The method for adding automotive refrigerant is: 1. Prepare tools and materials such as an automotive refrigerant recovery and charging machine and refrigerant; 2. Connect the pipelines of the automotive refrigerant recovery and charging machine to the high and low pressure pipes of the car's air conditioning system; 3. Perform a vacuum process on the car's air conditioning system; 4. Set the charging capacity, time, and type on the refrigerant recovery and charging machine; 5. The refrigerant recovery and charging machine will automatically start adding the refrigerant. The methods to determine whether a car needs refrigerant are: 1. If the air conditioning reaches the set temperature quickly after being turned on for a while, it indicates normal operation, otherwise refrigerant oil needs to be added; 2. Use a thermometer to measure the temperature difference between the air inlet and outlet of the indoor unit. If the difference is less than about 8 degrees Celsius, refrigerant oil needs to be added.

Why is the ETC light not on?

The reason why the ETC working light is not on may be due to ETC device damage or insufficient power. The ETC device relies on solar charging. You can park the vehicle in a sunny place for a while, reinsert the card once, and check whether the device display can function normally. If there is still no response, please go to a service outlet for troubleshooting, repair, or replacement. More details are as follows: 1. As for how to test ETC sensing, since general users do not have specialized signal testing equipment, it is difficult to do so. The simplest ETC signal testing method is to drive the vehicle into the ETC lane at a speed of less than 20km/h. If the sensing distance is 8-10 meters, it indicates good signal. 2. As for how to test ETC with a mobile phone, in fact, mobile phones with NFC function have ETC card reading function and can also be used for ETC card recharge, but generally cannot test ETC device signals.

What Causes Tire Vibration?

Tire vibration causes introduction: Excessive or insufficient tire pressure: Once the vehicle speed is relatively high, the body vibration amplitude increases, and the tires will also vibrate accordingly. Abnormal tire wear. Due to wheel alignment or rim deformation, the tire surface wears unevenly, causing body vibration during driving. Uneven brake disc surface: During braking, the contact between the brake pads and the brake disc is discontinuous, resulting in fluctuating braking force, which can also cause tire vibration. Large deviations in the four-wheel alignment data of the wheel tires, such as issues with the front wheel alignment angle data, can lead to wheel hub deformation and abnormal wear, causing tire dynamic balance failure and resulting in certain vibrations during driving. Damaged shock absorbers: If the shock absorbers lose their effectiveness, the impact of the road on the tires will be more significant, leading to greater tire vibration. Half-shaft resonance. This situation is usually caused by a bent half-shaft (in front-wheel-drive vehicles) or drive shaft (in rear-wheel-drive vehicles).
