Check the wiring connections of the reverse radar and the installation points on the vehicle to see if there are any loose connections—poor contact can cause the reverse radar to intermittently function. Below are the reasons for automotive radar system failures: No alarm from the reverse radar system: The symptom is that there is no response when shifting into reverse gear or pressing the radar switch. The diagnosis is that the working power ground circuit of the reverse radar system is not functioning. Reverse radar system not activated: A common cause is that the parking assistance conditions are not met, meaning the vehicle is in park mode or trailer mode, requiring replacement of the reverse radar or reactivation. Radar system indicates a fault: The symptom is that the radar system indicates a fault when using the parking function. The diagnosis is a faulty sensor or an abnormal connection between the sensor and the controller; replace the controller or sensor.

Does 'E' Mean Having Fuel or Not?

E indicates no fuel, while F means sufficient fuel. When the vehicle is low on fuel, the dashboard will illuminate a fuel warning light, which typically appears as a fuel tank icon. When fuel is low, the warning light will turn yellow; when fuel is critically low, it will turn red. Some vehicle models only display a yellow warning light. The impacts of low fuel levels include: 1. Fuel sloshing causing the engine to stall: When the fuel level is too low, fuel can slosh in bumpy or winding roads; 2. Fuel pump overheating: The fuel pump relies on fuel for cooling. If fuel levels are too low, the cooling efficiency decreases, accelerating wear on internal components and potentially causing short circuits or burnout; 3. Clogging the fuel system: Sediments at the bottom of the fuel tank can enter the fuel supply system due to fuel sloshing when levels are low, leading to blockages in the fuel lines.

Formula for Vehicle Purchase Tax?

Vehicle purchase tax = vehicle price excluding tax * vehicle purchase tax rate. The current vehicle purchase tax rate is 10%, and the VAT rate is 13%. The specific calculation formula is: vehicle purchase tax amount = vehicle price including tax / 1.13 * 10%. The following are the characteristics of vehicle purchase tax: 1. Single scope of taxation: As a property tax, the vehicle purchase tax is levied on specific vehicles purchased, rather than on all property or consumer goods. It has a narrow scope and is a type of special property tax. 2. Single collection point: The vehicle purchase tax is levied only once. It is not collected at every stage of production, operation, or consumption, but only at the specific point when the vehicle exits circulation and enters the consumption field. 3. Single tax rate: The vehicle purchase tax is levied at a single uniform proportional rate. The rate does not vary with the amount of the taxable object, making the calculation simple and the burden stable, which is conducive to tax administration according to law.
