Kia Serra FAQ
You can add some fluorine, then dip some detergent with a wet rag, rub out the foam and put it on, and then observe it carefully. Generally, there will be bubbles coming out of the leak.
I suggest you carefully find the leak and fix it, so you can add fluoride, otherwise you will run out of fluoride.
Frequently asked questions ABS fault light is always on. First, the decoder is used to solve the fault code. Generally speaking, the ABS position sensor is faulty, so replace it. ? Poor contact of ABS sensor plug and dirt after driving wheels in rainy days will lead to the induction error of ABS sensor, so try to remove the dirt.
FAQ 3: The battery is always feeding. When ignition is started, ignition will continue. When the engine is started, the battery will discharge with a large current. However, if the battery is discharged with high current for a long time, the battery will be greatly damaged. Do not start for more than 5s at a time. If it is started twice in a row, the interval should be 10- 15s.
The car is not used for a long time, which leads to the automatic discharge of the battery (the central control and anti-theft device of the car still need electricity after the engine is turned off)
The use of external high-power electrical equipment may lead to excessive discharge of the battery (if it is necessary to use it, the engine needs to be started to supply power to the oil generator and battery).
Frequently asked question 4: The air conditioner blower in the car does not work.
1. Check whether the fuse relay is faulty and the circuit is faulty. In particular, check the power cord for loose fan interface, poor contact or wrong wiring.
2. The starting capacitor of the compressor can be disconnected, and use a multimeter to measure whether it is open or disconnected;
3. Whether the compressor coil is burnt out can be confirmed by multimeter.
4. Whether the control circuit board is faulty requires professionals and instruments in the 4S shop to detect.
Frequently asked question 5: directional oil seal leakage
Replace the steering oil seal, remove the oil seal and adjust the rack gap. If there is a professional repairman, it should be repaired.
If it can't be repaired, it is also recommended to replace the original steering gear assembly, not the vice factory.
The leakage of booster oil has little to do with it, but it should be noted that there is an exhaust pipe under the steering gear, and the leaked oil should not drip on the exhaust pipe, which may cause a fire.
Frequently asked question 6: The engine does not start smoothly.
1. When starting, only the starter electromagnetic switch makes abnormal noise, or when starting for the first time, the starter drives the crankshaft to rotate slowly for several times, and then the electromagnetic switch makes abnormal noise, but the crankshaft does not rotate. This phenomenon generally belongs to the battery "broken grid" fault.
2. You can start the temporary stop every time, but you can only turn the crankshaft after stopping for a long time or starting the next day. This phenomenon belongs to the serious self-discharge of the battery, and the aging of its plates and separators is serious, indicating that the battery is close to scrapping.
3. When starting, the starter suddenly weakens, accompanied by the smell of burnt rubber or smoke from the battery, which is mostly caused by poor contact between the pole pile and the pole pile clamp.
4. If the driving gear of the starter collides with the flywheel gear ring of the engine when starting, there are two reasons: first, the meshing cut-in surface of the flywheel gear ring is deformed; Second, the gap between the starter drive gear and the flywheel gear ring is too large. The two can't mesh and the engine can't start.
5. Once the main power switch is turned on, the starter drive gear will mesh with the flywheel gear ring to rotate. First, the holding coil of the starter electromagnetic switch is connected to the wrong power supply terminal; Second, the three wires on the key switch are wrong. The judgment method is: when the key is in the "0" position, the starter drive gear does not rotate, and when it is in the "2" position, the starter drive gear meshes with the flywheel gear ring to rotate together.
6. When the start switch is turned to the start position, the engine cannot be started, and there is no other phenomenon. This kind of fault, first, the key and switch are not connected to the starting circuit because of wear; Second, the starter relay is not connected to the starter electromagnetic switch circuit; Third, the power switch is not connected to the main circuit.
7. There is only a slight "click" sound when starting, and there is no response. It is the sound made by the starting relay. At this time, as long as the tail of the electromagnet is pressed to force the electromagnet to move forward, the starting circuit can be connected to start the engine.
Frequently asked question 7: Carbon deposition on idle valve leads to unstable idle speed, so clean the throttle valve.
Once the idle valve becomes dirty, it will not open. When the idle valve can't be closed when the car starts, the steering wheel of the car will shake, and the car can't start when the traffic jam is serious.
Its main functions are:
1. Controlling the idle speed can keep the idle speed at a given value.
2, according to the change of engine temperature to stabilize the idle speed.
3. Compensation at startup
4. Compensation during deceleration;
5. Compensation when the air conditioner compressor is started! (When the air conditioner is started, the vehicle speed will automatically increase because the idle valve is working) and when it is started, including the high idle speed in the morning. , all related to idle speed.
