What Happens If You Don't Replace Leaking Shock Absorbers?

What Does the Yellow Exclamation Mark Symbol Mean?

When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Faults: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a problem with the transmission or that the transmission lubricant level is below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside parentheses represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling that a car light has malfunctioned. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. There is also a red exclamation mark inside a circled parenthesis, which represents a warning for the braking system, primarily indicating a brake system malfunction or low brake fluid level. The braking system should be inspected immediately to avoid accidents.

Is Scratching the Wheel Hub When Removing Tires Unavoidable?

Scratching the wheel hub when removing tires can be avoided. Techniques to avoid scratches: When replacing tires, it is possible to prevent the wheel rim from being scratched. When using a tire changer to replace tires, technicians usually apply special lubricant on both the wheel rim and the tire. This not only protects the wheel rim and tire but also effectively prevents scratches. The importance of tires: Tires are a crucial component of a car, being the only part that comes into direct contact with the ground. They are essential for the vehicle's driving stability and safety. As rubber products, tires age over time with prolonged use, which is why they need to be replaced regularly.

What are the phenomena and causes of crankshaft axial movement noise?

Phenomena and causes of crankshaft axial movement noise can be divided into two situations: axial and radial. Axial phenomena and causes: Excessive axial clearance causes vehicle jerking during startup, sometimes accompanied by metallic impact sounds. Diagnosis involves using a pry bar under the vehicle to check for play at the crankshaft pulley. The root cause is typically excessive wear of crankshaft thrust washers requiring replacement. Radial phenomena and causes: Metallic impact sounds and engine vibration occur during acceleration/deceleration. Using a stethoscope (automotive diagnostic stethoscope or 2-3 foot long copper pipe/iron rod), listen near the engine bottom. Subsequent inspection involves checking engine oil for metal particles - 90% probability indicates excessive crankshaft bearing clearance causing abnormal noise. For precise diagnosis under favorable conditions, removing the oil pan provides more accurate assessment.

Why is the idle speed needle not moving?

The reasons for the idle speed needle not moving may include excessive engine carbon deposits or instrument failure. The specific causes and solutions are as follows: Excessive engine carbon deposits: When engine fuel does not burn completely, it easily forms carbon deposits. Excessive carbon deposits can lead to reduced engine power because the carbon deposits adhere to the spark plugs, diminishing their ignition capability and failing to generate sufficient power, causing the idle speed needle to stop moving. Solution: Clean the carbon deposits. Instrument failure: The fuse of the instrument panel may be blown, or the wiring may be loose or short-circuited, causing the idle speed needle to stop moving. Solution: Perform repairs.

What are the causes of abnormal headlight control?

The causes of abnormal headlight control may include bulb damage, fuse blowout, switch or relay damage, and circuit faults. Introduction to headlights: Headlights, also known as automatic sensing headlights, are equipped with a photosensitive control system for the front lights. The central intelligent control box determines the changes in light brightness through light sensors, thereby controlling the automatic activation or deactivation of the headlights. Automatic headlights only function when the light control is set to the automatic mode. Function of headlights: The main function of headlights is to illuminate the road ahead and to alert pedestrians or other vehicles to the presence and position of your vehicle. Therefore, automatic headlights can activate when ambient light is insufficient, ensuring driving safety.

Is the inspection pass label still required for new car registration?

New car registration no longer requires the affixation of an inspection pass label. Vehicle inspection pass label: This is a certification issued by the vehicle management office after a motor vehicle passes the periodic safety technical inspection as required by national regulations, proving its safety performance. According to legal provisions, motor vehicle drivers must undergo regular inspections at the traffic management departments of public security authorities in accordance with laws and administrative regulations. Documents required for new car registration: ID card, vehicle certificate of conformity, vehicle parameter sheet, second and fourth copies of the car invoice, vehicle purchase tax, car insurance policy, purchase invoice, vehicle certificate of conformity, ID card or organization code certificate and its copy of the invoice issuer, compulsory traffic insurance policy, tax payment certificate, and temporary residence permit for non-locals.
