Is there 4 faults in the engine control module of Dongfeng Nissan Liwei that need to be replaced?

Single-channel control: three Y lines (1 point 2 wires), cut off 3 red wires in the 2 Y lines, connect 4 sets of ESCs + motors respectively, and then connect the two Y wires to the last Y line without cutting the red line. Finally, the output channel of the receiver is connected.

Doing so allows for centralized control of all outputs. Dual-channel control. Use the V-tail mixer, 2 with the Y line, cut off 3 and red lines in the 2 and Y lines, connect 4 sets of ESCs respectively, connect the 2Y line to the output of the mixer, and connect the mixer input to the receiver 2 channels respectively.

The aim is to be able to control two sets of outputs separately. Four-channel control. This requires a quadcopter flight control board.

The four channels of the flight controller board are connected to the receiver, and the output channels are connected to four ESCs. Achieve hybrid control. The aim is to control the power output of each group or two of them separately.

Why cut 3 red lines? The red line of the ESC is the main line (5V-6V) that the ESC provides power output to the receiver, so that the receiver has power to work normally. However, if each ESC outputs, it will inevitably burn out the ESC (short circuit), so cut off 3 of them and keep one group to power the receiver to work normally.

Be aware of this.

The car engine fault indicator light is on, indicating that the engine is faulty, and the reason for the engine failure is attributed to the oil quality problem, the reason is untenable! It is undoubtedly caused by the quality of the car! The car is still under warranty, and the 4S shop has the responsibility and obligation to replace the bad parts for free, good luck!!

The engine failure light in the car does not mean that there is a problem with the engine, for the current car, this is a very normal phenomenon, I often encounter some cars will have engine failure lights, dismantle the battery, and install it again every few minutes, the fault light may be gone.

Questions and answers. This depends on which fault light it is, if the fault light is lit, red means that it is a serious fault and it is generally not recommended that you continue to drive, if it is yellow, it may be a slight fault, it may be a problem with a sensor, but the vehicle can continue to drive. Generally speaking, if the fault lamp is lit, you need to use the computer to read the fault**, and then repair it according to the fault**.

Ask what the yellow light is all about.

Answer: If the yellow fault light on the left side is the engine fault light, it means that the engine is now faulty, if the engine can still start normally and drive normally, you can drive directly to the repair shop, use the computer to read the fault code, the common reason may be that there is a problem with the oxygen sensor or air flow meter.

Ask what the yellow light is all about.

Go to the repair plant to check the fault with the computer**, and troubleshoot the fault according to the fault**.

It seems that this situation is mainly due to the failure of the electronic control system of the engine, it is recommended that you go to the repair shop to read the fault code with a decoder, and then repair it.

The car engine fault indicator light on, indicating that the engine is indeed faulty, and the cause of the failure is attributed to the quality of the oil is unreasonable, the car is still under warranty, the manufacturer or 4S shop has the responsibility and obligation to replace the bad parts for free! Good luck!

If you are sure that you did not add low-quality gasoline, you ruled it out! There are many reasons for engine failure, and it is not clear at once, the best way is to use the computer to check the fault code, and then repair it in a targeted manner, and then remember to clear the fault code!

First of all, if it is caused by gasoline problems, the 4S shop will not be responsible and is not covered by the warranty. Now the domestic fuel is indeed of low quality, it is recommended that you choose a large gas station for refueling in the future, and try to refuel in the morning.
