What happens when the MIC and RST buttons on the car navigation are pressed?

1 Answers

MIC refers to the built-in microphone in the car navigation system. Pressing the MIC button can turn the microphone on or off. The MIC button is generally used in conjunction with Bluetooth calls. When you want to mute the microphone during a call, pressing the MIC button will prevent the other party from hearing you, but you can still hear them. RST stands for RESET, meaning reset/restart. When the car infotainment system freezes due to certain reasons, pressing the RST button can force a reboot of the system. Function of RST: For some car models, the RST button only serves to restart the system and does not have the function of restoring factory settings. For these systems, you need to enter the settings page after rebooting and then click "Restore Factory Settings" to reset the system. Function of restoring factory settings: For other car models, the RST button can restore factory settings. In this case, simply press and hold the RST button for more than 10 seconds, and the navigation system will automatically restore factory data. All personal files or settings in the navigation system will be erased.

Does the car throttle need to be matched after cleaning?

After cleaning the car throttle, it needs to be matched. The steps for cleaning the throttle are: 1. Turn off the ignition switch and remove the negative terminal of the battery; 2. Remove the throttle cable, intake hose, and screws fixing the throttle in sequence; 3. Clean the throttle with a cleaning agent, and use a cotton swab to wipe areas that are hard to reach. The throttle is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. The effects of a dirty throttle include: 1. Engine shaking during idle; 2. Insufficient power when driving; 3. Increased fuel consumption; 4. The vehicle is prone to stalling; 5. Emissions do not meet standards.

What is the function of a car's activated carbon canister?

The function of a car's activated carbon canister is to prevent fuel vapors from escaping into the atmosphere after the engine stops running. The working principle of the activated carbon canister: When the engine is running, the ECU controls the opening and closing of the carbon canister solenoid valve based on signals such as engine speed, temperature, and air flow to regulate the vacuum level in the upper part of the emission control valve, thereby controlling the valve's opening. When the emission control valve opens, fuel vapors are drawn into the intake manifold through the valve to participate in combustion. Notes on the activated carbon canister: Owners may encounter difficulty starting the engine due to an overfilled fuel tank, which could indicate a problem with the gasoline evaporation control system where the carbon canister is located.

What are the differences between China 5 and China 6?

The differences between China 5 and China 6 emission standards are as follows: Different emission standards: China 6 emission standards are more than 30% stricter than China 5. Excluding the influence of driving conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The China 5 standard was implemented nationwide on January 1, 2017, as the fifth stage of national motor vehicle emission standards. China 6 was implemented starting July 1, 2019. Different principles: During the China 5 stage, diesel and gasoline vehicles had different emission standards, but China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing departments: The China 5 standard was issued by the Ministry of Environmental Protection. The China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: China 5 is represented by 'V', while China 6 is represented by 'VI'. Different monitoring requirements for plug-in hybrid electric vehicles: Compared to China 5, China 6 has improved monitoring requirements for plug-in hybrid electric vehicles, including regulations on energy storage systems, thermal management systems, brake regeneration, drive motors, generators, etc. China 5 standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China 6 has two standards: China 6a and China 6b, as follows: China 6a standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM per kilometer driven. China 6b standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles are not currently restricted from normal use, such as travel or license plate restrictions, their resale value is significantly impacted. For truck owners who purchase vehicles on loan for cargo transport, the depreciation of the vehicle after paying off the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China 6 vehicles, which have a longer service life and more road rights, offer greater advantages.

What are the symptoms of damaged car spark plugs?

Car spark plug damage symptoms include: 1. Difficulty starting; 2. Low power; 3. Excessive exhaust emissions; 4. Increased fuel consumption. The working principle of spark plugs is: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block through the cylinder head. The electrode repeatedly generates electrical pulses, creating a high-voltage pulse that ionizes the air between the two electrodes, forming a spark and causing an explosion to ignite the air-fuel mixture in the cylinder, thereby starting the engine. Types of spark plugs include: 1. Standard spark plugs; 2. Projected insulator spark plugs; 3. Electrode-type spark plugs; 4. Seat-type spark plugs; 5. Pole-type spark plugs; 6. Surface-gap spark plugs.

Can a car run normally without an ECU?

Without an ECU, a car cannot run normally. The ECU is known as the brain of the engine. There are many sensors and actuators around the engine, and the ECU can collect data from various sensors. After processing, it can control the engine operation through the actuators. The ECU is a computer board fixed in the engine compartment, which can be found after opening the engine hood. The ECU's metal casing has certain waterproof properties and is equipped with heat sinks to help dissipate heat. When washing the car, avoid directly spraying water into the engine compartment with a hose, as this may damage the ECU and electronic sensors inside the engine compartment.
