Material: Aluminum alloy, ABS

Fitment:

Replacement for  Accent 1.4L 2010‑2014

Installation Note:
1.Installation and programming is highly recommended by professional engineers
2. When installing the product, pay attention to check the reason for the previous computer board to avoid burning the computer board again with the same fault.
3. Check whether the voltage is normal (voltage about 12V) before installing the computer board, it is recommended not to install it above 15V, check whether the line is normal and whether the iron is good, otherwise there is a possibility of burning the computer board.
4. After installing the computer board (insert the plug for trial operation), the key is turned on to the NO position, and it can be switched back and forth three or four times before starting. 
5. If the car has anti theft function, you need to decode (match) first, this depends on your car and not the computer board

Installation Method:
1. First unload the battery wire a live wire, then install the computer board (circuit board), and then connect the wire,
2. After the car key turn to NO, do not land the car, wait 1-2 minutes, and then ignite,
3. If the fire cannot be caught last time, repeat the previous step and try again, or see if there is dust inside the computer board and the computer board plug, if there is any, you can clean it with a clean brush, or check whether the pins are neat, so that the computer board is basically OK

Workarounds for Common Failures:
1 A fault light indicates a problem with the sensor.
2 Repeatedly burn the computer board "ECU" or can't refuel, please check whether the generator voltage is normal.
3 If there is a lack of cylinder, check whether the spark plug, ignition line, fuel injectionnozzle, etc. are normal.
4 If idle speed is unstable, please check whether the idle motor and throttle valve body are normal and have foreign objects.
5 If it is difficult to start, please check whether the pressure sensor and water temperature sensor are normal.
6 If it cannot be started, please check whether the crankshaft position sensor "Speed Sensor" is normal.

Board Basics:
1 Product installation: confirm that the product model and specifications are normal, install and fix the new circuit board, connect the wiring harness connector, and repeatedly switchthe ignition switch 3-5 times "switch time 2-3 wonderful, close time 4-6 wonderful"
2 Inspection and judgment after installation: whether the idle speed is running normally "heat engine 800-950 rpm, cold engine 1000-1300 rpm", whether the electronic fan is running normally "85.C on, 90.C off", whether the air conditioner is running normally "turn on idle speed increased to 1100-1300 rpm", whether the heat engine exhaust gas is normal "Please check the pressure sensor if it is abnormal", there is idle speed, refueling is weak, please adjust the ignition angle appropriately.djust the ignition angle appropriately.
