The reasons for the barrier gate not lowering include the triple button being set to manual mode, the ground sense processor of the barrier gate crashing, issues with the ground sense coil, failure of the barrier gate's mainboard, or interference from other peripherals. Below are the detailed explanations: 1. Measures: Set the triple button to automatic mode; check if the OUTPUT indicator light on the ground sense processor of the barrier gate is flashing green rapidly; restart the barrier gate's power supply to see if it returns to normal. If not, replace the ground sense processor, measure the continuity of the ground sense coil; replace the barrier gate's mainboard for testing; disconnect and test the wiring to the card reader. 2. No response when the card reader is powered on: Check the two power supplies (12V and 24V) separately, see if the power indicator light on the card reader's mainboard is lit, and check for any burned or overheating electronic components.

Why is the Audi car burning water?

Audi cars burn water due to reasons such as insufficient coolant, thermostat failure, and insufficient internal pressure in the engine oil tank. The specific details are as follows: Coolant Leakage: First, determine if there is a coolant leak. If the coolant is leaking, it needs to be repaired and the coolant replenished promptly. If there is no coolant leakage, as the temperature rises, the water vapor inside the water passages pushes the coolant out of the replenishment tank due to the increased water temperature. Thermostat Failure: This is caused by poor performance of the pump or thermostat, leading to excessively high water temperature in the circulation system, which causes the coolant in the tank to overflow from the radiator cap or the replenishment tank. Insufficient Internal Pressure in the Engine Oil Tank: If the internal pressure in the engine oil tank does not reach the predetermined level while cooling the car, stepping on the accelerator causes the coolant to surge out from the radiator and replenishment tank outlets, a fault phenomenon caused by the radiator cap spring being too soft.

Can the rear seats of the Trumpchi GS4 be laid flat for sleeping?

The rear seats of the Trumpchi GS4 can be laid flat for sleeping. There is a release handle located in the middle of the seat back; pulling this handle outward will allow the seats to fold down completely. The Trumpchi GS4 is a 5-door, 5-seat compact SUV with the following dimensions: length 4545mm, width 1856mm, height 1668mm, and a wheelbase of 2680mm. It has a fuel tank capacity of 55 liters and a trunk capacity of 470 liters. The GS4 is powered by a 1.5T turbocharged engine, delivering a maximum horsepower of 169PS, a maximum power output of 124kW, and a peak torque of 265Nm, paired with a 6-speed manual transmission.

What are the maintenance items for a vehicle?

Vehicle maintenance items include: 1. Check whether the tire pressure is normal and whether there is uneven wear, bulging, or damage to the tires; 2. Inspect the car chassis, including brake pads, brake discs, connecting rods, ball joints, and CV joints for any scratches; 3. Replace the engine oil and oil filter, clean the air filter, and check whether the generator belt and wiper blades are damaged; 4. Check whether the levels of various fluids are normal; 5. Inspect all switches and lights to ensure they are functioning properly. Maintenance precautions are: 1. Make an appointment in advance; 2. Record any malfunctions or questions encountered while driving and inform the staff during the maintenance registration.

What does it mean when a vehicle displays TCS?

When a vehicle displays TCS, it indicates a malfunction in the Traction Control System. Use a decoder to read the specific fault code and proceed with repairs based on the fault code's instructions. TCS, or Traction Control System, is also known as the Track Control System. Its components include: ECM (Engine Control Module), TCM (Transmission Control Module), TCS computer, ABS computer, and wheel speed sensors. The working principle of TCS is: it relies on electronic sensors to detect when the speed of the driven wheel is lower than that of the driving wheel, and it automatically adjusts ignition timing, reduces throttle opening, decreases throttle input, downshifts, or applies brakes to the wheels to prevent wheel slip.

What are the symptoms of a broken front shock absorber?

The symptoms of a broken front shock absorber include: 1. The shock absorber makes abnormal noises when the vehicle is driving on bumpy roads; 2. There is oil leakage on the exterior of the shock absorber; 3. The vehicle body shakes and becomes unstable when driving on bumpy roads; 4. The shock absorber casing becomes excessively hot after driving. The working principle of the shock absorber: When relative motion occurs between the frame or body and the axle due to vibration, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different pores. The friction between the pore walls and the oil, as well as the internal friction between oil molecules, creates a damping force that converts the vehicle's vibration energy into thermal energy of the oil, which is then absorbed by the shock absorber and dissipated into the air.

What are the reasons for the drop in water temperature while driving?

The reasons for the drop in water temperature while driving are: 1. Damaged thermostat; 2. Faulty radiator fan running continuously; 3. Faulty water temperature sensor; 4. Wiring issues; 5. Malfunctioning dashboard water temperature gauge. The solutions for a drop in car water temperature include: 1. Replacing the thermostat and radiator fan; 2. Repairing the water temperature sensor; 3. Checking the wiring for integrity; 4. Resetting the car system by disconnecting the battery; 5. Inspecting the cooling system for leaks and ensuring the water pump is functioning properly. Methods to prevent water temperature from dropping or rising: 1. Avoid prolonged use of air conditioning; 2. Regularly clean the radiator and condenser; 3. Periodically check the thermostat's working condition.
