The reason the remote key cannot open the trunk is insufficient power of the remote, resulting in a weak signal that the receiver cannot detect. The basic components of a remote key consist of the following two points: 1. Transmitter: Composed of a transmission switch, transmission antenna, integrated circuit, etc., it contains an identification code storage circuit and an amplitude modulation circuit, with a button-type lithium battery installed on the opposite side of the circuit. The transmission frequency uses radio waves, and pressing the transmission switch button once sends a signal. 2. Receiver: After the transmitter sends the identification code using shortwave modulation, it is received by the car's shortwave antenna and enters the shortwave high-frequency amplification processor of the receiver's electronic control unit via a distributor for demodulation, where it is compared with the demodulator's identification code.

What do the S and L gears mean in the Fit?

The S gear in the Fit refers to the sport mode of the transmission, while the L gear stands for low gear mode. The S gear shifts at higher RPMs, and the L gear is typically used for climbing steep slopes or driving on snow. Below is more information about the S and L gears: 1. In S (Sport) mode, the transmission can shift freely. While driving, simply push the gear lever into the S position. This mode is commonly used for climbing hills or quickly accelerating to overtake. 2. The L gear is a low forward gear, used when descending mountains or long downhill slopes. It restricts the car to automatically stay in low gear, allowing the engine to assist in braking during downhill driving. This prevents the driver from having to brake continuously, which could overheat the brake pads and pose a danger.

What does an exclamation mark inside a Skoda bulb indicate?

Yellow bulb with an exclamation mark is the light fault indicator, indicating that there is a fault with the vehicle's lights. Solution: Visit a 4S store for inspection and repair as soon as possible, or you can perform a self-check. Focus on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. The exclamation mark is a common fault indicator in vehicles. Besides the yellow bulb with an exclamation mark, there are four other forms of exclamation mark indicators: an exclamation mark inside a triangle, an exclamation mark inside a yellow gear, an exclamation mark inside a circled bracket, and an exclamation mark inside a bracket with a horizontal line below. Below is a detailed analysis: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the vehicle's general performance, components, or functions. 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 store for inspection to identify the source of the fault. Automatic Transmission Fault: An exclamation mark inside a yellow gear. This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant level below the normal range. Transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circled bracket. This represents a brake system warning, primarily indicating brake system failure or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire Pressure Anomaly: An exclamation mark inside a bracket with a horizontal line below. This represents the tire pressure monitoring warning light, which illuminates when the vehicle's tire pressure is too low. Check the tire pressure and restore it to the normal range.
