Generally, an ETC device can last 2-3 months on a single charge. The ETC user manual does not specify the duration of a single charge. For vehicle owners who do not frequently use ETC, it is recommended to charge the ETC device every 3 months. For wired ETC devices that are not used for a long time, it is advisable to charge them once a month to prevent battery lifespan reduction due to self-discharge. ETC devices are divided into solar panel charging and wired charging. ETC devices with solar panels do not require manual charging, while wired ETC devices need to be charged using a charger. ETC stands for Electronic Toll Collection, which is an electronic toll payment system. To apply for ETC, the following documents are required: the vehicle owner's valid ID card and vehicle registration certificate (original and copies), and if the application is handled by a proxy, the proxy's valid ID card is also needed. The copy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old and own the vehicle in their name. For the current year's vehicle insurance policy, corporate applications require the handler's ID (or driver's license), the company's organization code certificate (or business license), and the company seal. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at toll stations. Backend computer networking technology is used to settle payments with the bank, allowing vehicles to pass through highway or bridge toll stations without stopping to pay fees. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping; Cost-saving: Reduces vehicle wear and fuel consumption by minimizing start-stop cycles, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment systems, ETC technology is more mature and advantageous.

What are the reasons for car shaking after starting?

Car shaking after starting can be caused by: 1. Low ignition energy; 2. Poor fuel atomization at low temperatures; 3. Fuel requiring higher ignition energy; 4. Increased spark plug gap due to prolonged vehicle use; 5. Severe engine carbon buildup; 6. Poor ignition system performance, resulting in inadequate spark plug firing; 7. Unstable oil pressure. Solutions include: 1. If dismantling the intake tract for cleaning is not feasible, use a non-dismantling fuel system cleaning device, though the effect may not be as ideal as dismantling; 2. Consider replacing spark plugs—clean or adjust the gap if possible, but replace if they are in poor condition.

How to Remove the Spare Tire from the Trunk?

The method to remove the spare tire is: Open the trunk and lift the trunk luggage mat to reveal the spare tire. Then, unscrew the knob securing the spare tire to access the tools. The tools for changing the tire are all located in the left-side box, which has two knobs. Unscrew them and lift the cover to remove the spare tire. More details about the spare tire are as follows: 1. A spare tire refers to a backup tire used when the vehicle's tire experiences a puncture or blowout. It can be categorized into full-size spare tires, non-full-size spare tires, and run-flat tires. 2. Full-size spare tire: A full-size spare tire has the exact same specifications as the other four tires on the vehicle, allowing it to replace any temporarily or permanently unusable tire. 3. Non-full-size spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary use. It should only be installed on non-driving wheels, and the maximum speed should not exceed 80 km/h. 4. Run-flat tire: Also known as a safety tire, the industry directly translates it as "tire that can run when flat." Compared to regular tires, run-flat tires do not lose air or lose air very slowly when punctured, maintaining their driving profile. The tire bead remains securely fixed to the rim, ensuring the vehicle can drive for an extended period or temporarily to a repair station. Therefore, vehicles equipped with such tires no longer need to carry a spare tire, effectively hiding the spare in another form across the four tires.

What Causes the Fault Light to Illuminate in a China V Diesel Engine?

Damage to the intake pressure temperature sensor. Temperature sensor damage: Cause analysis: Abnormal intake pressure signal prevents the ECU from receiving correct intake volume information, leading to abnormal fuel injection quantity. This results in incomplete combustion, reduced engine power, and black smoke emission during acceleration. Both wiring harness connection issues and sensor failure can cause this fault. Coolant temperature sensor damage: Cause analysis: When the coolant temperature sensor fails, the ECU detects unreliable output signals and uses substitute values. To protect the engine, the ECU limits engine torque. Engine oil pressure sensor damage: Cause analysis: Severe damage to the engine oil pressure sensor probe leads the ECU to detect no connection with the sensor, and the displayed value on the instrument panel is a substitute value from the ECU.

Why Can't the Rear Door Lock?

First, check if the locking mechanism is functioning. If there's no movement, it's likely due to poor contact in the central control system wiring. If there is movement: Then the issue might be excessive resistance in the locking mechanism, often caused by rust; or it could be that the motor latch position of the door lock has shifted, which can be resolved by adjusting it at a repair shop. Another possible reason is a damaged door lock motor with insufficient pulling force, requiring replacement of the faulty motor. Locking mechanism wiring short circuit: If no sound is heard, it indicates a damaged door lock mechanism or a short circuit (open circuit) in the wiring harness, necessitating replacement of the locking mechanism and inspection of the circuit.
