What is the fault of the circuit instrument display of Yujie electric vehicle that does not go away

Because of the battery capacity.

Drop or battery failure, high current discharge, battery terminal voltage drops sharply, electric vehicle controller.

It's automatically protected, so the car doesn't go. This is the reason why the battery is undercharged or the battery is broken!

Hope mine can help you. Hope!

The reason why the car dashboard lights are fully lit.

The CAN bus is faulty, and the CAN interface of the ECU is not in good contact.

2.Excessive dirt and carbon deposits, abnormal air circulation, and inability to accurately control the normal air intake volume, resulting in unstable gas levels and making the engine not work well.

3.The low fuel pressure combined with the poor constant pressure performance leads to a low level of atomization in the system, making it difficult for the car to start.

Extended Materials. About the car dashboard.

1.The car dashboard is a device that reflects the working conditions of each system of the vehicle. Different cars have different gauges. However, the conventional instruments of general automobiles include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc.

2.A variety of indicators or warning lights are made under the instrument panel of modern automobiles, such as coolant level warning light, fuel level indicator, washer liquid level indicator, charging indicator, high and low beam dimming indicator, transmission gear indicator, brake anti-lock braking system (ABS) indicator, drive force control indicator, airbag (SRS) warning light, etc.

Is it not the key door line is not connected, the controller comes out with a red or yellow thin line that controls the whole car line, instruments, lights are controlled by it,There is a thin red wire on the controller with a fuse box on it, and the fuse inside is burned.

Brand introduction. Yujie is currently the largest investment enterprise in the low-speed electric vehicle industry in China, with a cumulative investment of 100 million yuan. There are three production bases: Qinghe Base No. 1 Factory, Qinghe Base No. 2 Factory and Qihe Base.

The first, second and third plants have a production capacity of 300,000 units and a production capacity of 100,000 engines.

The three bases have built four workshops of stamping, welding, painting and high-quality production technology with car production technology, and have formed a complete system of R&D, manufacturing, sales and after-sales service of electric vehicles and key components.

1. Short circuit of instrument panel wire or connector.

2. Damage to the dashboard.

Second, you can use a multimeter to detect the positive and negative voltage of the instrument to judge the specific fault

1. If normal voltage is detected, the dashboard is damaged and needs to be replaced with a new dashboard.

2. If no voltage is detected, that is, the dashboard wires or connectors are short-circuited, you need to check the cables and connectors, reroute or replace the connectors.

Mine is also this glitch. Just now the after-sales came to repair it, there is a thin red wire on the controller, and there is a fuse box on it, and the fuse inside is burned.

Mine is the same, but what about the car going normally.

And the control line, did you see it? Is there a voltage?

1. The speed control handle, motor, and controller connectors are loose or fall off.

2. The brake lever or foot brake plate is not returned and is in the state of brake power-off.

3. The controller is damaged.

Troubleshooting:

1. Detect or replace connectors.

2. Check whether the brake handle or foot brake pedal is back in place, if damaged, replace it 3. Replace the controller.

5. Turn on the power supply, and the instrument has no displayPossible causes of failure:

1. The power switch is damaged or in poor contact.

2. Poor contact with the battery output socket.

3. The fuse blows.

4. The circuit breaker is not opened.

Troubleshooting:

1. Replace the power switch or fasten the line.

2. Check and tighten the socket line.

3. Replace the fuse.

Yujie four-wheeled electric vehicle, lights, doors, all parts can work, that is, there is a battery on the instrument dashboard that does not display electricity, and the key is also in place, and the car can't go, what an ancient barrier.

Headlight steering wiper instrument light is out of power, sometimes there are times when there is no intermittent is the fault of **? But I can drive.

Yujie electric car suddenly stopped moving forward in driving, the fault sound prompts 1 long and 4 short, the key will start or close and sometimes you can drive!

Yujiema four-wheeled electric vehicle issued a long six short is what is the fault.

The lights are all working, just don't go. The dashboard is out of battery.

First check the power lock, brake power-off, turn it, control,

What is the difference between the distance between the front of the Royal Jet electric car?

Summary. Possible reasons why the LCD instrument of the electric vehicle does not display the power: 1. There is a problem with the instrument 2. There is a problem with the line 3. There is a problem with the motor controller For reference only, it is recommended to find after-sales maintenance to solve it.

Possible reasons why the Hengshan meter of the electric vehicle LCD does not display the amount of electricity: 1. There is a problem with the instrument 2. There is a problem with the line 3. The motor controller has a question about the sail block For reference only, it is recommended to find an after-sales maintenance solution to sell it.

Royal 330 electric car.

Looking for after-sales sales wants you to catch.

There is also a fee. If it doesn't show up, it's a line fault, you can check the line.

There was no problem with the line.

Is the dashboard panel energized.

It's all good during the day, and it shows that it's full after charging at night, and there is also power that doesn't show the power, and you can't go to the car.

Power. That's the battery problem.

How long has the battery been used,

Summary. Hello dear, there are the following concentrated situations: 1. There is a problem with the battery connecting wire, and a certain connecting wire on the battery is loose, or the terminal of a certain battery is corroded and loose.

2. The power supply line of the controller is in poor contact, find the controller of the electric vehicle, mainly check the red and black thick lines of the controller, and see if the two wires are loose and fall off. If it is installed, it cannot be solved, then there is a problem with the motor, and the general motor carbon brush contact is not real, which will also cause the electricity to not go, which needs to go to a special repair shop. 3. For such a situation, you can use the wire to short the positive pole and signal line to short-circuit the handlebar, if the car rotates to prove that the handle is broken, it needs to be repaired or replaced urgently.

In addition, you can turn on the power and twist the knob, and then use the universal meter to measure the positive wire and signal line. 4. If the brake is locked, it will also cause the situation that the power does not go, for this situation, it is easier to deal with it, just release the brake line to solve it. Hope it can help you, dear <>

Dear, do you have any other questions that I need to answer for you? <>

Common faults and solutions of Yujie electric vehicles.

The car has electricity, the display is normal, the car does not go, and there is an alarm sound.

Hello dear, there are the following concentrated situations: 1. There is a problem with the battery connecting wire, and a certain connecting wire on the battery is loose, or the terminal of a certain battery is corroded and loose. 2. The power supply line of the controller is in poor contact, find the controller of the electric vehicle, mainly check the red and black thick lines of the control sail, and see if the two wires are loose and fall off, if there is, then install it.

If it is installed, it cannot be solved, then there is a problem with the motor, and the general motor carbon brush contact is not real, which will also cause the electricity to not go, which needs to go to a special repair shop. 3. For such a situation, you can use the wire short to turn the positive pole and signal line to make the handle short-circuited. In addition, you can turn on the power and twist the knob, and then use the universal meter to measure the positive wire and signal line.

4. If the brake is locked, it will also cause the situation that the power does not go, for this situation, it is easier to deal with it, just release the brake line to solve it. Hope it can help you, dear <>
