What is the fault of the EDC light flashing 5

It is an EDC failure, which refers to a problem with the high-voltage electronic injection and electronic control system, which can be understood as a kind of engine failure, which needs to be checked and analyzed with a special computer, and do not loosen the inspection yourself, in case the high-pressure oil pipe injection will cause damage.

Failure, fault, the phenomenon that the equipment "loses the specified function" or endangers safety for some reason during the working process. Failures are sometimes referred to as a type of failure, or they can be lost in the work of the equipment or a failure, but these failures are repairable.

Failure, fault, the phenomenon that the equipment "loses the specified function" or endangers safety for some reason during the working process.

The prescribed function refers to the function that is clearly specified in the technical documentation of the equipment. Failures are sometimes referred to as a type of failure, or they can be lost in the work of the equipment or a failure, but these failures are repairable.

EDC (Electric Diesel Control) appears on the dashboard of the car, which means diesel injection electronic control, which should be an engine failure, and if it can be started, there is no problem; If it can't be started, it is recommended to go to the 4S store for inspection. The engine fault light is on, which is not harmful to the engine, but the fuel consumption increases. Generally, there is a problem with the high-voltage circuit of the engine, the fuel injector, and the oxygen sensor circuit.

First look at the high-voltage wire, spark plug to see if the car is washed, water or falling off in the rain.

Explain that the vehicle's mechanical and electronic systems are malfunctioning.

The reasons for the fault light on: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, power drops, metal squeaks, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and pad. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.

Hello EDC on the dashboard, it should be an engine failure, if you can cover up the liquid tung words that start it's no problem, if you can't make trouble and start it, it is recommended to repair it.

EDC fault light is to indicate that the car's high-voltage electronic injection and electronic control system is faulty, that is, there is a problem with the engine, you need to know to go to the 4S shop to let professional maintenance personnel to test and repair, it is recommended that you do not test and return by yourself to avoid damage to the engine.

EDC letter is the engine circuit failure, usually caused by the maintenance of the starter, because the section loss of the starter has a circuit system, the general maintenance personnel are replaced by the previous starter switch, there is no circuit system, so the computer detects the empty return to the fault, but does not affect the use of the balance.

Automotive EDC is a high-morning pressure electronic injection and electronic control unit fault lamp of the car. When the EDC fault light is on, it indicates that the engine is faulty, if it can be started normally, the problem is not big, it may be that the engine is slippery or the high-voltage circuit or the fuel injector or the oxygen sensor signal is damaged, resulting in more fuel consumption. If it can't start normally, you have to go to the 4S shop to check whether the high-voltage wire, spark plug, etc. are faulty.

Some car owners notice that the EDC light on their car is flashing, and they want to know what the EDC fault light means or whether the EDC fault of the car is serious. This actually indicates that the piezoelectronic devices of the car gushing and the electronic control system have collapsed and failed, that is, the engine has a problem, and it is necessary to go to the car 4S shop to let the maintenance personnel of the technical professional bridge spring to inspect, and the owner does not have to inspect it independently to prevent damage.

When the EDC fault light flashes, it means that the engine is faulty, if it can start and run normally, the problem is not big, it may be that the engine's voltage power supply circuit or fuel injector or oxygen sensor is destroyed, resulting in more fuel consumption. If it can't run normally, you need to go to the car 4S shop to check whether the high-voltage wires and car spark plugs are faulty.

If the owner of the car when the engine can run normally, it means that the damage to the battery and the engine is not large, it is also possible that the car's gasoline and diesel or the air intake is a problem, the owner can check whether the car's electronic throttle valve has more carbon deposits than the sensitive shirt, or the high-pressure oil pump is all normal, or the gasoline filter is not blocked. The best thing is to go to the after-sales repair shop to carry out inspection and maintenance and check the problem.

Millions of car purchase subsidies.
