How to Solve the Problem of Abnormal Noise in Sagitar Brakes?

What does the key-shaped symbol on the dashboard mean?

If a key symbol appears, it means the car cannot detect the key. This could be due to a malfunction in the car's receiving module, a failure in the key's transmitting module, or simply a dead battery in the key. Many cars are equipped with a keyless start system, which allows the driver to start the engine without using the key. After entering the car, the driver only needs to press the brake pedal and push the start button to ignite the engine. More details are as follows: 1. The remote key contains a transmitting module, and the car has a receiving module to detect the key. If the key's battery is dead, the car cannot detect it. 2. The remote key has a battery, which typically lasts 2-3 years. If the battery dies, it needs to be replaced. To replace the battery, simply pry open the key's casing. 3. Cars with keyless start usually have a designated key detection area inside the vehicle. If the key's battery is dead, placing the key in this area allows the car to detect it, enabling normal engine start.

What Causes the Squeaking Sound During Low-Speed Turns?

Low-speed turning squeaking may be caused by slipping of the power steering pump drive belt, unloading idle rotation of the steering pump, brake pads rubbing against the brake disc, or issues with the vehicle's drivetrain system. Below are detailed explanations: 1. The steering pump is driven by a belt. If the friction between the belt and pulley is insufficient, the belt will slip on the pulley, producing a squeaking sound. Possible causes include an overly loose belt adjustment, excessive wear on the pulley groove, or poor fit between a new belt and an old pulley. 2. When turning the vehicle, if the steering resistance exceeds the system's maximum pressure, the steering pump will unload and idle to protect the pump and steering gear. Typically, a "squeaking" unloading sound can be heard. This phenomenon is more pronounced when the steering fluid is contaminated, the steering filter is clogged, or there is air in the hydraulic system. The resistance encountered during low-speed or stationary steering is the greatest. Friction between the steering linkage and the power assist rod can also cause abnormal noises. In such cases, the vehicle should be placed on a lift for a thorough chassis inspection, ensuring to turn the steering wheel to full lock before observation.

How to Adjust the Idle Speed of Mitsubishi Pajero Carburetor?

Here is the introduction to the method for adjusting the idle speed of the Mitsubishi Pajero carburetor: 1. First, turn off the car, then tighten the idle adjustment bolt and loosen it by 1.5 to 2.0 turns. 2. Next, start the car and slowly loosen the throttle bolt to reduce the engine speed to a very low level, almost stalling. 3. Turn the idle adjustment bolt to raise the engine speed to the highest, repeat this process 2 to 3 times until adjusting the idle bolt no longer increases the engine speed. 4. Set the engine speed to 800 to 1000 RPM, accelerate, then release the throttle to check if the engine stalls. If it does not stall, it proves that the idle speed has been properly adjusted.

What Are the Symptoms of a Weak Car Battery?

The symptoms of a weak car battery include the inability to start the engine. Prior to this, you may also notice weakened vehicle lighting, a weak horn sound, sluggish starting, and the battery warning light illuminating on the dashboard. Below are the reasons that can lead to a weak car battery: 1. After turning off the car, if the engine is not running but you continue to use the vehicle's electrical equipment or external power devices for an extended period, this practice can harm the battery's lifespan. 2. Forgetting to turn off electrical devices such as headlights, air conditioning, or audio systems after shutting down the car. A single or occasional deep discharge may not have a significant impact, but frequent deep discharges over time can greatly affect the battery's lifespan.

Can You Add 92 Octane Gasoline After Filling Up with 95 Octane?

After filling up with 95 octane gasoline, you cannot add 92 octane gasoline. The specific reasons are as follows: 1. Normally, when the mixture of gasoline and air is about to combust in the engine, it is compressed into gas and then ignited by the spark plug to generate the power and energy needed for the car to operate. 2. The engine compression ratios for 95 octane and 92 octane gasoline are different. 95 octane gasoline is suitable for engines with higher compression ratios. If a higher compression ratio engine uses 92 octane gasoline, abnormal combustion will occur, leading to knocking. 3. Knocking not only damages the combustion chamber but also directly affects the normal operation of the engine, resulting in issues such as increased car noise, abnormal fuel consumption, and reduced driving power. In more severe cases, it may even cause engine damage.

What Does an Exclamation Mark on a Car Mean?

When an exclamation mark appears on the car dashboard, there are five possible scenarios: general fault, automatic transmission fault, brake system fault, abnormal tire pressure, and lighting fault. Below is a detailed analysis of these five situations: General Fault: A triangle with an exclamation mark inside indicates a general performance or component malfunction in the car. Common issues include parking sensor failure, fuel cutoff 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 transmission issue or low transmission fluid level. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circled parenthesis represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are required to prevent accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line below a parenthesis is the tire pressure monitoring warning light, which 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 a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
