Purchase notice: Please confirm the problem and fault before purchasing. The products have been professionally tested before delivery. Free trial runs are not provided. If the screws have been fixed, they can only be replaced and not returned.
[About returns]: Please confirm the specific faults of the car before purchasing. The products have been professionally and strictly tested before shipment to ensure that each product is qualified!
If there is a return, within the return period, without affecting the secondary sales, a certain trial fee/depreciation fee will be charged (please consult customer service for specific costs), and the freight will be borne by the buyer! (Note: The board is burned, flooded, and opened without permission. The screws that have been fixed can only be replaced, not returned.).
[About anti-theft matching]: Please confirm whether the car is equipped with anti-theft (key with no chip) before buying. If the car has anti-theft, you need to decode and match when changing the computer version! If the car is not equipped with anti-theft, you can load it directly.
[About installation]: Please find a professional auto repairer to install, and check the line voltage on the car before installation. When installing, plug in the plug and test drive, make sure there is no problem, and then fix the screws. (Note: Before installing a new product, check out the cause of the previous computer board failure, so as not to burn the computer board again with the same failure. Check whether the voltage and wiring are normal and whether the grounding is good during installation. The normal voltage of the computer board is 12V, which is higher than Do not install under normal voltage, otherwise the computer board may be burnt out.)
Installation Precautions:
Pay attention to the product installation, first check the reason for the previous computer board failure, so as to avoid the same failure to burn the computer board again. Check whether the voltage is normal (about 12V). It is recommended not to install above 15V. Check whether the wiring is normal and the grounding is good, otherwise the computer board may be burnt. After installing the computer board, turn the key to the NO position and switch it back and forth three or four times and then start it. (The correct installation method of the computer board: first unplug the battery wire and a live wire, then install the computer board (circuit board), and then connect the wire again, after the car key is turned on the NO, do not leave the car, wait 1-2 minutes , Re-ignite. If it fails to catch fire the first time, repeat the first step and try again, or check whether there is dust in the plugs of the computer board (circuit board) and the computer board (circuit board), if there is any Blow it or clean it with a clean brush, or check whether the pins are neat, so that the computer board is basically OK!)
If the car is equipped with anti-theft, it must be decoded (matched) first. This depends on your car and not the computer board.
If you don’t know how to repair it, please find a repairer who knows how to repair or an experienced car repairer for help. For the burnt-out caused by the car’s natural wiring problem (the burning of the board is caused by faults in the car’s wiring, etc.), our shop Not responsible! Hope buyers can understand!

[Common fault problem solutions]:
1 When the fault light is on, it indicates that there is a problem with the sensor.
2 If you burn the computer board “ECU” repeatedly or can’t add oil, please check whether the generator voltage is normal.
3 If there is a cylinder shortage, check whether the spark plug, ignition wire, fuel injector, etc. are normal.
4 If the idle speed is unstable, please check whether the idle speed motor and throttle valve body are normal and there are foreign objects.
5 If it is difficult to start, please check whether the pressure sensor and water temperature sensor are normal.
6 If it fails to start, please check whether the crankshaft position sensor “speed sensor” is normal.
Basic knowledge of circuit board:
1 Product installation: confirm that the product model and specifications are normal, install the fixed new product, connect the wiring harness connector, and repeatedly turn on and off the ignition switch 3-5 times.
2 Check and judge after installation: whether the idling speed is normal “800-950 rpm for warming, 1000-1300 rpm for cold”, whether the electronic fan is running “85.C on, 90.C off”, whether the air conditioner is operating normally “on idling” Increase to 1100-1300 rpm”, whether the exhaust of the heat engine is normal, “check the pressure sensor if it is abnormal”, the idle speed appears, and the fuel is weak, please adjust the ignition angle appropriately.
