What is the reason for the leakage problem in Zotye SR7?

Zotye SR7 leakage problem is caused by circuit faults and leakage of electronic components. The following is a related introduction about the leakage problem of Zotye SR7: Circuit fault: Short circuit or oxidation shedding of the battery plates leads to self-discharge and power loss, which is caused by the internal discharge of the battery. This reason is an important indicator related to the quality of the battery itself. At this time, you can go to the 4S shop to find professionals to check the battery circuit. Leakage of electronic components: Due to the grounding of automotive electrical appliances, wiring harnesses, sensors, controllers, actuators and other electronic components and circuits, leakage causes battery power loss. Moreover, this kind of leakage is a latent circuit fault, which must be investigated. Find and replace the relevant electronic components in time. Method to find leakage: Set the multimeter to AC 20A, insert the red wire into the 20A hole, then use iron wire to connect the positive and negative poles of the multimeter between the negative pole of the battery and the grounding wire, then remove the connection line of the negative pole of the battery with a fork wrench, after connecting all the lines, turn on the power of the multimeter, you can see the current, then open the fuse box in the engine compartment, take out the fuse inside, if the current suddenly drops, then the line and equipment connected to this fuse have leakage. Then pull out this power-saving fuse, the voltage drops directly from 1.46 to 0.22, pull out the 30A one drops 0.09, then pull out the 40A one the voltage drops to 0.00.

What is the ETC system on expressways?

ETC is an electronic toll collection system, also known as an automatic road toll system. It is a road toll method specifically designed for toll roads, commonly seen on expressways, bridges or tunnels with toll policies, and certain sections of city centers to alleviate urban traffic congestion. According to regulations from the State Council, starting from 2020, vehicles without ETC cannot enjoy toll discounts. In the future, expressway toll stations will retain only one manual lane, and tolls can only be paid through manual channels. Additionally, newly installed ETC devices cannot be used on expressways immediately; they must be activated first. During free holiday periods, vehicles with ETC can still use expressways, and no fees will be deducted when passing through ETC lanes. ETC Deduction Principles: Expressways have one or more ETC lanes. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and by using computer networking technology for backend settlement with banks, the system achieves the goal of allowing vehicles to pay tolls without stopping at road or bridge toll stations. All of this operates on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass toll stations without stopping, thereby minimizing pollution. Cost-saving: Reduces vehicle wear and fuel consumption by minimizing frequent starts and stops. Users also enjoy a 5% discount on toll fees. Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC systems faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" explicitly states the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the "13th Five-Year" comprehensive transportation development plan. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage, efforts will be made to promote ETC use for trucks and explore deeper integration of ETC systems with smart transportation developments such as vehicle-to-vehicle communication and vehicle-to-road coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of at least 10 meters to prevent automatic fee deduction for the wrong vehicle due to ETC device malfunction or absence. The recognition speed for ETC lanes is 20 km/h. Driving too fast may prevent the system from reading the vehicle's device information, leading to failed fee deductions. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will render the tag invalid. It can be taken to the bank where the ETC card was issued or to an expressway service center for inspection. If the issue is not due to human interference, reactivation is sufficient. When using a debit card linked to ETC, insufficient balance may cause fee deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pay with cash or card. Thick windshields may cause poor signal reception. This is especially important for vehicles that have had their windshields replaced after accidents or for those with modified front windshields.

How many points are deducted for brushing the line in the reverse parking test of Subject 2?

Brushing the line with the car body means the car body is out of line, which results in a deduction of 100 points, making the test unsuccessful. Other actions that also deduct 100 points include the car body crossing the line, failing to enter the parking space, stopping midway, not following the prescribed route, driving out of sequence, or exceeding the specified time. The full score for both subjects is 100 points, with evaluation criteria set for failure, deduction of 20 points, deduction of 10 points, and deduction of 5 points. The rules for the Subject 2 driving test for applying for a motor vehicle driver's license state that any mid-test stopping, rolling back, or not following voice prompts will result in failure. Additionally, the wheels or car body pressing the line will also lead to test failure. Many students encounter the issue of pressing the line during Subject 2 learning, and the most common mistake leading to failure is "pressing the line." The main reason for wheels pressing the line is that students fail to grasp the correct timing for steering. Besides missing the right moment to steer, another reason could be the steering speed not keeping up with the car's speed. Subject 2 deduction standards: Not wearing a seatbelt: deduct 100 points. Starting the engine without the gear in neutral: deduct 100 points. Not using the turn signal (including starting, changing lanes, overtaking, turning, or parking by the roadside); turning signal not used for more than three seconds (note this is easily overlooked!); forgetting to turn off the turn signal or using it incorrectly: deduct 10 points. Stalling once: deduct 10 points. Reverse parking: Not following the prescribed route sequence: deduct 100 points. Car body out of line: deduct 100 points. Failing to enter the parking space: deduct 100 points. Before reversing, if both front wheels do not pass the control line: deduct 100 points. Exceeding the 210-second time limit: deduct 100 points. Stopping for more than 2 seconds midway: deduct 5 points each time. Slope parking and starting: After the car stops, if the front bumper is not aligned with the pole line and exceeds 50 cm front or back: deduct 100 points. After the car stops, if the front bumper is not aligned with the pole line but does not exceed 50 cm front or back: deduct 10 points. After stopping, if the starting time exceeds 30 seconds: deduct 100 points. Wheels pressing the road edge line while driving: deduct 100 points. Rolling back more than 30 cm when starting: deduct 100 points. After stopping, if the car body is more than 50 cm from the road edge line: deduct 100 points. After parking, not tightening the parking brake: deduct 10 points each time. After stopping, if the car body is more than 30 cm but not more than 50 cm from the road edge line: deduct 10 points each time. Rolling back more than 10 cm but less than 30 cm when starting: deduct 5 points each time. Parallel parking: After the car enters the parking space, if the car body is out of line: deduct 100 points. Not using or incorrectly using the turn signal when entering the parking space: deduct 10 points. Exceeding the 90-second time limit: deduct 100 points. Car body touching the parking space edge line while driving: deduct 10 points each time. Wheels pressing the lane edge line while driving: deduct 10 points each time. Stopping for more than 2 seconds midway: deduct 5 points each time. Right-angle turn: Wheels pressing the road edge line: deduct 100 points. Not using or incorrectly using the turn signal during the turn, or not turning off the turn signal after the turn: deduct 10 points. Stopping for more than 2 seconds midway: deduct 5 points each time. Curve driving: Wheels pressing the road edge line: deduct 100 points. Stopping for more than 2 seconds midway: deduct 100 points. Driving without the gear in second or above: deduct 5 points.

What is a PCV heater?

pcv heater is the heater of the PCV valve, and the PCV valve is a valve in the crankcase ventilation system. The PCV heater is designed to prevent pipeline freezing. All car engines are equipped with a crankcase forced ventilation system. When the car engine is running, gases will enter the crankcase through the piston rings. The crankcase forced ventilation system can discharge the gases in the crankcase into the intake manifold, allowing these gases to re-enter the combustion chamber for participation in combustion. This not only avoids environmental pollution but also prevents excessive pressure in the crankcase. The crankcase forced ventilation system is very important for the engine.
