Can ETC Cards Be Stolen and Swiped?

ETC cards can be stolen and swiped, so it is recommended to remove the ETC card when parking to prevent unauthorized transactions. Precautions for using ETC: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, to prevent issues with the vehicle's ETC device or if it lacks an ETC device altogether, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the vehicle in front. The ETC lane recognition speed is 20 km/h. Driving too fast may prevent the system from reading the vehicle's device information, leading to failed transactions. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will render the electronic tag invalid. In such cases, the device can be taken to the bank where the ETC card was issued or to a highway service center for inspection. If the tag loosens or falls off due to non-human factors, it only needs to be reactivated. When using a debit card linked to ETC, insufficient balance can also cause transaction failures. Follow the guidance of on-site staff to use the manual MTC lane and pay with cash or card. Windshields that are too thick may cause poor signal reception. This is particularly important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.

What are the causes of abnormal engine oil level?

The causes and solutions for abnormal engine oil level are as follows: 1. Oil consumption: Generally, vehicles will consume a certain amount of engine oil during use. Solution: Regularly check the engine oil level and add oil immediately if it is found to be low. 2. Insufficient oil. Solution: If the exhaust pipe emits blue smoke while the engine is running, increase the frequency of inspections and use high-quality oil to prevent excessive engine wear or malfunctions due to insufficient oil. 3. Oil sensor failure: If the oil level is normal but the oil indicator light is still on, it indicates an electrical issue or a faulty oil sensor. Solution: The vehicle should be taken to a repair shop for servicing.

How to Troubleshoot a Clogged Carburetor?

Troubleshooting methods for a clogged carburetor: 1. Main fuel jet, emulsion tube, and main nozzle clogging: The air bleed holes (foam holes) around the main nozzle are blocked (or partially blocked) by dirt, preventing air from entering the main nozzle to form an emulsion mixture, resulting in poor fuel atomization. When the engine is under no load, pressing the throttle makes it difficult to increase the RPM, and the carburetor backfires. While driving, you may experience insufficient power, the engine stalling easily at idle, and difficulty starting. During inspection, if rapidly pressing the accelerator pedal and using the accelerator pump to add fuel to the venturi makes the engine run normally and eliminates stalling, the issue is a clogged main fuel supply system. Disassemble, clean, and unclog it, replacing parts if necessary. 2. Accelerator fuel-air passage clogging: During inspection, rapidly open and close the throttle while observing the accelerator pump nozzle from the carburetor inlet to check if fuel is being sprayed. If no fuel is sprayed, the issue lies with the accelerator pump or a clogged accelerator jet. First, remove the carburetor cover, fill the float chamber with gasoline, and rapidly open and close the throttle to make the accelerator pump piston move back and forth. If the piston encounters significant resistance when moving downward, the accelerator nozzle or fuel passage is clogged. In this case, disassemble, clean the outlet valve, valve seat, and their vent holes, and use compressed air to blow them clear.

How to Solve the Strong Jerking Sensation During Automatic Transmission Deceleration?

Regarding the causes and solutions for the strong jerking sensation during automatic transmission deceleration, the following points are provided: 1. Automatic Transmission Shifting: When an automatic transmission shifts, it is controlled by the computer, which can lead to a jerking sensation if the differential gear change cannot keep up. Solution: Gradually press the accelerator, gently lift the foot, and then press again. Automatic transmission shifting is usually completed at low RPMs. For example, during hard acceleration, the automatic transmission typically shifts between 2500 to 3000 RPM; during gentle acceleration, it usually shifts between 1500 to 2200 RPM. 2. Dirty Throttle: Solution: Clean the throttle.

Can Spark Plugs Affect Engine Power?

Spark plugs do have an impact on engine power. If a spark plug is damaged, it can directly lead to increased fuel consumption and decreased power output in a vehicle. Methods to determine if a spark plug is damaged: Remove the spark plug for observation. Assess its condition based on the following appearance characteristics: A normal spark plug's insulator skirt and electrodes should appear gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a reddish-brown insulator skirt, with electrode gaps between 0.8-0.9mm and no signs of electrode burning. If the spark plug has oil stains or deposits but isn't damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged with signs like blistering at the tip, black streaks, cracks, or melted electrodes, the cause of damage should be identified. After troubleshooting, replace with a new spark plug. Additionally, if the spark plug appears smoke-blackened, it indicates incorrect heat range selection, rich fuel mixture, or oil leakage. Spark plug replacement procedure: Open the hood and remove the engine's plastic cover. Detach the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for external debris like leaves or dust and ensure thorough cleaning. Place the new spark plug into the hole, hand-tighten it for several turns before using the socket wrench. Reinstall the high-voltage wires according to the firing order and reattach the cover.
