How to Activate the Horn Sound When Locking a Changan Vehicle?

[Liam]

To activate the horn sound when locking a Changan vehicle, follow these methods: You can hold down all four window lift buttons, wait until the windows are fully raised, continue holding for 5 seconds, then release and lock the car to complete the reset. Alternatively, you can use a computer to access the vehicle's hidden settings and check the corresponding option to activate the locking horn. Extension: Working Principle: When the horn button on the steering wheel or elsewhere is pressed, current from the battery flows through the circuit to the electromagnetic coil of the horn relay. The electromagnetic coil attracts the moving contact switch of the relay to close, allowing current to flow to the horn. The current causes the electromagnet inside the horn to operate, thereby vibrating the diaphragm to produce sound.
