How to continue using ETC after it falls off?

ETC needs to be reactivated after it falls off and is reinstalled. The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and a red light will briefly illuminate. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield. The chip should be inserted into the OBU device. Method to activate the ETC device: Insert and remove the ETC card twice until the electronic tag screen displays "Bluetooth On." If the screen shows "Tag Invalid" when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on the top of the electronic tag to enable Bluetooth directly. Turn on your phone's Bluetooth and open the corresponding mobile app (usually a download QR code is provided on the electronic tag). Navigate to the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt.

What Causes the Exclamation Mark Yellow Light on the Honda Vezel Dashboard?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. Many indicator lights on the car dashboard feature an exclamation mark, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed explanation of the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. Possible causes include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Abnormality: A horizontal line with parentheses and an exclamation mark below represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. In addition, during daily vehicle use, the warning lights displayed on the dashboard are divided into two colors—yellow and red—to indicate different levels of severity: Yellow indicates a fault in the corresponding system that is not very severe. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over immediately and seek professional assistance to prevent unforeseen risks to the vehicle and personal safety. It is important to note that when the car is started, all lights will illuminate as the system performs an automatic self-check. After the check is completed, the lights will turn off. If a light does not illuminate when the ignition is turned on, remains lit without turning off, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly to inspect and resolve the issue to ensure safety.

Will I get points deducted if I stop halfway after accidentally running a red light?

If you stop at the crosswalk and do not continue driving, it is not considered running a red light but rather overstepping the stop line. According to Article 4, Item 5 of the 'Scoring Standards for Road Traffic Safety Violations': Failing to drive or stop as required at an intersection will result in a 2-point deduction. The act of running a red light is clearly defined in the 'Road Traffic Safety Law.' Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and driving through an intersection during a red light constitutes the traffic violation of running a red light. Running a red light refers to the act where the vehicle is within the stop line, the forward direction is already a red light, but the vehicle continues to move forward, with both the front and rear wheels eventually crossing the stop line. This is determined by capturing three photos via electronic cameras: A photo of the vehicle crossing the intersection stop line, including the red light and license plate number. A photo of the vehicle completely crossing the stop line, including the red light and license plate number. A photo showing the vehicle continuing to move, comparing changes in the vehicle's position, including the red light and license plate number. Capturing these three photos confirms the act of running a red light. Running a red light is not considered illegal under the following circumstances: Yielding to special vehicles: Yielding to ambulances, fire trucks, or other special vehicles. If captured by surveillance cameras while yielding to such vehicles, manual review will not record the act of running a red light. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is very low, making it difficult even for electronic police to clearly see the traffic lights. Photos of the violation may be blurred, and accidental running of a red light will not be penalized by traffic police. Emergency situations: If a citizen transports a patient with a critical condition, they can provide proof from the hospital or the person being assisted to the traffic police for verification. If confirmed, the violation record can be cleared. If possible, it is best to call an ambulance to avoid traffic accidents caused by running a red light. Traffic police direction: During peak commuting hours, traffic police may temporarily direct traffic at important intersections. Drivers must follow the gestures of the traffic police.

Why does the engine warning light come on in my newly purchased 2021 Excelle?

There are mainly 7 reasons why the engine warning light comes on in an Excelle: Sensor malfunction: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption occurs, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine warning light. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: Intake turbocharging pipelines and turbochargers can also cause the engine warning light to come on. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the vehicle's intake, it may lead to engine pipeline blockage, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust faults can also trigger the engine warning light. Rear oxygen sensor, three-way catalytic converter, exhaust camshaft, and bearing failures are all causes of exhaust problems, with the three-way catalytic converter being the most common. Using leaded gasoline, lead or silicon-containing lubricant additives, physical damage to the three-way catalytic converter, or fuel system failures can easily cause three-way catalytic converter issues. Anti-theft system malfunction: If the vehicle's electronic anti-theft system malfunctions, or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can also prevent the engine from operating normally and trigger the engine warning light. If the engine warning light comes on, follow these steps: First, check if the engine is running normally and if there are issues such as shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The vehicle will enter self-check mode after powering on. Wait for 5-10 seconds and observe if the warning light on the dashboard turns off. If the warning light remains on, visit a service station as soon as possible to diagnose the issue. The service station can use a portable diagnostic tool to read the fault code, obtain fault information, and perform targeted repairs.

How to Check Coolant Level?

Here are the methods to check coolant level: 1. Check the MIN (minimum) and MAX (maximum) markings on the car radiator. The coolant level should be maintained between MAX and MIN for normal operation. 2. If the coolant level is below MIN, it indicates insufficient coolant and requires immediate replenishment. Below is relevant information about coolant: The primary function of coolant is to cool the engine, with additional anti-rust properties. It mainly consists of compounds like water, ethylene glycol, and propylene glycol, with specified boiling and freezing points. Particularly important is coolant's freezing point, typically around minus forty degrees Celsius.
