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.
Open the safe box.
Battery and fuse box
Check the safety and there is no problem, and there is no problem with the relay.
On the surface of this picture, my car has been taken care of by mice, and the soundproof cotton has been bitten. The next step is to think about how to prevent mice, which is a headache.
The battery level indicator shows that the level is normal.
Remove the battery first.
To remove a battery, you need to remove the positive electrode first, not the negative electrode. Because if the negative electrode is removed first, as long as the negative electrode is not placed carefully and touches the body, it will become a ground wire, which is prone to danger.
Use the appropriate plum blossom handle.
Remove the positive pole
Remove the battery retaining bolts.
Remove the battery.
The battery liquid level is normal when viewed from the side.
The master tests the battery and has a service life. Can be charged. Then I took the battery back and charged it quickly.
Install the battery according to the reverse method of removing the battery.
After half an hour, the master took back the charged battery.
Tighten the positive and negative pole bolts.
The liquid level is normal.
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.
