What does TCU mean in a car?

The TCU in a car is the transmission control unit, which is only found in vehicles with automatic transmissions. More information about TCU is as follows: 1. The TCU consists of a 16-bit or 32-bit processor, signal processing circuits, power drive modules, etc., and must pass strict electromagnetic compatibility tests. Its operating temperature depends on the installation location, typically inside the cabin, which requires a lower temperature grade, ranging from -40 to 90 degrees. 2. The TCU terminal device can transmit GPS location information, driving speed, vehicle data, and other information wirelessly back to the system platform. Users can monitor and manage the vehicle through computers or mobile phones.

How to Turn on Headlights in an Automatic Transmission Car?

Depending on the vehicle model, there are two ways to turn on the headlights: knob-style and lever-style. Below are the specific introductions to the methods: 1. Knob-style: Located on the control panel to the left of the steering wheel. Turn clockwise once for AUTO, twice for low beam, and three times for high beam. 2. Lever-style: Turn once for parking lights, and twice for headlights. Here are some additional tips: 1. Switching from low beam to high beam: First, turn on the headlights, then push the lever upward and hold for a few seconds to switch to high beam. 2. Switching from high beam to low beam: With the high beam on, push the lever upward and hold for a few seconds to switch back to low beam.

How to Set the Locking Horn for the New Bora?

The locking sound prompt is a feature that is turned off by default in Volkswagen factory settings. To enable it, you need to use a maintenance computer to access the central electrical system and modify the coding of the body control unit. Here is some information about the horn: 1. The horn is the audio signal device of a car. During driving, the driver can emit necessary audio signals as needed and required, to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. 2. Working principle: When the horn button on the steering wheel or other locations is pressed, current from the battery flows through the circuit to the electromagnetic coil of the horn relay. The electromagnetic coil attracts the moving contact switch of the relay to close, allowing current to flow to the horn. The current causes the electromagnet inside the horn to work, thus making the diaphragm vibrate and produce sound.

Under What Circumstances Should a Car Undergo Wheel Alignment?

Introduction to situations requiring wheel alignment for a car: 1. If four new tires are replaced due to severe abnormal wear of the old tires, this will affect the wheel alignment data, necessitating a wheel alignment. 2. The main parameters adjusted during wheel alignment include caster, camber, toe, and kingpin inclination. Adjusting the caster primarily maintains straight-line stability and ensures the steering returns to center; adjusting the kingpin inclination also maintains stability and ensures the steering returns to center; adjusting the camber increases the tire's contact area to counteract adverse effects; adjusting the toe compensates for the adverse effects caused by camber or toe-in. 3. During wheel alignment, the data must be precise. If there are issues with the wheel alignment, the vehicle may experience pulling to one side, affecting balance during turns, acceleration, braking, and suspension load, which can compromise safe driving.

What is the function of the electronic fuel injection system?

The function of the electronic fuel injection system is to precisely control the fuel injection quantity, injection timing, and injection pressure, ensuring that the fuel injected into the combustion chamber achieves optimal performance in terms of power, fuel economy, and emissions. The following are the advantages of the electronic fuel injection system: 1. Improved engine power, fuel economy, and exhaust emission performance. 2. Air-fuel ratio feedback control reduces emissions. Its emission levels are only 50% of those stipulated by European emission regulations, fully complying with Euro I standards. 3. Fuel is directly injected into the intake manifold, ensuring uniform mixture distribution among cylinders. 4. Precise control of ignition timing allows for more complete combustion of the air-fuel mixture, meeting the requirements of various engine loads. 5. Features a self-diagnostic function and a user-friendly interface, facilitating inspection and maintenance by users.
