Why does the reversing camera show no signal when shifting into reverse gear?

The reasons for the reversing camera showing no signal when shifting into reverse gear: Poor line contact, it is necessary to check the line and the wiring connection of the whole vehicle in time to see if there is a loose connection. If there is, it will cause the reversing camera to work intermittently, or even directly black screen. At this time, just connect the loose part properly. Various fault phenomena of the reversing camera are still closely related to the installation process, after all, this project needs to deal with relatively complex lines. If you really need to replace the reversing camera, it is better to leave it to professionals, otherwise, if the installation is unprofessional or wrong, it is likely to cause the failure of the reversing camera, not only the display problem, but also certain safety hazards.

How to Add Antifreeze to a 4.2-meter Truck?

For this type of truck, the radiator is located behind the left front wheel. If you need to replace or add antifreeze, you will need to lift the cab. The radiator is part of the cooling system, where the engine relies on the continuous circulation of coolant to dissipate heat. Below are the precautions for adding antifreeze: 1. Brand Selection: Try to use the same brand of antifreeze. Different brands of antifreeze use different metal corrosion inhibitors, so they should not be mixed. 2. Expiration Date: Most antifreeze products have a validity period of two years (some products may last longer). When adding antifreeze, ensure the product is within its expiration date. When replacing, drain the old fluid completely, clean the cooling system thoroughly, and then add the new fluid. 3. Do Not Dilute with Water: Avoid diluting antifreeze with water. Traditional inorganic antifreeze should not be diluted with water, as it can cause sedimentation, severely affecting the antifreeze's normal function. Organic antifreeze can be diluted with water, but excessive dilution should be avoided.

Why does the battery light come on and the car won't start?

The reason the car won't start and the battery indicator light is on is that the battery is depleted and needs to be replaced. Here are some methods to extend battery life: 1. Regular battery usage: Many cars use lead-acid batteries. If the car remains idle for extended periods, the sulfuric acid inside will settle, leading to natural discharge. Prolonged occurrences of this will result in insufficient power supply and significantly reduce battery lifespan. 2. Clean the battery terminals: The area around the terminals isn't completely sealed. When the car is running, movement can cause electrolyte to leak from the terminals. This electrolyte can undergo chemical reactions in the air, affecting the battery's normal operation. 3. Regularly check the alternator: Since the battery relies on the alternator for charging, any issues with the alternator will greatly impact the battery. This not only causes insufficient power supply but also continuously drains the battery's durability, so special attention should be paid to the alternator as the source.

What are the wrong practices when a vehicle has a tire blowout?

The wrong practices when a vehicle has a tire blowout are applying emergency braking and jerking the steering wheel. The correct approach is as follows: 1. Correct response to a sudden tire blowout: Firmly grip the steering wheel with both hands to maintain control, release the accelerator pedal, try to follow the intended path, and then apply intermittent and forceful braking to slow down until coming to a smooth stop. 2. Causes of tire blowouts: (1) Abnormal tire pressure: Including excessive or insufficient pressure. Continuing to drive under such conditions can lead to abnormal tire compression and wear, increasing the risk of a blowout. (2) Bulges or cracks on the tire sidewall: Since the sidewall is the weakest part of the tire, any bulges or cracks compromise the tire's designed strength, posing a blowout risk if driving continues. (3) Severe tire aging: Generally, tires are made of rubber and have a lifespan of three to five years. Beyond this period, the rubber may age and develop cracks, increasing the risk of a blowout. (4) Severe tire wear: Tires have wear limits. Exceeding these limits means the tire's strength can no longer meet safety requirements, potentially leading to a blowout.

How to Handle Speeding Less Than 20%?

Speeding less than 20% results in different penalties depending on the road type, as detailed below: 1. Driving medium-sized or larger passenger or cargo vehicles, or dangerous goods transport vehicles: On roads other than highways or urban expressways, or driving other motor vehicles exceeding the speed limit by less than 20% will result in a 3-point deduction. 2. Driving medium-sized or larger passenger or cargo vehicles, school buses, or dangerous goods transport vehicles: On highways or urban expressways, exceeding the speed limit by less than 20% will result in a 6-point deduction. The penalties for speeding 20% or more are as follows: 1. Driving medium-sized or larger passenger or cargo vehicles, school buses, or dangerous goods transport vehicles: On roads other than highways or urban expressways, or driving other motor vehicles exceeding the speed limit by 20% to less than 50% will result in a 6-point deduction. 2. Driving medium-sized or larger passenger or cargo vehicles, school buses, or dangerous goods transport vehicles: On highways or urban expressways exceeding the speed limit by 20% or more, or on roads other than highways or urban expressways exceeding the speed limit by 50% or more, or driving other motor vehicles exceeding the speed limit by 50% or more will result in a 12-point deduction.

Does a damaged car door count as an accident vehicle?

A car with a damaged door that requires replacement will be classified as an accident vehicle. Relevant details are as follows: 1. Definition of an accident vehicle: A vehicle that has suffered damage from non-natural wear and tear accidents, resulting in decreased mechanical performance and economic value, is considered an accident vehicle. 2. The following situations qualify as accident vehicles: (1) Vehicles with damage to the engine compartment or passenger compartment due to impact. (2) Vehicles with rear quarter panel damage exceeding one-third of its area. (3) Vehicles with welded, cut, reshaped, or deformed longitudinal beams. (4) Vehicles with welded, cut, reshaped, or deformed shock absorber mounts. (5) Vehicles with welded, cut, reshaped, or deformed A, B, or C pillars. (6) Vehicles whose airbags deployed due to impact. (7) Vehicles with severe welding, cutting, reshaping, or deformation in other non-removable parts. (8) Vehicles with water immersion exceeding half of the body height or water entering the passenger compartment. (9) Vehicles with fire damage exceeding 0.5 square meters that still pose safety hazards after repairs.
