What are the exam subjects in driving school?

The exam subjects in driving school include the following four subjects: 1. Subject One: Road traffic safety laws, regulations, and related knowledge test; 2. Subject Two: Field driving skills test; 3. Subject Three: Road driving skills test; 4. Subject Four: Safe and civilized driving common sense. Additional information: 1. Subject One and Subject Four can be scheduled for retests without limit: There is no restriction on the number of times you can schedule the Subject One test and the safe and civilized driving common sense test. The safe and civilized driving common sense test can only be taken after passing the Subject Three road driving skills test. Those who fail can directly apply for a retest, and the previously passed road driving skills test results remain valid. 2. If you fail the test, the number of scheduled retests cannot exceed five times: During the validity period of the driving skills test permit, the number of scheduled retests for Subject Two and Subject Three road driving skills tests cannot exceed five times each (i.e., ten test opportunities in total). If you still fail on the fifth scheduled retest, the results of other previously passed subjects will be invalidated, and the student must start over from Subject One.

How Does the Crawl Control System Work?

Crawl control system works by allowing the onboard computer to intervene, controlling the brakes, throttle, and torque output. It can also release torque based on road condition feedback and electronically distribute braking force to all four wheels, ultimately preventing wheel slip. The driver only needs to steer and adjust the speed via the dashboard knob, without pressing the accelerator or brake. Related information: 1. The full name of the car's crawl mode is Low-Speed Cruise Driving Assist System, also known as the "fool-proof" off-road system. This system is particularly useful for inexperienced off-road drivers, as it helps them overcome challenging obstacles with ease. In low-range four-wheel-drive mode, activating the switch located on the right side of the gear lever engages the low-speed cruise assist, maintaining a speed between 1-5 km/h. Below the switch, there is a three-position rotary knob that allows the driver to toggle between three different speeds. 2. When climbing steep slopes or driving on special terrains such as snowy/icy roads, rocky paths, or sandy areas, the low-speed cruise assist system automatically controls the engine and brakes to maintain a stable low speed, ensuring excellent and stable passability. During driving, the driver does not need to focus on the accelerator or brake and can even remove their foot from these pedals. Simply concentrating on the road ahead and steering allows for easy navigation through difficult terrain, even reaching seemingly impossible heights.

How to Correct a Reversed Rearview Camera Display?

The method to correct a reversed rearview camera display is: 1. Engage reverse gear and locate the rearview camera settings in the system; 2. Enter the settings, find the rearview camera function, and turn it off to correct the display. The automotive rearview camera system consists of a wide-angle camera, a control unit for signal transmission, an MMI display, an information display control unit, a TV tuner, and a CAN data harmonization bus. Its function is to allow the driver to see the situation behind the vehicle on the display while reversing, ensuring safe reversing. The reasons for no signal in the automotive rearview camera are: 1. The data cable connected to the rearview camera is loose or poorly connected; 2. The rearview camera is damaged.

What Causes the Engine Warning Light to Illuminate in the Captiva?

There are primarily 7 reasons why the engine warning light illuminates in the Captiva: Sensor Malfunction: The sensors in question include those for coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, which triggers the engine warning light. Fuel or Oil Quality Issues: Failure to use the fuel or oil specified by the manufacturer may cause engine wear, leading to the illumination of the warning light. Poor Combustion of Air-Fuel Mixture: Poor combustion can result in engine carbon buildup or knocking. Once detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as faulty spark plugs, defective ignition coils, fuel pump failure, or clogged fuel lines can all cause poor combustion of the air-fuel mixture. Turbocharger Problems: The intake boost piping or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If the vehicle's intake system is compromised, it may lead to clogged engine pipes, and in severe cases, the engine warning light will illuminate. A dirty or uncleaned air filter can cause intake issues. Exhaust Problems: Exhaust system faults can also trigger the engine warning light. Common causes include faulty rear oxygen sensors, catalytic converter issues, or problems with the exhaust camshaft and bearings. The catalytic converter is the most frequent culprit. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can all contribute to catalytic converter failure. Anti-Theft System Malfunction: If the vehicle's electronic anti-theft system fails or if the anti-theft controller is incompatible with the engine ECU, the anti-theft system may prevent the engine from operating normally, accompanied by the illumination of the engine warning light. If the engine warning light illuminates, follow these steps: First, check whether the engine is running normally. Look for symptoms like shaking or black smoke. If present, avoid restarting the engine. Note: Never restart the engine if the warning light is red. If the engine can be started, turn it off and wait 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position (without depressing the clutch). The vehicle will perform a self-diagnostic check upon powering up. Wait 5-10 seconds to see if the warning light turns off. If the warning light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to retrieve trouble codes, identify the issue, and perform targeted repairs.

What Causes the ABS Light to Appear on the Dashboard?

ABS light can illuminate in various states, and different states have different causes and solutions. The details are as follows: State 1: ABS warning light stays on (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose system wiring connections or poor contact in the ABS relay, leading to system failure. Solution: Check wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. The ABS light turns off as the engine speed increases and voltage rises. This may also occur due to insufficient power supply voltage to the ABS system, such as poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, charging system, and power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and turns off only when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body wiring connector; ABS computer malfunction. Solution: Loosen and retighten the hydraulic valve body's grounding screw, cleaning the contact surface if necessary. Check for enlarged gaps in the connector; replace the ABS or ABS/ASR computer if needed. State 4: ABS warning light illuminates during high-speed driving. Cause: The ABS computer detects a significant difference between rear and front wheel speeds during high-speed driving; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal and manually push the brake switch lever down completely, then release the pedal to reset its position. Replace the brake light switch if necessary. If the ABS warning light is on, it is not recommended to continue driving. A lit ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, locked wheels can cause the vehicle to skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.
