I went out on Saturday morning and went home at noon. The car was fine. Go out in the afternoon and plug in the key and turn on the electricity, and the self-test is normal. Start the fire, it’s broken! The whole bad dashboard went black. Thought it was an accidental bad contact of the key switch, it flashed again, and there was no reaction at all. Is the battery running out of power? Open the front cover, use the multimeter to measure the voltage, there is also 12.4V ah, no power loss ah! It’s normal to lock the car by remote control. It should be an old mistake. Three years ago, the key got stuck and couldn’t stop the fire. Later, the lock head was opened to lubricate the lock core and the lock seat, and the problem was solved. / / www.xcar.com.cn/bbs/viewthread.php?tid=27230247
This time there is no response to the forward, or the wear and slip belt does not move and the white head is not powered on. Let’s take a look at the ignition white head first. How to disassemble the steering column decoration board, you can see the “New Suiteng do-it-yourself daily maintenance” post to solve the problem that the key cannot be screwed and the fire cannot be put out.
Turn the keyhole with a screwdriver. It’s smooth. No problem. Open it again to see if there is anything wrong with the contacts.
Except for the dust, there is no obvious problem.
After wiping the white head, the self-test is normal and the ignition failure is the same. I missed a detail at that time. How did the time and time mileage be cleared to zero? Previous experience of lock core failure, and has been equipped with spare parts ready to be replaced. In this way, I think that there is nothing wrong with the white head. It must be that the lock core does not turn to the ignition position. If you notice the zero clearance, you should be able to imagine that the battery may have been disconnected. In this way, there is no homework to change the lock seat, just a battery post.
Determined to change the aluminum seat, who says there is a ready stock?
Remove the steering wheel
Remove hairspring and steering column combination switch
Loosen the 10 hexagonal screw of the plum blossom
It is the No. 5 screw, the hairspring and the combination switch can be removed separately.
The aluminum seat has been exposed.
These are the two anti-theft screws, which are going to be turned out with an electric drill according to the manual method.
Bosch charging drill is at your service.
Punch a hole
Broken screw extractor
I couldn’t eat, I slipped my teeth, and I wasted half a day and failed. We have no choice but to find a way.
The next day, I didn’t buy a small chisel. I bought the punching needle for 2 yuan. As long as the material is hard.
Start from a relatively small angle, avoid the center facing the edge of the round head a few more times, loose will be able to slowly turn out.
Kung fu is spent on these two.
Down steering lock housing and steering column switch base
The original factory is Valeo, and the new one is Changhui made in China.
The quality still seems to be poor, so we should try our best to buy the one from the original factory.
New anti-theft screws
Decorate the fire key to prevent the lock from being pulled out
Restore various plugs
Restore multi-functional steering wheel and airbag
After changing the housing of the steering switch, I feel that there is much less space when turning the key. But the problem is still unsolved. Still can’t start a fire. It was only then that it was found that it might still be a problem with the battery, although the Valta had been used for three years and had not lost power. Or take it home and try to recharge it first.
The static voltage is still 12.23v.
Add a large light bulb load and the voltage drops sharply to 7 volts. This also explains the reason why the instrument clears zero and why the black screen comes from. Using the charger for a long time or virtual voltage, there is really no power storage capacity. Or give up.
Try a Bosch one this time. This is the fourth battery.
So-and-so issued an order for a car, and so on the next day delivery, the third day to the local, did not call the installer did not know this, agreed to come from work and forgot. It was finally loaded on the fourth morning. If the advertisement is good, it is not as good as the service.
Everything’s fine now.
Clear the fault code caused by low voltage power outage. Call it a day.
This time I committed empiricism and decided that the aluminum seat of the switch was broken. Take a detour and treat a small cold as a serious illness. In order to confirm whether the lock core can not turn, take a screwdriver to remove this end in the lock head, twist the lock core and turn it, it will be stuck. Warn you not to move the internal mechanism of the lock core without a lock. Remember!
