What does the flashing yellow light of Mazda i-stop mean?

i-STOP refers to the Intelligent Idling Stop System. A flashing yellow i-stop light indicates that the start-stop system is turned off or there is a malfunction. Reasons for i-STOP malfunction: The flashing yellow i-stop light is usually caused by insufficient battery charge, lack of engine oil, or insufficient coolant. i-stop is an idling stop system that significantly improves fuel economy and provides a natural driving feel. How to use i-STOP: While driving, simply press the brake pedal. The engine will automatically shut off approximately two seconds after the vehicle comes to a complete stop. Keeping the brake pedal pressed will maintain the engine in the off state. As soon as you release the brake or turn the steering wheel, the engine will immediately restart automatically, allowing you to press the accelerator and start moving again—all while remaining in D gear throughout the entire process.

Why does the new car's window glass make a screeching noise when rolling up and down on rainy days?

The reasons for abnormal noise during the window glass rolling up and down include foreign objects in the rubber guide rail, etc. Below are the specific reasons for the abnormal noise during window glass rolling up and down: 1. Dirty rubber guide rail of the door glass: The rubber guide rail of the door glass tends to accumulate dust, causing abnormal noise when the glass rolls up and down. In this case, you can first clean the dust in the rubber guide rail with water, dry the moisture, and then spray a little rubber protectant or lubricant on the rubber guide rail. The noise during glass rolling will then disappear. 2. Aging rubber guide rail of the door glass: The rubber guide rail of the door glass is exposed to sun and rain all year round, making it prone to aging and losing elasticity. When the glass rolls up and down, friction with the aged rubber guide rail will produce abnormal noise. This situation can only be resolved by replacing the rubber guide rail with a new one.

What does it mean when the parking assist system stops working?

The reasons for the parking assist system stopping operation are as follows: 1. Damaged sensor or bumper: The sensor is blocked by components installed on the vehicle, such as the bumper cover. 2. Use of a temporary spare tire: The vehicle is used to transport loads exceeding its capacity. Below is relevant information: 1. Parking assist system: This includes ultrasonic sensors embedded in the front and rear bumpers, each with a diameter of about 15mm. The ultrasonic detection signals emitted by the sensors reflect when they encounter obstacles. Upon receiving the reflected signals, the sensors promptly feed them back to the system for distance calculation, alerting the driver through sound or video about the distance to obstacles outside the field of vision. 2. Fault symptoms: After receiving the vehicle, a test drive confirmed the fault. Upon turning on the ignition and starting the engine, shifting the transmission into R gear revealed that the red indicator light on the parking assist system (PTS) button lit up, and neither the front nor rear parking warning indicators responded, indicating that the parking assist system was in a disabled state.

Can the transmission be replaced?

The transmission can be replaced, but it needs to be done at a repair shop. Below is relevant information about transmissions: 1. AT Transmission: Early powertrain systems mainly used 4AT, but have since developed towards multi-speed directions such as 6AT and 8AT. AT transmissions feature smooth shifting, good comfort, and strong power transmission capability, but they have poor fuel economy and high manufacturing costs. 2. AMT: Based on traditional manual transmissions, AMT only changes the manual operation part, achieving automatic shifting through an electronically controlled automatic operating system. AMT has a simple structure, low cost, and good fuel economy, but its comfort is poor, and automated control is challenging. 3. CVT: A true continuously variable transmission, CVT has fewer parts and a compact size, offering high efficiency and low fuel consumption. It can also serve as a power coupling and transmission for hybrid vehicles. However, it has drawbacks such as complex manufacturing, high investment, and the susceptibility of the transmission belt to damage and short lifespan.

What are the common issues when motorcycle spotlights fail to light up?

It is a failure in the lighting signal system. The failure rate of motorcycle lighting signal systems is relatively high. The main causes of failure include: loose wire connections, poor contact, short circuits, ground wire breaks, and excessively high voltage adjustment of the voltage regulator. Common diagnostic methods include the spark test method, ground spark test method, or power short-circuit method. More details are as follows: 1. Front headlight not lighting up: The main reasons for the front headlight not lighting up are: broken power wires, poor ground wire contact, blown fuses in the circuit, burnt-out filaments, poor contact between the bulb base and socket, or faulty/damaged contacts in the light switch. 2. Incomplete high/low beam function: Some motorcycles may lack either high beam or low beam functionality. If the light switch is set to the headlight position and only the high beam works while the low beam does not, or vice versa, this is referred to as incomplete high/low beam function in the headlight.

What does fuel cap open mean?

It indicates that the fuel tank cap of the vehicle is not properly closed, and it is recommended to check the fuel tank cap. The information and functions of the fuel tank cap are introduced as follows: 1. Drainage hole: The inclined design of the fuel tank opening is not for aesthetics but for environmental considerations to prevent rainwater accumulation. 2. Tire pressure value: Tires are the part of the car that directly contacts the ground, and their condition determines the driving safety. Generally, the safety of a tire can be judged by its air pressure and wear level. Many cars now have a label on the fuel tank cap that specifies the recommended tire pressure values under different loads. 3. Fuel grade: Since it is the fuel tank cap of the car, it naturally includes information about the fuel. If you want to know what grade of gasoline your car should use, you can find this information on the fuel cap. There are regulations on what grade of gasoline a car should use. Using a higher grade than necessary is not only unnecessary but also a waste of money, while using a lower grade can damage the engine's performance.
