What does the EDC warning light on the car mean?

The EDC warning light on the car indicates a malfunction in the vehicle's high-pressure electronic injection and electronic control system, which means there is an issue with the engine. It is necessary to take the car to a 4S shop for professional inspection and repair by qualified technicians. Owners should not attempt to diagnose or fix the issue themselves to avoid causing further damage to the engine. If the EDC warning light comes on but the engine can start and run normally, the problem may not be severe—it could be due to damage in the engine's high-voltage circuit, fuel injectors, or oxygen sensors, leading to increased fuel consumption. However, if the engine fails to start normally, it is advisable to visit a 4S shop to check for potential faults in components such as high-voltage wires or spark plugs.

What does TRIP on a car mean?

TRIP on a car represents the trip mileage, which is convenient for users to calculate the kilometers of each trip. It can be reset to zero by long-pressing the clear button. The minimum unit of trip mileage TRIP is 0.1 kilometers, and the basic calculation method is to divide the actual fuel consumption by the actual mileage traveled. In contrast, ODO stands for the total mileage, which cannot be reset. The car's RESET and TRIP buttons are generally located on the multifunction steering wheel, and some models may place them on the left side of the driver's seat, but the positions vary. RESET literally translates to reset, and its function is basically to reset the information in the car's dashboard information center, except for the total mileage.

What Causes Abnormal Noises When Driving a Car?

Reasons for abnormal noises when driving a car: Excessive tire pressure leads to tread wear, reduced damping performance of the tires, and consequently increased tire noise. Worn or loose wheel hub bearings. Uneven friction between the crown and the ground. Solutions: Check if the car's chassis screws are loose, inspect whether the bonding adhesive on the lower arm of the site is loose. Examine the vehicle's oil condition. If oil is lacking, replenish it promptly. Verify if the valve clearance is adjusted to the appropriate position; if displaced, adjust the position. Engine maintenance is crucial. The engine accumulates a lot of grease, which should be cleaned promptly to prevent it from affecting the engine's normal operation. Cleaning grease requires attention: Use a damp cloth to wipe off the grease; if it can be cleaned by wiping, avoid using water for washing. Secondly, ordinary damp cloths may not clean the grease off the engine thoroughly; try using detergent for wiping. Finally, if it still cannot be cleaned, use water for washing, ensuring that components that should not get wet are wrapped up before rinsing.
