What Causes the ABS Light to Illuminate in a Great Wall Pickup Truck?

ABS light illumination can occur in various states, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly illuminated (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and calculating the wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the contaminants from the wheel speed sensor and adjust the gap between the sensor and the tone ring to restore normal function. Cause 2: Loose connections between system wiring or poor contact in the ABS relay can cause signal issues, leading to system failure. Solution: Inspect wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple vehicle electrical components are in use, the battery voltage may drop below 10.5V. As engine speed increases, voltage rises, causing the ABS light to turn off. This can also occur if the ABS system 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; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains illuminated after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; loose wiring connections in the ABS hydraulic valve body; ABS control unit malfunction. Solution: Loosen and retighten the hydraulic valve body's grounding screw, cleaning the contact surface if necessary; check for enlarged terminal gaps; replace the ABS or ABS/ASR control unit. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS control unit detects a significant discrepancy between rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's specified tire and wheel rim sizes, as indicated on the fuel tank cap label. 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 downward to its limit, then release the pedal to complete self-positioning; replace the brake light switch if necessary. When the ABS warning light is illuminated, it is advisable to avoid continued 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, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.

How Big is a Car Fuel Tank?

Generally, the fuel tank capacity of small cars ranges from 35-45 liters, while medium-sized cars have a capacity of 55-75 liters. A full tank typically allows a driving range of about 500 kilometers. The size of the fuel tank correlates with the vehicle's displacement—larger fuel consumption requires a bigger tank, and vice versa. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank volume specified by car manufacturers is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to accommodate fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual fuel amount may exceed the marked tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with 'E' (Empty) and 'F' (Full). When the needle approaches 'E,' it indicates low fuel, while nearing 'F' means the tank is sufficiently filled.

Where is the middle seat belt in the back row of a car?

Generally, the middle seat belt in the back row is located on the rear ceiling, where you can see two different types of buckles. There are also two different types of sockets in the middle position, one on the left and one on the right. Seat belts are safety components used in equipment: They are straps used to ensure safety when riding aircraft or performing high-altitude work and artistic performances. The main materials are polyester, polypropylene, and nylon. Seat belts do not only refer to the webbing; besides the webbing, seat belts are also assembled with other components. One of the most important features of a car: Seat belts have become a primary consideration for drivers and passengers and are one of the most important features of a car. Traditional components for ensuring safe driving, such as rearview mirrors and side mirrors (traditional rearview systems), seat belts, AIRBAG (airbags), and ABS (anti-lock braking systems), are already familiar to most drivers and passengers and are commonly used in imported luxury cars.

Can a Motorcycle Be Equipped with a Dash Cam?

Motorcycles can be equipped with dash cams. Can be used as evidence: The video footage recorded by the dash cam can serve as evidence in traffic accidents or in cases of fraud, acting as favorable proof. It legally safeguards the rights of the driver, helping to avoid disputes. Additionally, it records the journey of the vehicle, making it an excellent choice for those who enjoy road trips. Records the entire driving process with video and audio: A motorcycle's dash cam can record both video and audio during the driving process. After installation, it captures the entire journey, providing evidence in case of traffic accidents. It's important to note that the video must not be edited when used as evidence; any edited footage will be considered invalid.

Is the Car Scrapped If the Engine Is Broken?

If the engine is broken, the car is not necessarily scrapped. A broken engine can be repaired, and if it cannot be repaired, a new engine can be installed as a replacement. Difference Between Recommended Scrapping and Mandatory Scrapping: Recommended scrapping suggests that the vehicle should be scrapped, but if the vehicle still meets the requirements for continued use, it does not have to be scrapped. Mandatory scrapping means the vehicle must, without exception, be scrapped. There are four criteria for mandatory scrapping: The vehicle has reached the prescribed service life; After repair and adjustment, it still does not meet the national standards for in-use vehicle safety technical requirements; After repair, adjustment, or the adoption of control technology, the vehicle still fails to meet national standards for in-use vehicle pollutant or noise emissions; The vehicle has not obtained the mandatory inspection compliance mark for three consecutive inspection cycles after the expiration of the inspection validity period.

Why does fuel consumption increase after replacing brake pads?

Brake caliper not retracting, apply some grease on the caliper pins. Maintenance: Brake pads need to be replaced every 3 to 6 kilometers. In a vehicle's braking system, brake pads are the most critical component, as the effectiveness of braking entirely depends on them. Brake pads are generally composed of friction material, steel backing plate, and adhesive heat insulation layer. The steel plate should also be regularly coated to prevent rust. When the brake pad indicator light comes on, it indicates that the brake pads need replacement. If this occurs, they should be replaced promptly. Brake pads also need replacement if their thickness is less than 0.5cm. Braking working principle: It primarily relies on friction. The vehicle uses the friction between the brake pads and brake discs against the ground to effectively provide sufficient stability and controllability in the braking system, thereby ensuring the driver's safety.
