What Causes Transmission Function Limitation?

Why won't the Fit start?

Reasons why the Fit won't start: 1. The steering wheel is in a locked position: If the key won't turn, it's important to note that when parking, if the steering wheel isn't straightened and is at a larger angle (e.g., more than 30 degrees), the steering wheel will automatically lock as an anti-theft measure. This can make the key difficult to turn, preventing ignition. Solution: Apply force to turn the steering wheel while turning the key to quickly unlock it. 2. The gear isn't in P when parking: If the vehicle could start in D or R gear, the sudden movement upon ignition would pose a significant safety hazard. Therefore, for automatic transmission vehicles (AT, CVT, AMT), manufacturers preset this mode and repeatedly emphasize in the manual: Ensure the gear is in P when starting. 3. Low battery in the smart key for one-button start: Some models are designed with an emergency key slot. When the remote key's battery is low and fails to match correctly, inserting the key into the slot and pressing the start button can start the car. Note: Generally, one-button start vehicles require pressing the brake pedal when starting. Pressing the start button without stepping on the brake only activates the vehicle's electrical system. 4. Check the battery: If the vehicle has no power, pressing the horn can help determine this. 5. Check for fuel: The vehicle may not start if the fuel gauge shows below the red line, and fuel quality should also be considered. 6. Lack of antifreeze: Poor-quality antifreeze or excessive dilution can cause the engine to freeze and crack, preventing the car's water pump from operating, leading to starting failure and potential damage to other engine components.

What is the difference between VCU and ECU?

VCU is the electronic control unit (on-board computer) for electric vehicles, while ECU is the electronic control unit for traditional fuel-powered vehicles. Working principle of VCU: The VCU determines the driver's intentions by collecting signals from the accelerator pedal, gear position, brake pedal, etc. By monitoring vehicle status information (such as speed, temperature, etc.), the VCU processes this data and sends control commands for the vehicle's operating status to the power system and battery system, while also controlling the working mode of the vehicle's auxiliary electrical systems. The VCU also features diagnostic protection and storage functions for the entire vehicle system. Working principle of ECU: It controls the fuel mixture (air-fuel ratio) and spark timing (ignition advance and duration) based on feedback from sensors connected to the engine. The control of fuel mixture and ignition timing is quite complex. The ECU needs to gather data from multiple sensors to achieve optimal system control. The ECU must monitor ground speed, engine speed, crankshaft position, air quality (oxygen content), engine temperature, engine load (such as when the air conditioning (A/C) is on), throttle position, throttle change rate, transmission gear, exhaust emissions, and more.

What does the Bluetooth abbreviation in cars mean?

Car Bluetooth is referred to as CarBluetoothPhone in English, abbreviated as CBP. The benefits of using car Bluetooth include: Safe and healthy driving calls: Car Bluetooth allows drivers to control their phones without physical contact (even keeping both hands on the steering wheel), using voice commands to answer or make calls, ensuring driving safety. Using car Bluetooth significantly reduces radiation exposure and avoids irreversible damage to the ears caused by headphones. Convenient solution for conference calls: Car Bluetooth connects with the phone to form a convenient conference call system, delivering clear and unobstructed sound transmission.

How often is the C1 driver's license reviewed?

C1 driver's license does not require regular reviews, only when renewing the license. The first review is after six years, followed by another review after ten years. After the ten-year review, it becomes a long-term driver's license and no further reviews are needed. Drivers only need to submit a physical examination form annually after reaching the age of 70. Documents required for C1 driver's license annual review: Resident ID card (for those with ID cards from other provinces or cities, a temporary residence permit is also required) and a copy; original motor vehicle driver's license, which is the license you currently hold; three recent 1-inch white background color photos; physical examination qualification certificate from a district or higher-level hospital (these hospitals usually have physical examination points near the vehicle management office or traffic police station); applicants need to obtain the "Motor Vehicle Driver's License Application Form" at the vehicle management office and fill it out according to the instructions. Definition of driver's license: A motor vehicle driver's license is a legal document issued by the management department to individuals who are legally allowed to learn to drive motor vehicles, have studied and mastered traffic regulations and driving skills, and passed the examination, permitting them to drive certain types of motor vehicles.

What are the reasons for the compressor not starting?

Compressor not starting may be due to air not being completely evacuated from the system during installation, leading to ice blockage; or the compressor power supply is not properly connected or there is no electricity. Below are detailed explanations regarding compressor failure to start: Compressor ice blockage phenomenon: If air is not completely evacuated from the system during installation, ice blockage may occur, increasing the compressor's workload. The increased load raises the compressor's temperature, causing the refrigeration oil to deteriorate over time under high temperatures, failing to provide lubrication and cooling. This further elevates the compressor's temperature, reducing the insulation of the coils due to high heat, ultimately damaging the compressor. Solution: Ensure strict quality control during installation. Compressor power supply not connected or no electricity: Poor contact in the power cord socket, or the power cord is too thin or aged, or the power voltage is too low. Starting voltage for fixed-frequency air conditioners: 187V, voltage fluctuation range: 198-242V; starting voltage for variable-frequency air conditioners: 156V, voltage fluctuation range: 176-264V. It is recommended to install a voltage stabilizer in households. Additionally, bending or flattening of connecting pipes during installation can increase the compressor's workload. Solution: Check if the power cord is aged.
