WASHINGTON August 29, 2015 Reuters (Epoch Times reporter Yushan comprehensive compilation report) every day, we open to start the car engine, and then driving down the road, it seems that there is no time, or simply did not think to look at the car's engine running how. However, for the majority of cars on the road every time you start the car, it will in fact continue to be checked to ensure that key components on the car, such as engines, electrical systems, emissions and brakes are working properly. These findings can also help you determine whether your car needs maintenance and repair.

 

We can take household electrical fuse panel (switchboard) make an analogy. If a particular circuit household electrical system short-circuit fault, the specific circuit breaker on the distribution panel will start to cut off the circuit in question. In the car, OBD system will not shut down any system or function on the car, just send a warning signal warning lights on the car dashboard to the driver and told the driver of potential problems that may occur. Car repair shop can issue a sensor triggered car computer records, car diagnostics to confirm that the fault position and fault components. All cars since 1996, the Environmental Protection Agency (EPA) regulations in the United States sales must be by having an on-board diagnostic systems, also known as OBD. OBD system is installed in the vehicle set contains many different important parts of the diagnostic system of sensors, these sensors to the diagnostic system check report their area of ​​responsibility is working properly. When one or more sensors find a specific area of ​​the vehicle is not in accordance with the requirements of the design work, the sensor will trigger a specific warning light on the car dashboard light, thereby alerting drivers need to matters require special attention.

In the 1980s, the car has OBD system installed. But the weight of all light vehicles and since 1996 at 8,500 pounds (3,856 kilograms) or less trucks are equipped with second-generation onboard diagnostic system called OBD-II. A new generation of higher engine OBD system will incorporate emission testing standards to ensure that emissions vehicles comply with the relevant laws.

However, testing exhaust emissions but with all OBD-II system features a small part. OBD-II system can detect, control and trigger a large number of warning lights on the car dashboard, and these warning lights are tips related to the future of automotive repair.

 

Type car warning lights

 

Although the 1996 car after all OBD-II systems must be installed before this date a lot of cars produced on its dashboard report warning lights have begun to use the. The warning lights can be used depending on the vehicle while slightly different, but the most commonly seen is the check engine light warning light. Check Engine Light warning lights or engine maintenance also commonly known as a fault indicator or MIL.

The MIL lamp is usually yellow or orange, and can display an image of the engine. When the MIL is on, you may not need immediately to your car to the nearest car repair shop, unless MIL light starts blinking. MIL light flashes to indicate the presence of your engine potentially serious problem that requires immediate repair.

Brake warning light is another common warning light on the dashboard. When any part of the braking system problems need attention, the warning light will illuminate. The warning lights are usually red, and usually displays the word "brake" "brake" word. If the anti-lock braking system (ABS) warning light comes on, it means the ABS system has potential problems, ABS system may shut down on their own until the problem is resolved. Even if the ABS function is turned off, the normal braking function is still valid, but we must take measures as soon as possible, or to the nearest car repair shop for maintenance.

In addition to checking engine and brake warning lights, there are other important warning lights including battery warning light, battery warning lights indicate the battery can not be charged to the normal power or generators to the battery is not charging properly, or possibly both. Oil warning light indicates the engine oil shortage, low oil pressure. Airbag warning light indicates that one or more airbags may not work properly in an accident. Temperature warning light is usually a thermometer symbol is displayed, and indicate the engine is experiencing overheating. Since each car has a different type of warning lights, so check the car instruction manual to identify the most accurate description of each warning lights. ◇
