Can the Fragrance System Be Retrofitted?

Fragrance systems can be retrofitted. Here’s an introduction to fragrance systems: 1. Advantages: The fragrance dispenser is part of the vehicle’s air conditioning components, differing from any traditional form of car perfume. The fragrance dispenser absorbs fragrance via a micro-pump and then circulates it through the vehicle’s ventilation ducts to disperse the scent inside the car. It avoids the pungent smell of traditional car perfumes, delivering the fragrance at just the right rhythm—like bathing in the fresh air of nature, rich yet pleasantly soothing. 2. Features: The fragrance spray dispenser can adjust the interior scent according to personal preferences. It does not permanently alter the car’s interior odor, and the fragrance molecules do not settle on fabric surfaces or passengers’ clothing.

Why is the car remote not responding when pressed?

Car remote not responding when pressed may be due to: 1. The remote key battery is dead; 2. Poor contact or time control module failure; 3. The wireless receiving antenna in the car is aging; 4. The car uses explosion-proof solar film, which blocks the remote signal. There are three types of car remote keys distinguished by working methods: active working mode, passive working mode, and coil induction mode. The car remote key system consists of two parts: the transmitter and the receiver. The transmitter is composed of a transmission switch, transmission antenna, integrated circuit, etc. After receiving, the receiver will transmit to the electronic control unit, then decode it. If the input code is correct, it will output to the control circuit and execute the command.
