Reversing camera not lighting up may be due to power supply issues, prolonged use leading to circuit aging, and other reasons. Here are detailed explanations and solutions: Power Supply Issues: Third-party software incompatibility with the system or outdated software versions may cause system failure and abnormal display, or screen damage. It is best to have a professional inspection at an after-sales service center to identify the specific cause. Prolonged Use: Black screen caused by circuit aging due to prolonged use. If there is no image but sound remains, it might be due to a loose power connector of the navigation display. If there is no sound or image at all, the DVD might be damaged. Solutions include reconnecting the power connector or replacing the DVD.

I've repaired many car reversing camera issues, mainly due to several reasons: The most common is camera failure itself, such as the lens being covered by mud or damaged by water ingress, resulting in a completely black screen. Secondly, wiring connection problems, like harness breakage from frequent trunk opening/closing or loose plugs, can affect signal transmission. Then there's the host system failure, possibly due to software crashes or host overheating. Fuse burnout is also a common factor—if the reversing circuit overloads and blows the fuse, the camera won't display. Additionally, a faulty reversing switch can prevent system activation. I recommend owners start with simple checks: inspect camera cleanliness and the fuse box. If DIY isn't feasible, promptly visit a professional repair shop—delaying compromises reversing safety, especially riskier at night. Remember to clean cameras and inspect wiring during regular maintenance to prevent issues proactively.

It also provides vehicle-related services such as refueling, traffic violation alerts, and parking spot photo-based car finding. Beyond car connectivity, Huawei HiCar can integrate with home systems, allowing you to remotely check and control home devices like windows, doors, lights, curtains, and air conditioning while in your car. Installing Huawei HiCar in regular vehicles: You can purchase a HiCar connection box online and install it on your car's infotainment system. Note that the original car system must run on Android to support HiCar functionality. If the connection box doesn't work, you can alternatively install a Huawei Smart Screen in your vehicle to enable HiCar features. Currently, Huawei HiCar is primarily designed for installation in new vehicles, so existing cars would require retrofitting the HiCar system.

Does it matter if the engine oil hasn't been changed for a year and a half, with low mileage?

Even the best engine oil will deteriorate after one year of use. Full synthetic oil should be replaced even if the mileage hasn't been reached. The impacts are as follows: 1. Possible insufficient oil volume: The engine continuously consumes oil during operation, though at a relatively slow rate. As long as there's no oil burning, oil shortage generally won't occur within the normal oil change interval. However, in certain situations like vehicle deceleration, bumpy roads, or body tilting, the oil pump may not be able to draw oil properly. 2. Accelerated oil aging: Engine oil not only provides lubrication but also cooling. Although the heat absorbed by the oil is ultimately dissipated through the engine and coolant, insufficient oil volume reduces the efficiency of heat dissipation, potentially leading to higher oil temperatures and faster oil degradation. 3. Increased engine sludge: Prolonged oil change intervals result in reduced oil volume while the engine continues to operate, generating particles continuously. These particles keep dissolving in the oil until the oil becomes increasingly viscous. 4. Potential oil filter failure: The oil filter is designed to remove impurities from the oil. After leaving the oil pump, the oil passes through the filter before reaching components requiring lubrication. After lubrication, the oil returns to the oil pan and is drawn back into the oil pump, passing through the filter again.

Does an AT Transmission Slip Require an Overhaul?

Slipping must be repaired; driving should not continue. Below is relevant information: 1. Transmission: A device that changes the speed ratio and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a casing and several pairs of gears. 2. Definition: A transmission is a gearbox that changes the transmission ratio and direction of motion. It is located between the clutch and the central drive. Its main functions are: changing the vehicle's driving force and speed (shifting) without altering the engine's speed and torque; enabling the vehicle to reverse (direction change); and allowing the engine to idle without stalling (neutral). Based on the transmission type, gear transmissions can be divided into three types: two-shaft, three-shaft, and compound. The two-shaft type has two main shafts (excluding the reverse shaft) and only undergoes one pair of gear reduction. The three-shaft type has three main shafts (first shaft, intermediate shaft, second shaft) and undergoes two pairs of gear reduction. The compound type consists of two transmissions connected in series or parallel to achieve more gear positions with fewer gears.
