Kerry elegant fault

1, EPC is the abbreviation of engine electronic control system, including brake light switch, clutch pedal switch, accelerator pedal position sensor, throttle, engine wiring harness, ECU computer, etc. When the vehicle starts self-inspection after the key is turned on, the EPC indicator light will light up for a few seconds and then go out. If the vehicle does not go out after starting, it means that the mechanical and electronic system of the vehicle has failed. Generally speaking, the common faults of EPC lamp are: throttle body (or parts) and control accelerator pedal: it should be cleaned, maintained and overhauled. Another reason for braking, such as switching sensors (less), is to check the braking-related circuits.

2. The emphasis is on the throttle body. It is important to check the data with ERG (especially diesel vehicles) and position sensor data. These parts also involve the quality of gasoline (diesel)! If it is found that the quality is not good, such as too much water, it is necessary to replace the tubing and clean it thoroughly! Can't be ignored! Another point that is easy to ignore: the temperature sensor. . . . One more thing: matching adaptation. . . .

3. For some models, if this kind of fault occurs during driving, it will sometimes cause serious security risks, which should not be underestimated. It is also partly because of the version problem of ECU, which can be eliminated by upgrading again. In a word, we can't find the reason by analyzing the specific situation. You can go to the after-sales maintenance station for maintenance, and use a special computer to check the data flow, fault code and processing.
