Common faults and solutions for modifying Xenon lamps of various types of vehicles 
1. New Bora: After installation, the light flashes unstable, there is a fault code, etc., and when it is bright, it is not bright, and the blue star with digital technology is also the case.

Reason: Mainly because the popular car computer equipment is very developed, which is very susceptible to current interference and static interference.

Solution: Anti-interference EMI 35W ballast can be solved by direct installation

 

2, Mondeo and Cool, and other vehicles, after installing the xenon lamp, there will be a phenomenon that the electrical equipment is restarted when the light is turned on. If the cool party will have the meter reset to zero, the Mondeo will appear to restart the air conditioner.

Cause: It is caused by excessive current when the ballast is started. Its output current is requisitioned by the headlights, resulting in insufficient total output current.

Solution: Select low-current start ballast, the starting current is not higher than 4.5A when the current is 12V. It is also possible to increase the output fuse of the original car to solve the problem. Generally, a 10A fuse can be added.

 

3, the new Peugeot 307, 407 and 607 and other vehicles, the installation of xenon lights will light the fault code, when the light is on, the light is not bright and the strobe is unstable.

Cause: The above situation is mainly caused by current interference and static interference.

Solution: This problem can be solved by directly installing with anti-interference best EMI ballast

 

4. When the Mingrui car is equipped with two sets of DSP50W ballasts, there will be a small number of cars that will be interchanged with one side and one side will not be lit, and the transition time will become the other side.

Reason: It is because some cars are special, it is a rare part of the car current power supply is not normal, the current can not keep up,

Solution: The solution to this problem is to replace the 50W ballast with a 35W DSP ballast. Normally, the displacement below 1.8L, 35W for the spleen, and 55W for the displacement above 2.0L. solve

 

5, Audi A6L car, some cars installed DSP50W installation, there will be a special phenomenon of airbag alarm

Cause: The input power of the ballast is too high (the input power is about 63W), and the interference caused by the excessive current at startup is caused by the interference.

Solution: Directly install directly with an anti-interference EMI ballast with an input power of 55W.

 

6, the winner car, the ordinary ballast and the blue star will appear after the installation of the lights flashing, the headlights are off, the DSP's 35W installed, the first two days is good, after a few seconds, the headlights are also extinguished

Reason: This situation is a common phenomenon of insufficient power, the computer is turned off directly.

Solution: Install directly with an anti-jamming DSP ballast with an input power of 55W.

 

7. There are some old cars in the winning car. After installing 35W CNC and Hailanxing 50W ballast, after a few seconds of installation, the fault code will be bright.

Reason: It is caused by excessive current alarm at startup, but this car has no computer module to change HID mode.

Solution: It can be solved with a ballast below 4.5A12V, and the anti-jamming DSP35W can be installed directly.

 

8. Jeep and imported American Dodge and other American series cars are all telescopic lights. After installation, the low beam will be disconnected and restarted.

Reason: It is the US car that has the detection and control current device. If the current fluctuation is large or small, the above situation will occur, and the computer will turn off the relevant power supply and restart.

Solution: In the triangular socket of the control line of the telescopic lamp, find the zero-line high-beam plug and add a 100-200 ohm adjustable resistor between them to balance the current fluctuation.

 

9, BMW 3 series of cars, the installation of all xenon lights will appear in the failure code can not be eliminated

Reason: It is the case that the BMW 3 has a low current loop detection. If the bulb does not form a loop, the above situation will occur, and the car key will be looped as soon as it is inserted.

Solution: This problem can be effectively solved by connecting a 4700 microfarad 35V capacitor before the ballast.

Secondly, adding a resistor or a small bulb to form a loop before the ballast can solve this problem.

 

10, part of the BMW 3 series of new cars, with a 35W ballast and capacitors, installed will appear a bright side does not shine, there is a flash of light,

Reason: This is a phenomenon caused by insufficient power. This type of vehicle has computer power limitation in addition to loop detection.

Solution: Switch to an anti-interference 50W ballast and capacitor, or a 35W ballast and connect a 10 ohm resistor.

 

11, the new Volkswagen opened the car, installed 35W and 50W ballast, will be out of the fault code alarm, or a few light to turn off the phenomenon

Reason: Some cars have power control functions. The power of the 35W ballast (the input is generally 43W) is too low, resulting in a general 50W (input power is 63W) and too high.

Solution: Anti-jamming DSP50W ballast is installed directly.

 

12, Rongwei Pinhao and Pinshi and other car-mounted xenon lamps, the CPU interface of the radio will be turned off, and will be normal after reopening

Cause: High voltage interference radiation caused by the ballast during cold start

Solution: Direct installation using an anti-jamming DSP35W ballast with high voltage cable shielded wire.

 

13. Mercedes-Benz C200 has some cars. At the same time, when installing near-far light, there will be 4 lights that only flash and not bright. No matter how to change, there is a problem. This car only installs low beam or high beam without any problem.

Reason: Mainly the total power of the 4 lamps controlled by the car, the range is no problem between 200-240W, 4 exceeds its power, and the general 50W ballast input power exceeds 60W

Solution: All can be solved with anti-jamming DSP55W ballast.

 

14. Some cars, such as Buick LaCrosse and Yuxiang, often have a burning circuit board when installing xenon lamps. The reason is that the current of the headlights passes through the computer board to reach the headlights. Therefore, the required current is extremely low, and the cold start current of the conventional ballast is too large, so the moment of starting will exceed the limit of the computer board and the circuit board will be burned out.

Solution: This type of car is recommended to use an anti-jamming ballast with a cold start below 4.8A. The DSP35W ballast can be installed directly.

 

15. The BMW mini car series and some other cars, after installing the 50W DSP ballast, will flash a few times when the motor is started.

