What should I do if the data of car power failure is lost?

The treatment method of power failure data loss in Pacific Auto Network: 1, find 4S shop for maintenance, and use professional equipment for maintenance; 2. Reprogram the code, and it will return to normal after driving for a period of time.

There is a lot of information stored in the ECU. You can reset the ECU by disconnecting the power supply. Generally, the computer will be reset about 5- 10 minutes after the car is powered off, and the system time, single mileage, driver's driving habits, vehicle use and other information will be reset to zero. However, for technical parameters such as throttle, it is necessary to give instructions through the external terminal to reset.

Generally, after the battery is cut off, the driving computer will be reset, and some data, such as tire pressure monitoring data and fuel consumption data, need to be reset, and generally return to normal after driving for a period of time. For some data, factory settings may be restored or lost. At this time, you need to go to the 4s shop and use professional instruments to recover.
