First, the voltage at the wiring connector is abnormal; second, there is a short circuit in the daytime running light circuit; third, the bulb is damaged. Below is an introduction to daytime running lights: Introduction: Daytime running lights (DRLs) are installed on the front sides of the vehicle to signal its presence to others during the day. Function: DRLs are not for illuminating the road for the driver but to alert others that a vehicle is approaching, falling under the category of signal lights. Specifications: According to standards, daytime running lights must be white in color, and their chromaticity characteristics must meet specified requirements.

What is the difference between the Eco mode and Normal mode in the Haval H6?

Harvard H6's Eco mode and Normal mode mainly differ in terms of power and fuel consumption. Eco mode: Slightly weaker power but lower fuel consumption, effectively saving fuel. Suitable for empty loads, flat roads, and low-speed urban driving. It maintains the lowest possible engine speed to save fuel, such as around 1400 RPM. In contrast, Sport mode keeps the engine speed around 2000 RPM or higher to maintain the optimal shifting speed. Normal mode: Suitable for daily use with normal power and moderate fuel consumption. It works well for most situations except for heavy loads or uphill driving.

Can a car that hasn't been inspected for three years still undergo inspection?

A car that hasn't been inspected for three years cannot undergo inspection anymore. Time period: No penalty will be imposed for being one day overdue. Vehicles that exceed the inspection period by less than one year can apply for a supplementary inspection at the vehicle management department without facing penalties. However, if the inspection period is exceeded by more than one year, a penalty of 3 points deduction will be imposed, and the vehicle may be temporarily impounded. Penalties: For motor vehicles driven on the road without displaying the inspection qualification label, the vehicle will be impounded, and 1 point will be deducted. If compulsory traffic insurance has not been purchased, a penalty of twice the insurance premium amount will be imposed. Below is extended information related to engines: Energy conversion: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. Device: An engine can refer to either a power generation device or the entire machine including the power device (e.g., gasoline engines, aircraft engines). The engine was first invented in the UK, so the concept of an engine also originates from English, with its original meaning referring to "a mechanical device that generates power."