Reason: It is caused by high voltage loop detection when the motor of this part is started.

Solution: Add a 10000 microfarad 35V automotive electrolytic capacitor in front of the ballast to eliminate this situation.

 

16. When some vehicles are equipped with xenon lamps, there will be unstable lighting flashes at startup or after startup.

Reason: This kind of situation is caused by two reasons such as ballast interference and excessive starting current and insufficient power supply.

Solution: Use low current anti-jamming DSP35W ballast

 

17, before the 2009 Volkswagen Sagitar and other vehicles, the installation of two sets of xenon lights will appear when the light is dimly unstable, this situation occurs (35W after 2009 can also be)

Reason: In addition to the HID safety mode factor, there are also reasons for the high power of the ballast and the mutual interference of the ballasts that are too close to each other.

Solution: Change the halogen mode in the computer to HID mode, and put two stabilizers at a certain distance, do not interfere with each other; it is recommended to use a constant power ballast with input power of about 55W.

 

18, some modified cars, such as car owners modified audio and supply, etc., in order to facilitate the modification, the modification shop likes to put the zero line on the ground, the result is that electrical equipment and other equipment will interfere with the car through the good conductor of iron due to static interference Situation of electrical equipment

Solution: Just connect all the neutral wires to the negative pole, and do not let the neutral wires be grounded to prevent interference. It is recommended to use the low-interference DSP35W ballast in the same modified car.

 

19. After the Peugeot 206 is installed and waits for the ballast, the fault code will be issued every 120 kilometers of the car. After the restart, the fault light is not available. The same situation will occur once every 120 kilometers.

Reason: It should be a power problem. The smaller the input power of this car is, the less the fault path is. The DSP35W ballast has a higher effective power and a lower input power, so the mileage is only 90 companies.

Solution: solve the problem by adding a 40 ohm parallel resistor fault eliminator to the white light, or install it with a one-and-a-half telescopic lamp.

 

20, Volkswagen car series, the installation of ordinary ballasts often appear flashing phenomenon after a few flashes

Reason: This is caused by the power supply system of the Volkswagen, which is caused by the power supply to the breakpoint. A break point will occur every time. If the capacitance in the ballast is too small, the above phenomenon will occur.

Solution: Direct installation with anti-jamming DSP ballast can solve

 

21, Suzuki car installed H4 telescopic xenon lamp, installed up fault

Reason: Unknown

Solution: Get it down and reload it once.

 

22, Jinbeige Rui Shi this car, installed water temperature table, oil meter parameters rise, the indicator light is not bright when the light

Cause: Caused by interference

Solution: The BMW decoder with capacitor can be installed directly or directly with the anti-jamming EMI technology stabilizer.

 

23. After the Xenon lamp is installed in the Volkswagen Passat B5 part of the car, the radio will be turned off during cold start and dimming.

Reason: It is caused by high-voltage radiation interference from the ballast.

Solution: It can be solved by ballast with high voltage shielding wire or anti-interference band EMI technology ballast can be directly installed

 

24, Hyundai Yuxiang and Lingxiang two cars, after the modification of the xenon lamp, there will be a phenomenon that the engine will automatically turn off when the light changes during driving.

Reason: It is caused by high voltage radiation interference from ballast

Solution: This problem can be solved with anti-jamming ballast with high voltage shielding wire or anti-jamming with EMI technology ballast can be installed directly

 

25, after 2009, the new Hyundai New Regal, after the modification of the xenon lamp, there will be a situation in which the computer board is burned after using for a period of time:

Reason: It is caused by excessive starting current of the ballast and high-voltage radiation interference, which directly affects the driving module and affects the computer board from the driving module.

Solution: Use the high-voltage shielded line DSP35W ballast to be used or anti-jamming with EMI technology ballast can be directly installed

 

26, BMW, Mercedes-Benz, Audi and other imported cars, when installed 35W will kiss a few times, the installation of ordinary 55W will be unstable current and faulty code phenomenon

Reason: These vehicles have power detection. When the input power is lower than 50W, it will come out. However, the ordinary 55W crying device can not solve the static interference and current interference, and will also cause the vehicle to fail.

Solution: With the anti-jamming 55W ballast, it can solve this problem from the aspects of power and anti-interference.

 

27, Volkswagen Golf, Phaeton, Touran, collar and other vehicles, installed on the ordinary ballast, there are flashes a few down, or start the phenomenon of unstable lighting, and the phenomenon of the fault code

Reason: It is caused by interference. The electronic equipment of Volkswagen is developed and many, and it is required to have a ballast that is not particularly low. Moreover, because there are many electric appliances and there are many places for electricity, the starting current requirement of the ballast cannot be higher than 12V. 4.5A is good

Solution: 35W and 55W with anti-interference DSP can be directly installed to solve this problem

 

28, Volkswagen before the Magotan car before 2009, install the sea blue star stabilizer installed a set of no problem, install two sets will appear flashing lights, install other stabilizers, there will be a fault code, or after a period of time Fault code phenomenon

Reason: The vehicle requires very low interference, and requires a power detection system at startup. Therefore, the starting current of the ballast is also particularly low, preferably lower than 12V4.0A. The current stabilizer has a large interference. The starting current is large or the starting current rises after a period of time exceeds the detection requirements.

Solution: The above problem can be solved perfectly with anti-jamming DSP ballast

 

29, Volkswagen Magotan after the car in 2009, in addition to the above phenomenon, there is also a 35W ballast installed after a few flashes off

Reason: This car has more power detection than before 2009, this phenomenon will occur in ballasts with input power below 50W.

Solution: It can be installed directly with anti-jamming DSP55W ballast
