How to Determine if the ABS Pump is Damaged?

Judgment Method: If the ABS pump is damaged, the brake pedal will feel very hard when pressed, and the sound will be strange, not the usual crisp and short sound. You can find a flat, uninhabited road, maintain a speed of about 60 mph, and slam on the brakes. If the brake pedal kicks back, it indicates that the ABS is functioning normally; if it doesn't kick back, it means the ABS is not working and there is a fault. If you remove the ABS fuse and apply the brakes at around 40 km/h, you will notice obvious brake marks on the vehicle. Here are the consequences of a faulty ABS: 1. If the ABS is damaged, there is a very serious hidden danger: in the case of emergency braking, the ABS function will not perform its role. 2. The ABS system prevents the tires from locking during sudden braking, avoiding accidents. If the ABS pump is damaged, the ABS warning light will come on, the anti-lock function will fail, and the brake pads will not reset. 3. If the ABS function is lost, you should use intermittent braking (pump the brakes) when braking, avoid sudden braking, and go to a professional repair shop for repair or replacement. 4. Modern cars are extensively equipped with anti-lock braking systems. The ABS not only has the braking function of a conventional braking system but also prevents wheel lock-up, allowing the car to steer while braking, ensuring directional stability during braking, and preventing skidding and deviation. It is currently the most advanced and effective braking device in automobiles.

What Causes Engine Smoke?

Reasons for engine smoke: 1. Incomplete combustion due to small fuel injection advance angle; 2. Slight water leakage in the cylinder liner or water presence in the fuel; 3. White smoke during cold starts, which disappears as the engine warms up; 4. Air-fuel ratio imbalance, decreased cylinder pressure, premature fuel injection timing, or failure of the smoke limiter on the injection pump; 5. Malfunction in the exhaust brake system; 6. Burning engine oil; 7. Wear of engine cylinder liners, piston ring sticking, misalignment, aging or deformation of valve seals, excessive valve guide clearance; 8. Engine oil entering the cylinder through the intake tract. Automotive engines are categorized into: naturally aspirated, turbocharged, mechanically supercharged, and twin-charged.

What Causes Engine Oil Leakage?

Reasons for engine oil leakage: 1. Damaged oil pan: As the container for storing engine oil, the oil pan will immediately leak oil once damaged; 2. Loose or stripped drain plug: If the vehicle is undergoing maintenance or an oil change, and the staff's negligence or improper operation causes the plug to loosen or strip, the engine will inevitably leak oil; 3. Excessive crankcase pressure: When too much oil is added, or the crankcase ventilation system fails, causing the mixed gas entering the cylinders to continuously accumulate, resulting in excessive internal crankcase pressure, the high-pressure gas will force the oil out from the seals, causing oil leakage.

What does 5S in automobiles refer to?

Automotive 5S refers to vehicle sales, parts sales and promotion, system information feedback, maintenance, and used car transactions. More detailed explanations are as follows: 1. Introduction: 5S refers to five subdivided services within after-sales service, a service approach primarily originating from Japan. 2. The key points of implementing automotive 5S are: Seiri (Sort), mainly referring to establishing the correct value awareness. Seiton (Set in order), referring to the correct method + organizational techniques. Seiso (Shine), referring to responsibility, mainly clarifying job responsibilities. Seiketsu (Standardize), mainly referring to institutionalization and assessment. Shitsuke (Sustain), mainly referring to long-term implementation.

What documents are required for vehicle pickup?

Vehicle pickup requires the vehicle registration certificate and ID card. Precautions for vehicle pickup are as follows: 1. Pay attention to the inspection of the vehicle's paint surface: When picking up the car, conduct a detailed inspection of the entire vehicle's paint surface. After the vehicle leaves the factory, during transportation and until the final sales process, the paint surface is most susceptible to damage. If the relevant staff is slightly careless, it may cause collisions or scratches to the paint. Park the vehicle in a well-lit environment for inspection, carefully observe whether the color and smoothness of the paint are uniform. Any repainted areas will inevitably leave traces to some extent. 2. Pay attention to checking whether the vehicle's seams are uniform: If the vehicle's body panels have been replaced or bodywork has been done, it is difficult to ensure the uniformity of the body seams. If the gaps between the seams are inconsistent or the transitions are not smooth and natural, it is likely to be an accident vehicle.

What Does Single Pedal in Cars Mean?

Single pedal in cars refers to a feature where one pedal can function as both the accelerator and brake. The specific details are as follows: 1. Introduction: Single pedal allows the vehicle's acceleration and braking operations to be completed with just one accelerator pedal. Of course, the single pedal mode does not mean that both the accelerator and brake are on the same pedal; there are still two pedals in reality, one for the accelerator and one for the brake. 2. Function: After activating the single pedal mode, when accelerating, the car moves quickly, but as soon as the accelerator is released, you can immediately feel the car decelerating very rapidly. This is because the single pedal mode in new energy vehicles involves so-called kinetic energy recovery. Kinetic energy recovery means that when the accelerator is not pressed, the energy from movement can be recovered and used for reverse charging.
