In the previous article of instrument identification, the introduction is mainly some of the more traditional and basic instrument identification. I believe that after reading this article, all major users have a new understanding of the instrument logo and gradually become "old birds."

But don't be complacent, because with the increasing number of automotive technology equipment, there are now many new instrument identifications. If we do not follow up the study in a timely manner, the original "old bird" will once again be reduced to a "rookie." Therefore, we must develop a training class and continue to open the instrument to identify those things. Old classmates listen carefully.

In this article, we are still from shallow to deep. We first introduce some relatively shallow gauges and then gradually deepen them. This will allow older students to enter the “state” more easily.

Or start with the introduction of the light logo. After all, the lighting system is used very frequently and it is easy to understand. For the lighting system, if we are familiar with how to use it, we will find some deficiencies. At night when driving and turning, because the light illumination angle cannot be changed synchronously with the vehicle steering, there will be a “blind zone” on the inside of the curve, especially on some mountain roads. If the headlight system can be "synchronized" with the steering, blind spots will be reduced.

Of course, with today's technology, achieving this function is not difficult. In order to improve the safety at night, some A-class and B-class vehicles on the market are equipped with AFS (curve lighting auxiliary system). When the word “AFS” appears on the meter, it indicates that there is a problem with this system.

I believe that many people have the same experience. When people are not concentrated or in a state of fatigue on the expressway, they will inadvertently press the lanes or even deviate from the “madness” of the channel. This situation is very prone to accidents. The yaw system can alert the driver by means of sound, steering wheel shake or light, etc. to reduce this situation. The general yaw system can be turned off and on according to its own needs. If the system is turned on, the above figure will appear on the meter. If your car has this feature, it is advisable to open it at high speeds at night to improve driving safety.

In addition, many car owners have such a bad habit. They may be too busy for themselves and often forget to schedule regular maintenance of their cars. However, many models nowadays are very “intimate”, and when a certain number of kilometers reach the time of maintenance, the meter will show the corresponding prompt to inform the owner. In our long test vehicle 7 above, after reaching a certain number of kilometers, there will be a "serv" logo, to remind owners to maintain. Of course, the prompting mode between different brands is not the same. Some models will remind the owner through the “small wrench” logo. When the car owner sees this kind of logo, he can rest assured that he will not misunderstand that something is wrong with the vehicle and needs repair. When you see a sign that says "small wrench" or "serv", you should go for maintenance. After all, maintenance on time is the best way to maintain good condition.

Today's models not only have a "remind maintenance" of this intimate device, some models also have "fatigue reminder" device. Years ago to go home the New Year, car owners will choose to drive home. In order to reunite with the family as soon as possible, it is natural to drive a car overnight, but it is easy to get tired and be trapped in the night. Some brands have “fatigue reminder” devices. When the system detects driving for more than a certain period of time, the “coffee cup” logo will appear on the meter, along with a sound reminder. Some brands even have models. The power will be disconnected, forcibly preventing the driver from continuing his fatigue driving and prompting the driver to stop and rest. When the above signs, it is best to rest for a period of time and then stop the road, after all, security is still the main.

This is a very intuitive and visual sign. A steering wheel plus an exclamation point sign represents a problem with the helper system. Many people may ignore its existence, because even if the power system has problems, it feels that the steering wheel can still be turned. It is this kind of "lucky" heart that will bring great security risks. Because of problems with the booster system, steering wheel assistance disappears. Although the steering wheel can still rotate, it will become heavy. If an emergency line is needed in a sudden situation, a heavy steering wheel will greatly reduce the evasive ability. So once you see the indicator appear on the meter, you should repair your car as soon as possible.

The above is a relatively simple instrument identification, it is easy to identify, I believe that when the students began to enter the "state", the following describes a more "deep" logo.

This sign “deep” is more difficult to see, because it is generally only seen on the Volkswagen model. If the shift operation is normal, it is difficult to see its “figure”. The logo on the above image appears to be the logo of a shoe. The action is also very similar to pressing a brake. Many people may see this logo will remind us of problems with the brake system. Its appearance is not a problem with the brake system. But when shifting, the brakes were not pressed and the operation was erroneous. If you see this sign, you can rest assured that you can use the car, just pay attention to the shift operation.

In addition to the use of the logo to alert the driver of the use of the engine, the gearbox, which is equally important as the engine, has a corresponding logo to alert the driver. The two meter logos above are unfamiliar to many people, because these two logos are really uncommon, and many models are not equipped with instrument identifications for gearboxes. The reason is that within the service life of the vehicle, as long as it is used normally, the gearbox of the vehicle will not be a big problem. The mark on the left side of the gear plus “exclamation mark” is the fault reminder mark of the gearbox. Generally, when the gearbox fails to shift, the above indicator will appear. With the preceding introduction, it is not difficult to understand the right gear and the “thermometer” logo. This logo is very vivid that the oil temperature of the gearbox at this time is too high. This situation is usually caused by the transmission being overloaded for a long time.

Whether it is the transmission fault light or transmission oil temperature alarm, when we see these two signs appear, we should no longer force the vehicle to drive, because if the transmission gear position is not changed logically during driving, it will cause great Traffic safety hazards. If the gearbox oil temperature is too high, you can let the gearbox oil temperature down before driving, but for gearbox faults, it is safer to use after overhaul.

Now that we have talked about the unique instrumentation of the Volkswagen model, we need to add one. The abbreviation of "EPC" is called the engine electronic power control system. It sounds like a very complicated system. In fact, its "face" is the electronic throttle valve system. Many models on the market today use electronic throttle instead of the original cable throttle to reduce fuel consumption and reduce emissions. It is said that the electronic throttle valve system, but after the "EPC" fault light alarm, not only represents a problem with the throttle part, but also may have problems with the engine control unit, brake switch, clutch switch, etc., will cause "EPC "Call the police. After this phenomenon occurs, in order to find out the real “behind the scenes” reasons, we must also require professional diagnostic equipment. We should not make any judgments on our own.
