Automatic transmission not moving with warning light on can be caused by the following reasons: Torque converter: The torque converter shaft is locked, causing the fuel injection pump to stop working. Lubricating oil: The lubricating oil passage is blocked, leading to insufficient lubrication and resulting in planetary carrier burnout. Oil pump shaft: The oil pump shaft is broken, causing the oil pump to stop working or the differential to lack oil and burn out. Transmission: The transmission oil pan is damaged, causing all transmission oil to leak and resulting in vehicle issues. Transmission valve body or solenoid valve is damaged and not functioning. Loose linkage: The linkage or cable between the shift lever and the manual valve rocker arm is loose, keeping the manual valve in neutral or park position.

When to Add Antifreeze?

Antifreeze should be added when its level is below the standard mark. This liquid must also be antifreeze to ensure it does not freeze at low temperatures, as freezing can cause severe engine damage. Generally, antifreeze should remain unfrozen at least at -30 degrees Celsius. The coolant reservoir has MAX and MIN level marks. Add antifreeze when the level is below the MIN mark when the engine is cold. The amount added should be based on the reservoir's marks, ensuring it stays between MAX and MIN. Additionally, after a certain period, typically 3-5 years or 60,000-100,000 kilometers (depending on the vehicle model and manufacturer's requirements), a complete replacement of the antifreeze is necessary. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking. Antifreeze is not only used in winter but is required year-round. The engine and its cooling system are made of metals such as copper, iron, aluminum, steel, and solder. These metals, when in contact with water under high temperatures over time, can corrode and rust. Antifreeze not only avoids causing corrosion to the engine cooling system but also has anti-corrosion and rust-removal functions.

Does the CRH380B have charging ports?

Yes. The CRH380B(L) model is equipped with two power sockets in each row, located under the backrest of seat C (aisle side) and between seats D and F (also under the backrest). If charging is inconvenient at your seat (e.g., seat A), it is recommended to go directly to the dining car upon boarding. The dining car is more comfortable than second-class seats and, most importantly, offers convenient charging with power sockets available at window-side seats. Below is additional information: Introduction: The CRH380B electric multiple unit (or CRH3-380) was developed by China Railway Corporation for operation on newly constructed high-speed intercity railways and passenger-dedicated lines. The Ministry of Railways designated all China Railway High-speed (CRH) trains, which independently developed key technologies, introduced foreign technology, and were jointly designed and produced, as 'Harmony' trains. Interior Layout: The CRH380B train features various seating classes, including first-class, second-class, observation, and VIP seats. Second-class seats are arranged in a 2+3 configuration; first-class seats follow a 2+2 layout. VIP seats are located in the business car (also known as the VIP car) with a 1+2 arrangement, offering premium reclining seats similar to first-class airline cabins. Like the CRH3 trains, the CRH380B also includes compartments at the ends of the train behind the leading cars, known as observation areas, where passengers can view the driver's cab operations through transparent glass walls.

What to do if the 2021 Sylphy shows an idle start-stop malfunction?

Immediately turn off the engine, then disconnect the positive terminal of the battery. After 5 minutes, reconnect it, insert the key and turn it to ON until the dashboard indicator lights up, then remove the key after 30 seconds. Below are specific details about the engine auto start-stop system: 1. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a traffic light) and restarts it when it's time to move again. The STT intelligent fuel-saving system is a set of controls for engine start and stop. 2. It works by equipping a traditional engine with an enhanced motor that has idle start-stop functionality, allowing the engine to completely shut off when idle stop conditions are met. When the vehicle needs to move again, the idle start-stop motor system quickly responds to the driver's command, rapidly restarting the engine for seamless operation, thereby significantly reducing fuel consumption and exhaust emissions. 3. The STT intelligent fuel-saving system controls the engine's start and stop operations. The system uses a computer to determine the vehicle's status, such as when it's stopped at a red light or in traffic. The computer can then automatically stop the engine without affecting the use of in-car devices like the air conditioning or audio system. This technology can save about 5% of fuel under normal driving conditions and up to 15% in congested areas.

What are the brands of motorcycle shock absorbers?

Motorcycle shock absorber brands include Top, Fast, and Fast. The following are specific introductions to the symptoms of shock absorber failure: Abnormal noise: If the shock absorber makes abnormal noises when the vehicle is driving on bumpy roads, it is very likely that the shock absorber is damaged. Oil leakage: Use a flashlight to check the shock absorber through the wheel arch. When oil leakage is found on the outside of the shock absorber, it indicates that the shock absorber is already damaged. Loose chassis: When the vehicle is driving on bumpy roads, if the body posture is excessively bumpy or unstable, it usually indicates a problem with the shock absorber.

Can the Kawasaki H2R be driven on public roads?

Kawasaki H2R cannot be driven on public roads because it is a racing motorcycle. Below are the specific details about the Kawasaki H2R: Model: It is a high-performance model under Kawasaki. Displacement: This motorcycle is equipped with a 998cc inline-four-cylinder, four-stroke supercharged engine. Engine Technology: Turbocharging and supercharging technologies are rarely used on motorcycle engines. Both turbocharging and supercharging are forced induction technologies that can increase the engine's air intake without enlarging the engine's displacement.

What are the differences between the 4WD versions of the Tayron 330 and 380?

The differences between the 4WD versions of the Tayron 330 and 380 lie in their power output and current sales configurations. The specific details are as follows: Power Output Differences: The Tayron 330 is equipped with a low-power 2.0T engine, delivering a maximum horsepower of 186 hp, a maximum power of 137 kW at 5000 rpm, a maximum torque of 320 Nm within the 1600-4000 rpm range, and an official 0-100 km/h acceleration time of 8.9 seconds. In contrast, the Tayron 380 features a high-power version of the 2.0T engine, producing a maximum horsepower of 220 hp, a maximum power of 162 kW within the 4500-6200 rpm range, a maximum torque of 350 Nm within the 1500-4500 rpm range, and a quicker 0-100 km/h acceleration time of just 7.6 seconds. Sales Configuration Differences: Starting from the 2020 model year, Volkswagen has only equipped the Tayron's 4WD system on the 380 high-power version models. The smaller-displacement 330 version models are exclusively available with a 2WD system. For the 2022 model year, the Tayron 330 offers two variants: the Tayron 330TSI 2WD Luxury Smart Connect Plus and the Tayron 330TSI 2WD Luxury Smart Connect. Similarly, the 2022 Tayron 380 also has two variants: the Tayron 380TSI 4WD R-Line Smart Connect and the Tayron 380TSI 4WD Luxury Smart Connect Pro.
