What is the reason why the dome light of the 2018 Trumpchi GS4 does not automatically light up?

What Does Insufficient Oil Pressure Mean?

When the engine oil pressure is insufficient, the main reasons are as follows: 1. The engine oil storage is too low, causing the lubrication system to have no oil or insufficient oil: refill the oil in time to ensure sufficient oil storage. 2. The oil is dirty or too viscous, preventing the oil pump from effectively sucking and pumping the oil: the oil needs to be replaced promptly. 3. The oil is too thin or becomes thin due to high engine temperature: thin oil may leak from the gaps between the engine's friction pairs, leading to insufficient oil pressure. It is necessary to replace the oil or repair the cooling system in time. 4. The oil pressure sensor is damaged: the normal oil pressure range should be maintained between 150～350kPa.

How to Solve Gear Grinding in Cars?

Gear grinding is essentially the direct collision between two metal gears, which ultimately leads to accelerated wear on the gear teeth. Over time and with frequent occurrences, the originally right-angled gear teeth become rounded, resulting in incomplete engagement after shifting. The solutions for gear grinding in cars are as follows: 1. First, bring the car to a complete stop before shifting gears. 2. Then, depress the clutch pedal fully. Measures to avoid gear grinding include: 1. Inside a manual transmission, there is a crucial component called the 'synchronizer.' The synchronizer's role is to match the speed of the gear being shifted into with the output gear's speed during a shift, preventing gear grinding. 2. When reversing, it is necessary to bring the vehicle to a complete stop to reduce the speed difference between the power output and the reverse gear, ensuring smooth engagement without gear grinding.

What are the causes of body vibration when the vehicle speed is between 60 and 80?

When the vehicle speed is between 60 and 80, the causes of body vibration are as follows: 1. It is caused by the aging or damage of the engine or transmission mount pads. Replacement can eliminate the issue. 2. Damage to the chassis half-shaft or drive shaft; this mostly occurs during acceleration or deceleration conditions. 3. The tire and rim require dynamic balancing, or the tire may be aging and deformed, or the rim may be deformed. Perform tire dynamic balancing as needed to check the condition of the tire and rim. When the car accelerates from 60 mph to 80 mph, the front body vibrates, but it does not vibrate when the accelerator is not pressed, nor does it vibrate at other speeds. This is caused by excessive clearance in the front suspension ball joint or connecting components, which creates vibration at a certain frequency. It is necessary to go to a repair shop to adjust the toe-in and front wheel alignment.

How to reset the tire pressure warning on Dongfeng Fengshen AX7?

Dongfeng Fengshen AX7 tire pressure warning reset methods are as follows: Abnormal tire pressure: The system typically triggers a warning when pressure falls below 1.8bar or exceeds 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system isn't reset promptly, it continues to record the previous data, causing the tire pressure warning light to illuminate. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), it will trigger the tire pressure warning light. For sensor damage issues, replacement with a new component is the only solution. Tire pressure monitoring automatically checks tire pressure in real-time while driving, alerting drivers to leaks or low pressure to ensure driving safety.

How to Force Brake with Electronic Handbrake?

Electronic handbrake can be forced to brake by pulling the button to send a brake signal to the vehicle's computer, then holding the electronic handbrake button up for 3 seconds. The vehicle's computer will automatically determine that the vehicle needs to force brake and then issue a command to the ESP body stability control system to perform a special emergency brake. Electronic braking mainly relies on the ECU vehicle computer to make judgments and issue commands to the vehicle. By pulling up and pressing the button, the vehicle makes a brake signal. Many car models now adopt electronic braking design. Electronic handbrake is a technology that achieves parking brake through electronic control. Its working principle is the same as that of mechanical handbrake, both of which achieve parking brake control through the friction generated by the brake disc and brake pads, except that the control method has changed from the previous mechanical handbrake lever to an electronic button. Electronic Parking Brake (EPB) refers to the integration of temporary braking during driving and long-term braking after parking, and the technology of achieving parking brake through electronic control. Electronic handbrake extends from the basic parking function to the automatic parking function AUTOHOLD. The application of AUTOHOLD automatic parking function technology allows drivers not to brake for a long time when the vehicle stops. Starting the automatic electronic parking brake can avoid unnecessary sliding of the vehicle.

How to reset the tire pressure light on Dongfeng Honda?

Dongfeng Honda tire pressure light reset method is as follows: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "ding" sound, then release. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally the dashboard warning light will turn off, completing the tire pressure reset. There are generally three reasons for the tire pressure light to illuminate: Abnormal tire pressure: The system usually triggers an alarm when pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the system continues to record the previous data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), it will also cause the tire pressure warning light to illuminate. For sensor damage issues, replacement with a new component is the only solution.
