Battery incident

7 It has been six years since I have loved my car and has been serving our family diligently and has never left us on the road. There have been some minor problems in the insurance, and all of them can be solved by claim. There has never been a problem with the powertrain. The golden autumn of September has passed, October has arrived, and it will soon turn to autumn. It was also precisely because of the problem of using time that the condition of the vehicle occurred this time;
In fact, the hood of a car is rarely opened, because the number of times when wiper essence is added and water is added to the wiper kettle is very small, and it is usually time to open it for maintenance.
I was going to go on a 200-kilometer self-driving tour, but I also made an appointment. When I was preparing to leave at noon, I found that the vehicle could no longer start. Preliminary estimates are a battery circuit problem.
You can only open the engine compartment and check the battery and fuse box.

Activate. The six-year-old battery came back to life. Adjust the time and find the fault code appearing in the instrument. If you have a dedicated computer, you can delete the code directly. It doesn’t matter if you don’t have a dedicated computer. As long as you run for 1 kilometer, the fault code will be automatically eliminated. The original battery is indeed of good quality, and the old man continues to work. This time we still didn’t leave us on the road. The car was inspired and would always protect us.
