Why Can't the Electric Car Key Unlock the Door?

The reasons why an electric car key cannot unlock the door include electronic lock damage, remote control damage, or insufficient battery power in the remote control. Here are the detailed explanations: 1. Electronic lock damage: If the electronic lock is damaged, it cannot receive the unlock signal or fails to initiate unlocking even after receiving the signal, resulting in the inability to unlock the electric car. In this case, repair is necessary. 2. Remote control damage: If the remote control cannot emit signals, it will lead to unlocking failure. Generally, two remote controls are provided when purchasing an electric car, and the spare remote control can be used. 3. Insufficient battery power in the remote control: Weak signals emitted due to low battery power in the remote control can cause unlocking failure.

What Are the Reasons Why the Ignition Device Cannot Start the Engine?

The reasons why the ignition device cannot start the engine are as follows: 1. The battery cannot hold a charge: If the vehicle has no power after being parked for just 1 day, aside from the battery's own sulfation (which prevents charging), it may be due to a leakage in the vehicle's wiring harness. 2. Short circuit in the coolant temperature sensor: If the engine fails to start after multiple attempts and the spark plug electrodes are very clean, it may be due to a short circuit in the coolant temperature sensor. 3. Clogged fuel filter: While driving, the vehicle's speed suddenly drops and continues to decrease until the engine stalls. After stalling, restarting may allow the engine to start, but the speed remains very low, and the engine cannot maintain operation, eventually stalling again and failing to restart. 4. Anti-theft system lock: When the anti-theft system is locked, the steering wheel cannot be turned, and the anti-theft indicator on the dashboard lights up. The control unit will interrupt fuel supply control but not the ignition. The engine cannot start, indicating that the steering wheel and ignition switch are locked by the central control. Applying force to rotate the steering wheel until it moves will cause the anti-theft system to automatically unlock, allowing normal startup.

Where are the reference points for reverse parking?

The reference points for reverse parking are as follows: 1. The steering wheel turning point: When the left rearview mirror aligns with the starting line (usually indicated by the instructor), immediately turn the steering wheel to the maximum. 2. Direction correction reference points: (1) As the vehicle is about to enter the parking space and the rear compartment approaches the parking line, observe through the rearview mirror to maintain a horizontal distance of approximately 30 centimeters between the wheels and both sides of the parking space. Adjust if the distance is too wide or too narrow. (2) After the vehicle enters the parking space, observe the left rearview mirror and the edge line of the parking space entrance. When the lower edge of the left rearview mirror aligns with the edge line of the parking space entrance, and when the edge line just disappears from view under the left rearview mirror, press the clutch and brake, stop the vehicle, and the reverse parking is completed.

What are the symptoms if one reversing radar is broken?

If one reversing radar is broken, it will not affect the entire system; only the broken one will not beep, while the other reversing radars will still function normally. Since the four probes of the reversing radar operate independently, if one is damaged, only the faulty reversing radar needs to be replaced. Below is some relevant information: 1. Probe positions: A reversing radar typically has four probes, installed on the rear or both sides of the car, with two on each side. 2. Overview: The reversing radar, also known as a reverse collision avoidance radar or parking assist device, is a safety aid for parking or reversing. It consists of ultrasonic sensors (commonly called probes), a controller, and a display (or buzzer). The reversing radar system alerts the driver to surrounding obstacles through audible signals or more intuitive visual cues, making reversing and parking safer.

Where to Start Reversing for Parallel Parking?

Subject 2 parallel parking starts with reversing from the right side. "Subject 2 tests both left and right parallel parking. Below are relevant details: 1. Subject 2 test content: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It refers to the field driving skill test, which includes five mandatory items: parallel parking, side parking, slope fixed-point parking and starting, right-angle turning, and curve driving (commonly known as S-curve). 2. Parallel parking sequence: The parallel parking test process involves reversing from the starting point (right) into the garage, driving from the garage to the return (left) point, reversing from the return point into the garage, and driving from the garage back to the starting point. After passing, the test continues to the next item.

What Causes Ignition Delay?

Here are the specific reasons for ignition delay: 1. Carbon deposits or component contamination: Throttle carbon buildup can affect the sensitivity to throttle and air intake, causing delayed or incorrect signals from the computer, resulting in failure to start the vehicle; The fuel injector is prone to accumulate sticky deposits, which can obstruct normal fuel injection, leading to poor gasoline atomization, thus causing ignition delay and difficulty in starting the car. 2. Inappropriate oil viscosity: For example, at very low temperatures, high oil viscosity can slow down oil circulation and cause mechanical dry friction, making it difficult to start the car. 3. Faulty carbon canister purge valve: The evaporation effect of gasoline is particularly strong after exposure to sunlight, and poor sealing of the carbon canister valve can easily lead to cylinder flooding or wet walls.
