What is the reason for the OFF light being on?

1 Answers

The OFF light on a car mainly refers to the ESP-OFF. ESP stands for Electronic Stability Program, which is an active safety device designed to prevent the vehicle from skidding or fishtailing. The ESP is automatically enabled by default, and the OFF button is in the off state. If the OFF button is lit, it means the ESP has been turned off. There are usually several reasons for this: 1. Accidental button press: Accidentally touching the OFF button can cause it to light up. Pressing the button once briefly will re-enable the ESP. 2. Wiring fault: A short circuit or damaged wiring can affect the normal operation of the OFF button, requiring inspection and repair at a 4S shop. 3. Sensor damage: If the sensor malfunctions, the OFF button may not respond, necessitating immediate repair at a service center. 4. Electronic control unit signal error: A signal fault can cause the OFF button to fail, requiring immediate inspection and repair. 5. Low battery: When the battery is low on power, the OFF button may be difficult to activate, and the vehicle should be charged promptly.

Which Direction Do Car Wheel Nuts Turn?

The direction of car wheel nuts: 1. For passenger cars, the wheel nuts loosen counterclockwise: Place your left hand facing the center of the wheel, and use your right hand to lift the wrench upward to loosen the nut. 2. For large trucks, the wheel nuts on the left and right sides turn differently. The left side (driver's side) has reverse threads, while the right side has standard threads. This means tightening follows the vehicle's forward rolling direction, while loosening follows the reverse direction. Introduction to tires: 1. Tires are circular elastic rubber products mounted on various vehicles or machinery that roll on the ground. 2. Tires are installed on metal rims to support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance.

Does a car have a break-in period?

New cars do have a break-in period. The following are precautions for the break-in period of a new car: Avoid high-speed driving: Try not to let the car's speed reach 120km/h, as this can help maintain the engine's performance and extend its lifespan. Avoid overloading: Placing excessively heavy objects in the car during the break-in period undoubtedly puts pressure on the vehicle. Overloading often requires frequent gear changes, and the constant shifting between high and low gears can be very damaging to the engine. Avoid driving on extremely poor road conditions: Driving on very rough roads during the break-in period can cause significant wear on the tires. Additionally, prolonged driving under such conditions with the engine constantly operating at high power can inevitably lead to damage.

Does a Rear-End Collision Count as an Accident Vehicle?

Currently, there is no standardized definition for what constitutes an accident vehicle, and perspectives vary slightly among different industry professionals. For instance, used car dealers typically only classify vehicles involved in major accidents as accident vehicles, while some sectors adopt much stricter criteria, where even minor scratches or dents may qualify a car as an accident vehicle. Below are some common criteria for identifying accident vehicles: 1. Engine Compartment Damage: Vehicles that have sustained damage to the engine compartment or passenger compartment due to impact. 2. Rear Quarter Panel: Vehicles where the rear quarter panel has been damaged by impact exceeding one-third of its area. 3. Frame Rails: Vehicles with welded, cut, reshaped, or deformed frame rails.

What is the purpose of a three-way catalytic converter?

The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Simply put, its function is to purify exhaust gases. The working principle of the three-way catalytic converter: 1. When engine exhaust gases pass through the exhaust pipe, the catalytic action of the purifying agent in the three-way catalytic converter enhances the activity of CO, HC, and NOx, facilitating oxidation and reduction reactions. 2. CO is oxidized into colorless, non-toxic CO2 at high temperatures, HC compounds are oxidized into H2O and CO2 at high temperatures, and NOx is reduced into N2 (nitrogen) and O2 (oxygen), thereby purifying the engine's exhaust emissions.
