch is about 180 yuan. Different regions, ** will also be different, you can also consult your local car repair shop for details, I hope my can help you!

This may be due to the fact that the owner has applied the brakes several times after parking, causing the vacuum in the brake booster pump to disappear, making it difficult to press the brake pedal without assistance. In addition, the booster pump does not work in the flame-out state, so the owner can try to ignite again, press the brake pedal hard, and then return to normal after starting.

It can also be caused by a leak in the vehicle's brake booster pump or a failure of a component, so the owner will feel very hard because of the loss of the booster pump function when applying the brakes. If the owner of the car does not return to normal after applying the brakes a few times, he should go to a nearby repair shop and wait for the problem to be solved before continuing to drive.

Hello, the car can not start this situation, is divided into two aspects, the first aspect is that the vehicle starts without any response, then this situation.

First of all, you need to check whether this phenomenon is caused by the loss of battery power? If the battery is out of power, you need to charge the battery or replace it with a new one.

In the case of making sure that the battery does not lose power, focus on checking whether there is a problem with the vehicle starter or whether the anti-theft is locked? If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter. 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 rotate, but does not catch fire, so in this case, it is important to check, is the gasoline pump oil pressure insufficient? Or the vehicle engine does not ignite, if the pump oil pressure is insufficient, this situation requires the gasoline pump to be replaced. Check the fuse or wiring of the gasoline pump.

If ignition is not required, focus on checking the crankshaft position, sensor and ignition coil.

If you can't step on the brakes, there may be a brake pump, and I have a problem with the brake fluid.
