What Causes Several Warning Lights to Illuminate in a Sagitar?

Reasons for several warning lights illuminating in a Sagitar: 1. ECU CAN Bus Malfunction: Poor contact in the ECU CAN interface. 2. Excessive Dirt and Carbon Buildup: Abnormal air circulation prevents accurate control of normal air intake, leading to unstable gas content and poor engine performance. 3. Low Fuel Pressure and Poor Constant Pressure Performance Resulting in Low System Atomization Level: Causes difficulty in starting the car. Below are the types of indicator lights on the dashboard: (1) First Category: Daily indicator lights, such as turn signal lights, lighting indicator lights, seatbelt indicator lights, cruise control indicator lights, and parking indicator lights, belong to this category. They only serve to indicate the working status of various vehicle functions. (2) Second Category: Warning indicator lights, such as fuel level indicator lights and windshield washer fluid level indicator lights. (3) Third Category: Fault indicator lights, including engine (exhaust system) fault lights, oil system fault lights, battery and power generation system fault lights, etc. These fault indicator lights rarely illuminate under normal circumstances.

What does OTA upgrade mean?

Automotive OTA upgrade refers to the system upgrade, each upgrade can bring improvements, fix vulnerabilities or obtain more functions, performance enhancements, or visual improvements, and this update is achieved by online detection after connecting to the internet, matching versions, downloading new code to the local device, and then executing installation, verification and other procedures. OTA first appeared in cars in 2012, when Tesla introduced the Model S with OTA technology for the first time, with updates covering modules such as human-machine interaction, autonomous driving, power, and battery systems. At that time, Tesla could use OTA to fix key card vulnerabilities, increase driving range, raise top speed, and improve ride comfort.

Does blackening the car emblem require registration?

Blackening the car emblem does not require registration. Car modification refers to altering the external appearance, internal styling, and mechanical performance of the original manufacturer's prototype vehicle according to the owner's needs. Below is an introduction to vehicle modifications: Modified components: Brake system: There are multiple methods for upgrading the brake system, such as installing larger brake discs, multi-piston brake calipers, and high-performance, high-temperature-resistant brake pads. Additionally, higher-grade brake fluid or metal high-pressure brake lines can be installed. Suspension system: Modifications to the suspension system mainly include replacing shock absorbers, reinforcing suspension structural bars, and installing stabilizer bars. Engine power: The engine is to a car what the heart is to a human—the most critical part of the vehicle. Intake system: The air filter on the engine is designed to filter the air required for engine operation.

What Causes Rear Axle Noise?

Rear axle noise is primarily caused by insufficient gear oil or decreased viscosity, swinging of the bevel driven gear, loose rivets, leading to inconsistent tooth side clearance and uneven meshing, which results in abnormal noise. The rear axle refers to the rear drive shaft component of a vehicle's power transmission system, consisting of two half-axles that allow for differential movement. Additionally, the rear axle serves as a device to support the wheels and connect the rear wheels. Detailed explanations of specific causes and corresponding solutions: Insufficient gear oil or decreased viscosity: If the issue is caused by this, it can be improved by changing the oil, ensuring adequate oil levels, switching from multi-grade oil to single-grade oil, or using oil with a higher viscosity grade. Noise due to gear tooth surface damage: Severe damage to the bevel gear tooth surface, excessive wear, or excessive clearance can cause a "humming" noise while driving, along with a metal friction sound that increases with speed. The noise noticeably weakens or disappears when coasting in neutral. If a sudden, intense, and rhythmic noise occurs while driving and disappears when coasting in neutral, it indicates severe tooth surface damage or broken teeth. In such cases, the gears should be repaired promptly or taken to a 4S shop for servicing. Noise caused by improper bearing clearance: If the bearing clearance is too small, there will be a uniform "humming" continuous sound. If the clearance is too large, there will be a chaotic "rattling" noise that increases with speed. High-speed noise accompanied by housing heat indicates excessive bearing preload adjustment. Noise during both acceleration and deceleration suggests bearing wear or excessive looseness. If rear axle noise is confirmed after inspection, it is recommended to visit a repair shop for handling.

Is the Smell of Tires Harmful to Human Health?

The smell of tires is not harmful to human health. During the production process of tires, certain gases are indeed generated that can be harmful to humans. However, advancements in production technology and protective measures for tire workers have effectively prevented these gases from harming workers' health. Once tires are finished products, they generally do not contain harmful gases. The pungent odor present in warehouses where tires are stored does not pose a health risk, although the smell can be quite unpleasant. Moreover, an increasing number of green factories and eco-friendly tires have achieved completely harmless production processes and technologies. Therefore, while the strong odor from tires is not harmful to human health, it is indeed unpleasant. If possible, try to avoid storing tires in living or office spaces.
