Daytime running light malfunction may be caused by the following reasons: 1. The fuse of the daytime running light is blown: If the fuse is blown, usually both sides won't light up. If only one side isn't working, it's probably not a fuse issue. 3. Wiring harness failure: Check the wiring harness between the headlight control module and the daytime running light. 4. Halo light driver malfunction: It could be due to loose or poor connection of the driver plug. 5. Daytime running light bulb problem: If there's an issue with the filament quality of the bulb, its resistance will increase as the temperature rises, causing the operating current to decrease and consequently making the daytime running light turn off.

What to Do When the Ignition Switch of a Motorcycle Has Poor Contact?

Motorcycle ignition switch poor contact can be checked by disassembling to inspect the contact condition of the terminals and handling it accordingly. Below are relevant introductions regarding poor contact in motorcycle ignition switches: 1. Explanation: Some new motorcycles have ignition switches with excessive grease applied, which may sometimes affect contact; the motorcycle ignition switch is connected to the live wire, turning on the circuit when the key is turned on and disconnecting it when the key is turned off. 2. Motorcycle usage precautions: (1) Avoid taking your motorcycle to a car wash or letting others wash it unless absolutely necessary. While car washes may seem well-equipped and operate standardly, their pursuit of efficiency often leads to subpar results, potentially causing faults in spark plugs and various circuits. (2) Always allow a hot motorcycle to cool down before washing it. Sudden rinsing of the engine, exhaust pipe, and other components with cold water, as everyone knows the principle of thermal expansion and contraction, can damage the oil seals in various parts, leading to engine oil leakage—a common reason for slight oil leakage in many motorcycles. It can also cause the chrome plating at the connection between the exhaust pipe and the engine to peel off, oxidize, and rust.

What Needs Maintenance and Replacement After Buying a Used Car?

Specific areas that require replacement and maintenance after purchasing a used car: 1. Exterior and Interior: Many people tend to overlook interior cleaning. For the interior, it's advisable to visit a professional cleaning service for a deep clean and disinfection to eliminate any lingering odors and stains. 2. Tires and Brakes: The inspection of the braking system should primarily focus on the thickness of the brake pads. The normal service life of tires is generally 3-4 years or 60,000-80,000 kilometers. You can determine whether they need replacement by checking the production date of the tires and the wear indicators (replacement points) on the tread.

Can the Electric Vehicle Charging Port Still Be Used After Water Intrusion?

Electric vehicle chargers can still be used after water intrusion, but it is essential to ensure the charger is completely dry and free from faults before use. Water in the charger can easily damage the circuit board and control components, and touching it while wet may cause irreversible harm. Water in the charger can lead to electronic component failures. If the charger remains operational, it may overcharge the battery, causing damage. Charging should be based on the battery's capacity, typically taking 8-10 hours to fully charge. Once fully charged, the power should be disconnected promptly. Prolonged connection to the power source may cause overheating of the electronic components inside the charger, potentially leading to short circuits, sparks, and even fire. The charging environment must be well-ventilated, with an optimal ambient temperature of 25°C. Avoid exposing the vehicle to direct sunlight or rain during storage. Additionally, in cold weather, check whether the battery's electrolyte is frozen before charging. Do not charge a frozen battery, as it may explode. Before charging, inspect the electrolyte level—charging should not proceed if the electrolyte is insufficient. The charging area must be well-ventilated, and open flames must be strictly prohibited, as the bubbles in the electrolyte contain hydrogen and oxygen, which can explode upon contact with fire.
