What are the reasons why the Xuan Yi one-button start brake cannot be pressed and fails to start?

What causes the Jetta to jerk during cold starts like it's not getting enough fuel?

The reasons why the Jetta jerks during cold starts as if it's not getting enough fuel are: 1. Low engine temperature: Especially during cold starts in winter, the temperature inside the engine is insufficient, and both fuel and lubricating oil are not warm enough. Therefore, more fuel should be injected during cold starts to meet power requirements. Poor fuel atomization at low temperatures leads to reduced ignition energy, which affects performance and causes the car to shake. 2. Carbon deposits in the engine and intake tract: Since carbon deposits can absorb a certain amount of fuel, the ECU makes incorrect judgments. For example, if the computer controls the injection of 100 units of fuel-air mixture, but only 90 units actually enter the cylinder, with 10 units being absorbed by carbon deposits, even if the remaining 90 units of mixture burn completely, the required performance is still not achieved, making shaking inevitable. 3. Ignition system failure: Aging of the ignition system can weaken the ignition energy, causing the ignition coils or spark plugs to fail to ignite continuously or to experience interruptions during ignition. This intermittent ignition prevents smooth and continuous power output, resulting in jerking during acceleration. Therefore, it is important to focus on the maintenance and replacement of the ignition system during daily use. If a spark plug fails while driving, it can easily cause an engine misfire, severely affecting the engine's lifespan.

Why is the ETC unresponsive and the screen not lighting up?

It is possible that the ETC device is out of power or damaged and malfunctioning. Here is some relevant information about ETC: 1. Definition of ETC: The Chinese translation is electronic toll collection, which is an automatic toll collection system for highways or bridges. Through dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and by utilizing computer networking technology for backend settlement processing with banks, vehicles can pass through highway or bridge toll stations without stopping to pay the tolls. 2. Technical Principle: The ETC system uses automatic vehicle identification technology to complete wireless data communication between the vehicle and the toll station, enabling automatic vehicle sensing and identification as well as the exchange of relevant toll data. It employs computer networks to process toll data, achieving a fully automatic electronic toll collection system without the need for stopping or setting up toll booths.

Why is the engine warning light on in the Jiangling Kaiyun?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, triggering the warning light. Fuel/oil quality issues: Failure to use fuel and engine oil as specified by the manufacturer may cause engine wear, leading to the warning light activation. Poor fuel mixture combustion: This can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate. Possible causes include spark plug failure, ignition coil issues, fuel pump malfunction, or clogged fuel lines. Turbocharger problems: Issues with the intake boost system or turbocharger can trigger the warning light. The most common symptom is turbocharger damage, accompanied by oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black exhaust smoke. Intake system issues: Clogged engine air intake passages can trigger the warning light, especially when caused by dirty air filters that haven't been cleaned regularly. Exhaust system problems: Exhaust faults may activate the warning light. Common causes include rear oxygen sensor failure, catalytic converter issues, or exhaust camshaft/bearing faults. Leaded gasoline, improper lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions often cause catalytic converter problems. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or doesn't properly communicate with the engine control unit, it may prevent normal engine operation and trigger the warning light. When the engine warning light illuminates, follow these steps: First check if the engine operates normally. If there's shaking, black smoke, or other abnormalities - especially with a red warning light - do not restart the engine. If the engine starts normally, turn it off for 5-10 minutes. Without pressing the brake pedal, press the start button once or turn the key halfway to the ON position (without depressing the clutch). The vehicle will perform a self-diagnosis for 5-10 seconds. Observe if the warning light turns off. If the light remains on, visit a service center immediately. Technicians can use diagnostic tools to read trouble codes and perform targeted repairs.

Can a Car with a Flooded Dashboard Still Be Driven?

If the water level has exceeded the engine hood or the dashboard panel, then it is called a fully flooded vehicle and cannot be driven. Here is some relevant information about the car dashboard: 1. Introduction to the Car Dashboard: With the advancement of electronic technology and the emergence of new sensors and electronic display components, automotive electronic dashboards have been rapidly adopted. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. 2. Functions of the Car Dashboard: The car dashboard displays the working conditions of various vehicle systems, continuously monitors the car's status, and provides the driver with necessary operational parameter information. It serves as a crucial interface for information exchange between the driver and the vehicle.

Where is the fuel filler switch on the LaCrosse?

The fuel filler switch on the LaCrosse is located on the right side of the trunk for manual operation of the fuel tank cap. Relevant information is as follows: 1. Fuel tank: The Buick LaCrosse 1.5T version has a 55L fuel tank and can use unleaded gasoline with a nominal octane rating of 92 or above. Most vehicles can follow the fuel type and grade indicated on the inside of the fuel tank cap for refueling. If fuel drips onto the car surface during refueling, it should be cleaned immediately to prevent damage to the paint. 2. Dimensions: The Buick LaCrosse has dimensions of 5026/1866/1495mm (length/width/height), standard seating for 5, a top speed of 235km/h, and a 0-100km/h acceleration time of 7.5 seconds. The 2020 LaCrosse is available in four models, featuring a new tail badge naming convention. The latest LaCrosse boasts an elegant and dynamic exterior design.

What needs to be replaced after the pedestrian protection system is triggered?

It is necessary to replace the vehicle's front hood and its accessories, the external airbag system, the sensors of the pedestrian protection system, and the braking system. Here is some relevant information about the pedestrian protection system: 1. Basic version: It can be said that mid-size cars are the easiest among all vehicle types to implement pedestrian protection, as their body dimensions (including the front part) can basically ensure that the head of a pedestrian contacts near the center of the windshield during a collision. This allows for reducing the head injury criterion by modifying the energy absorption design in this area. Therefore, many mid-size cars take full advantage of this feature in their safety design. 2. Upgraded version: By utilizing hood pop-up technology, the engine is instantly raised during a collision, ensuring that the human body does not hit the hard car shell but rather a soft and smooth surface. Upon detecting a pedestrian collision, the vehicle automatically activates the hood pop-up control module, and the built-in ejection device can instantly lift the engine hood, effectively placing an air cushion beneath the falling person.
