What Causes the ABS Light to Illuminate After Vehicle Inspection?

ABS light illumination can occur in various states, with different causes and solutions for each state, as detailed below: 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 the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the 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 speed sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Check the 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 warning light turns off as the engine speed increases and voltage rises. This may also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off 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 grounding screw of the hydraulic valve body, cleaning the contact surface if necessary. Check if the connector gap has widened. Replace the ABS or ABS/ASR computer if needed. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals. This may also occur due to incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, typically found 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 linkage all the way down. Release the brake pedal to complete the self-setting process. Replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

Will Running a Red Light Always Be Captured by Electronic Police?

If there are cameras, all violations will be photographed. Whether it's running a red light while turning left or going straight, it is considered illegal. According to the relevant provisions of the "Road Traffic Safety Law," vehicles must obey traffic signals, including traffic lights, traffic signs, road markings, and the instructions of traffic police. If both the left-turn light and the straight light are green, going straight from the left-turn lane violates the designated lane rules. When the left-turn lane is red, running the red light will result in penalties. Here are some ways to avoid running a red light: Check the arrow light first, then the circular light: There are currently two types of traffic lights: arrow traffic lights and circular traffic lights. When an arrow light is present, checking the arrow light first and then the circular light can help avoid running a red light. Note: When encountering a circular red light, right turns are allowed. However, if the right-turn arrow is red, right turns are prohibited; otherwise, it will be penalized as running a red light. Brake in time: When the red light turns on, ensure the front of the vehicle does not cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture it, resulting in penalties for running a red light. If the front wheels have just crossed the stop line when the light turns red, do not proceed through the intersection; wait for the green light. Check the green light countdown before proceeding: When the green light flashes, if there is a countdown, use it to judge whether to proceed. If there is no countdown and the vehicle is close to the intersection with high speed, it may proceed to avoid running a red light due to delayed braking. If the speed is slow and the vehicle is far from the intersection, brake immediately to stop and avoid running the red light. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motorized vehicle or pedestrian signals, non-motorized vehicles and pedestrians must follow the motor vehicle signals. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not illegal in the following situations: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If captured by surveillance cameras while yielding, manual review will not record the red light violation. Even if recorded, you can apply for reconsideration with the traffic police. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights, the evidence of violation may be unclear, and no penalty will be imposed for mistakenly running a red light. Emergency situations: When rushing a critically ill patient to the hospital, multiple red lights may be run. After delivering the patient, provide proof from the hospital or the rescued person to the traffic police for verification. If confirmed, the violation records can be cleared. If possible, calling an ambulance is advisable to avoid accidents caused by running red lights. Traffic police instructions: During peak hours, traffic police may temporarily direct traffic at key intersections. Drivers must follow the gestures of the traffic police. The traffic police department states that according to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," when the yellow light flashes at an intersection, vehicles that have already crossed the stop line may continue. If the yellow light is already on and the vehicle continues to rush through, it will be considered running a red light if captured.

How long does it generally take to charge an electric vehicle?

Electric vehicles generally require 5 to 10 hours for charging. When the indicator light changes from red to green, it indicates that the battery is fully charged. It is advisable to continue charging for an additional 1 to 1.5 hours to allow the battery to absorb more energy. However, the charger should not be left connected to the AC power source for extended periods when not in use, and the charging time should not exceed 12 hours, as this may cause battery deformation and damage. Electric vehicles, also known as electric-driven vehicles, are powered by batteries and convert electrical energy into mechanical motion through components such as controllers and motors. The speed of these vehicles is adjusted by controlling the current flow. They are categorized into AC electric vehicles and DC electric vehicles.
