【Car knowledge】Instrument warning lights, strange light! Don't panic, there is way.

Cars have to control the whole vehicle to go to the electronic age had great progress, various states of the vehicle will be displayed in the form of light on the dashboard, and in the assembly has the multi-function screen will have corresponding text message. As long as the understanding of the meaning of these lights display graphics, can know what car out of the situation, how to deal with?

In the light on the dashboard in generally can be divided into three categories:

The first kind of daily light, is the most common turn signals when driving at ordinary times, lighting lamp, seatbelt light, cruise control lights, parking lights, belong to this category, they only have the vehicle prompt action, the working state of each function at ordinary times are very common, so we are familiar, here no longer say more.

The second type has the warning function of light, such as the fuel level indicator, the window cleaning liquid level indicator, this kind of lamp warned owners just add the corresponding oil can be ruled out as soon as possible.

The third kind Also is the main fault indicator lamp, I would like to introduce including engine exhaust system trouble light, trouble light oil system, battery and power generation system trouble light, etc., these fault indicator will seldom at ordinary times on, but as long as the bright has said the vehicle failure or abnormal, then affects the driving safety, small big it could damage the vehicle, need to repair immediately, or contact the vehicle brand 4 s shops.

Airbag trouble light

The fault severity: ★★★
The lamp will not light when driving, if it is found that the indicator lamp lights up when driving or flashing, says airbag or seat belt up binder system has fault, cannot work normally, and the failure due to involve the airbag sensor and circuit is unable to deal with, so need to be done as soon as possible to the 4 s testing and servicing. Safety airbag failure while, but will not affect the vehicle moving, so under the premise of can ensure safety to the car to the 4 s shop repair.

The brake pads wear indicator

The fault severity: ★★★
Modern car brake pads joined the wear sensor, mostly in the brake pads wear to a certain extent will trigger the brake pads wear light, prompted the owner promptly replace the brake pads. Like oil scale, brake pads wear sensor is also left a certain margin, in the fault indicator in a short period of time does not affect the normal operation of braking system, will be allowed to drive to 4 s shop for maintenance and replacement, but also can't think of brake pads and allowance after overhaul time, if excessive wear and then use the brake pads will cause damage to the brake disc, brake caliper piston stroke is too outstanding will also make the piston are difficult place, serious still can cause the entire brake system failure, and replace the brake pads hundreds of block is done, but replace the brake disc and calliper to several thousand dollars! So, in order to train operation safety, brake pad replacement must be done in a timely manner.

The brake system trouble light

The fault severity: ★★★★★
Brake system failure when the light is bright, no matter what circumstances should immediately stop overhaul. The importance of braking system is needless to say, as long as meet the brakes have problems need to be solved at once. Good to find place to park car first, and then check whether the vehicle brake fluid is enough, if it is found that the brake fluid level is too low (less than Min scale), can make a phone call, please rescue workers with some brake fluid to come over, see if I can solve the problem.

But if the brake fluid level is normal, the braking system of mechanical failure, remember that at this time can't continue on the road! Parked on the side of the road, call maintenance service to send someone to repair or rescue vehicle pull car to repair service station for maintenance is the only solution. Note the brake failure, you need to use the hard connection method trailer or use a flat vehicle trailer operations.

Battery and generator trouble light

Painted painted fault severity: ★★★☆
Battery shape of the red light is usually in the key to open the door when the lights up, now is by the battery power supply of the said vehicle, the engine starts, to the generator power supply work, and at the same time for battery charging the battery light is put out. If in the vehicle or if the light glows when engine is running, said vehicle generator defective or there is something wrong with the battery itself. At this point as close as possible to the first car to not have to use electrical appliances, and then to repair service station for maintenance. Because generator system failure at this time, all the cars want to rely on battery power, so the battery consumption is very big, down on the way to the maintenance of vehicles to avoid as far as possible, so as to avoid the battery consumption is too large to be the car again.

ABS (anti-lock brakes system) trouble light

Painted painted fault severity: ★★★☆
ABS indicator light will switch on the ignition switch on for a few seconds, after completion of the self-checking automatically extinguished. If the lights automatically after the car to fill out, or on the road lights up indicates a problem with the ABS system, the vehicle brake can still be performed routinely, but the brake antilock brakes don't work, so I need as soon as possible to repair service station for maintenance. It is important to note the ABS belongs to the braking system components, and according to difference of car types in the ABS system will be integrated EDS (electronic differential lock) and ESP (vehicle stability control system), and other functions, so the ABS trouble light usually joint these system trouble light brake system trouble light even light up.

When the lamp lights up at the same time also don't panic, if the brake trouble light and bright as brake system failure to deal with, if only the ABS light indicates ABS system fault, the braking system can run normally, but the ABS function is no longer work, so can to repair service station for maintenance by oneself, the road should pay attention to keep the low speed, reduce the braking system working frequency and the load.

EPC (engine management system) trouble light

The fault severity: ★★★★
EPC trouble light normally on representative or electronic control engine management system fail, often accompanied by vehicle idle instability or the phenomenon such as engine cold start shaking. But for home owners, especially the public system for owners of EPC fault lights already inured to the weird. Is usually as a result of domestic oil product quality and transport environment caused by environment dirtier, as soon as possible to repair service station for maintenance, in general, cleaning throttle can solve.

Engine exhaust system trouble light

The fault severity: ★★★★☆
The trouble light on the models of different brand name is different, some engine trouble light, some trouble light called exhaust system, but the graphic logo is unity (pictured above); This indicator indicates a problem with the engine exhaust gas monitoring system, commonly known as the ternary catalyst poisoning. If the lights up in the traffic or flashing, please slow down, and drive to the nearest repair service station for maintenance. This fault is mostly caused by the domestic oil product quality of the ternary catalytic oxygen sensor in the system of damage or ternary catalyst poisoning as a result, although able to travel to maintenance service, but also must pay attention to this fault, if oxygen sensor is damaged, change a can solve the problem, and the cost is not much, but if it is damage failure of ternary catalytic converters, is more trouble, but needs several thousand dollars to fix to replace three yuan, so you can not careless, or wallet will hurt!

Trouble light steering system

Painted painted fault severity: ★★★☆
Fault indicator when the vehicle steering system, steering system failure, the steering may be weakened or completely fails, turn the steering wheel of the resistance is several times greater than usual, and the fault also cannot proper motion inspection or maintenance, so the best way is to drive to the nearest service station for maintenance. It's important to note that due to the system failure lose power steering resistance is very big, so the vehicle is not flexible, take extra care in driving, slow down!

The water temperature alarm lamp

The fault severity: ★★★★★
Water temperature alarm said the engine coolant temperature is too high or the coolant fluid level is too low, to immediately stop and shut down the engine at this time, waiting for the engine coolant and then check the coolant level is too low. If the cooling liquid level is too low to add coolant for first aid, if the accessory no spare coolant, also can be replaced with a small amount of pure water. After waiting for the water temperature alarm lamp to eliminate, to continue to drive.

The presence of water temperature alarm that coolant temperature control system of the vehicle out of the question, may be a coolant pipeline leakage, water pump failure, caused by the cooling fan failure, whether that need immediate repair, high operating temperature might damage the engine.

Oil pressure trouble light

The fault severity: ★★★★★
Oil pressure trouble light is one of the serious fault, when encounter the trouble light shining, usually with alarm or multi-function LCD display the tooltip. The need to stop immediately and close the engine! Momentum motivation slightly after cooling
