Automotive wire colors are represented by the following letters: Black (B), Green (G), Light Green (LG), Blue (L), Light Blue (SB), Violet (VI), White (W), Yellow (Y), Orange (O), Pink (P), Red (R), Gray (GR). Below are specific details about automotive wiring: 1. Specifications: Common wire specifications in automotive wiring harnesses include nominal cross-sectional areas of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, and 6.0 square millimeters, each with its own allowable current load value, suitable for wires used in electrical equipment of different power ratings. 2. Layout: Wiring harnesses should be routed along edges and grooves (designed wiring channels on the vehicle body) to avoid direct pressure on the harness. No exposed wiring harnesses are allowed in the cabin. In visible locations such as the engine compartment, prominent attraction points or conspicuous colors should be set up, and the wiring harnesses installed here should not protrude or be conspicuous.

Does Parking in First Gear for a Long Time Damage the Car?

Yes, it can damage the car. If you park in first gear and the vehicle is suddenly impacted by an external force, the energy from the interaction between the ground and the tires will be transmitted back through the axle, ultimately dragging the engine. This sudden force can easily cause damage to the internal gears of the engine. Additionally, if you forget to press the clutch when starting the car next time, the vehicle may lurch forward, which is not only dangerous but can also harm the transmission gears. Here are some tips regarding parking in gear: 1. Temporary parking: For temporary stops, you can either shift to neutral (N) and engage the handbrake or stay in drive (D) while pressing the brake. 2. Long-term parking: For stops longer than half a minute, such as at a red light, it's best to shift to neutral (N) and engage the handbrake.

What does the exclamation mark in cruise control mean?

There are five possible scenarios when an exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting malfunction. Below is a detailed analysis of these five situations: General malfunction: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic transmission failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake system failure: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal tire pressure: A horizontal line with parentheses below and an exclamation mark in the middle is the tire pressure monitoring warning light. It lights up when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting malfunction: A yellow bulb with an exclamation mark is the lighting malfunction indicator, signaling a problem with the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

Can you pass if the red light stays on without changing?

You can use your mobile phone or dashcam to record the situation, and then proceed after confirming safety. If you receive a ticket, take the collected evidence to appeal, and the penalty will naturally be canceled after verification. The following are situations and handling methods for running a red light: 1. Stop immediately after crossing the line at a red light: If the vehicle has just crossed the stop line at a red light but stops immediately, this will not be penalized. 2. Running a red light under the command of a traffic officer: When there is a conflict between the traffic signal and the traffic officer's gesture, the driver must obey the on-site command of the traffic officer. 3. The entire vehicle crosses the stop line at a red light and stops: If the entire vehicle crosses the stop line and does not continue to move, this is not considered running a red light.

What does the letter P with a circle mean on a car?

The P button in the middle of the car is the electronic parking brake. Here are the relevant details: 1. Working Principle: The electronic parking brake works on the same principle as the mechanical handbrake, both achieving parking control through the friction generated between the brake disc and the brake pads. The only difference is that the control method has changed from the mechanical handbrake lever to an electronic button. 2. Electronic Parking Brake: The electronic parking brake, also known as the Electronic Parking Brake (EPB), integrates the temporary braking function during driving with the long-term parking braking function, and realizes parking braking through electronic control. The electronic parking brake extends from the basic parking function to the automatic parking function AUTO-HOLD. The application of AUTO-HOLD automatic parking technology allows drivers to avoid prolonged braking when the vehicle is stopped. When the automatic electronic parking brake is activated, it can prevent unnecessary sliding of the vehicle.

What Material is Car Wrap Film Made Of?

Car wrap film is made of the following three materials: 1. PVC Material: PVC, also known as polyvinyl chloride, has been extensively researched and tested for use in car color-changing films primarily because its inherent hardness can protect the car body. However, this level of protection gradually weakens over time due to exposure to wind and sunlight, diminishing its quality. Therefore, even if a car uses a color-changing film, maintenance is still necessary. 2. TPU Material: The biggest advantage of TPU is that even when the car is driven in extremely cold or hot regions, the color-changing film still provides excellent protection for the car body while causing minimal damage to the film itself. Most foreign brands use this material to produce color-changing films. 3. Vinyl Material: Vinyl, also known as ethylene, was first invented and used by the American brand SAQETH, a pioneer in the world's top automotive modification and decoration brands. Vinyl is durable, flexible, easy to use, and offers a wide range of colors and surface finishes. Vinyl films can produce color-changing products that look as good as high-quality paint, even surpassing the original quality of premium paint.
