What happens when the engine anti theft certification fails?

When the engine starts, there is a sound, that is, after the sound, it will show that the engine anti-theft certification has failed, and it will be displayed after powering on after getting into the car, so check the car battery first.

Power deficits will occur. You can start it by using electricity.

The car key will appear when the battery is low. Get out of the car and press it many times to unlock, lock the car key, there is a time to use, sometimes you can't unlock the lock, the vehicle does not respond, that is, the key is low, change the battery for the key.

If the problem is not solved. Then check the engine start-up insurance and engine anti-theft insurance of the gas car. If you won't look for it, press it one by one to see if it's loose, or wipe it clean to see if it's blackened.

The most common thing about this is that low battery is the most likely problem.

Hello, there may be a problem with the key (such as an illegal key or the key is damaged and cannot be read), there is also a problem with the vehicle computer, and then there is a problem with the wiring. For the sake of driving safety, it is recommended to go to a professional 4S shop for maintenance. Hope mine can help you.

I also had this problem in the car a few days ago, because I was on a business trip, the car was not opened for two months, and the switch of my luggage rack searchlight was directly on the battery, so the car battery was discharged for a long time, and then there was no ignition, engine anti-theft certification failure, electronic steering lock lock lock failure and other problems, and then went to the 4S store to change a battery, the problem was solved.

If he fails to certify, it means that the safety factor of this engine is not enough. If there is a problem with his engine, it is difficult to control it further.

So it's best to get a new engine, at least to ensure that his anti-theft certification is safe, so that he is not easy to be stolen.

Now the engine is in words, he has the engine computer, me.

In the case of inserting the key, your key is matched by the computer to recognize the card, if you answer yes, this is equivalent to giving your vehicle an anti-theft device. Auntie said that in your current situation, you can't hit the top of the train directly if you go to get two positive and negative electrodes. If it is said that the certification fails, or it is the key mismatch, then in this case, we need to use the computer to match the key of the engine accordingly.

Open the door and sit in the main driver's seat in the car, take out the car remote control key, paste it on the one-button start button, hold it for more than 30 seconds, and then.

Continue to stick the one-button start button and press the unlock button on the key fob. You can press the lock button and the trunk button several times or more times.

If you try several times and still can't remove the alarm of engine immobilizer certification failure, you can pull the engine under the dashboard.

The lid handle of the motor compartment, get out of the car and go around the front of the car, face the car logo, squat down, probe to look into the gap of the three chrome strips, and find it.

Conceal the handle, reach in and lift the head cover, there is a horizontal strut lying on the left side of the engine compartment, and lift the struts out of the clip.

The bayonet at the top of the pole is snapped into the recess on the left edge of the headcap and holds the headcap. You go to find the outer 6-angle wrench of M12, and then, the probe finds the positive and negative terminal posts of the battery, pulls open the plastic cover covering the negative electrode with a hand, and then fixes the negative electrode.

Unscrew the clamp nut with an M12 outer 6 angle wrench, loosen the clamp from the binding post, hold it for 1-2 minutes, and then put the clamp sleeve.

Reasons for the failure of engine anti-theft certification: 1. Due to the problem of remote control key and engine computer matching, such as electromagnetic interference nearby, large power supply equipment nearby, and in a very open place; 2. Water enters the front windshield film, and the water will flow along the glass into the center console. Most of the phenomena that occur in the failure of engine anti-theft certification are brake failure, or the steering wheel becomes heavy and laughing, and the ignition does not catch the car, which is due to the engine anti-theft system starting, the car is cut off from oil and power, and there is no fire, and there is no oil pressure, so the brakes and steering power basically stop working.

What is the reason for the failure of engine anti-theft certification? What is the reason for the failure of engine anti-theft certification? Reasons for engine anti-theft certification failure:

1. Due to the problem of matching the remote control key and the engine electric wax pulse, such as electromagnetic interference nearby, large power supply equipment nearby, and in a very open place; 2. Water enters the front windshield film, and the water will flow into the center control along the glass. The phenomenon of engine anti-theft certification failure is mostly brake failure, steering wheel sinking, ignition can not catch the car, this is due to the engine anti-theft system starts, the car is off oil and electricity, can not catch fire, and there is no oil pressure, so the brake and steering power basically stop working. @2019

I laughed a few days ago and the car also had this problem, because I was on a business trip, the car was not opened for two months, and the switch of my luggage rack searchlight was directly on the battery, so the car battery was discarded for a long time, and then there was no ignition, engine anti-theft certification failure, electronic steering lock lock lock failure and other problems, and then went to the 4S store to change a battery Wu Sui, the problem was solved.

The failure of the engine anti-theft authentication is that the car key is not detected, and this situation occurs in part because the car key is out of power or there is a problem with the receiving module:

1. After encountering this situation, riders should check their car keys. The remote control key of the car has a module specially used to start the engine, if the key has electricity but the module is broken, the engine will not start;

2. The most common remote control key is the folding key, which requires a mechanical key to start the engine, and there is a module specially used to start the engine. Without this module, the engine would not have been able to be started even with a mechanical key. The remote control key of the car has a battery inside, and this battery can generally be used for 2 to 3 years.

3. It is very simple to replace the battery for the car's remote control key, you only need to pry open the shell and take out the old battery and replace it with a new one. If your car is equipped with a one-button start system, you can start the engine without inserting a key after getting into the car;

4. Cars equipped with a one-button start system have a special position for induction keys in the car, and the key can be placed on this induction position when the key is out of power, so that the engine can also be started. If the key is out of power, it is recommended that riders replace the battery immediately, so as to avoid Wu Xuan delaying their own car.
