Why doesn't the horn sound when locking the MG6?
2 Answers
If the horn doesn't sound when locking the MG6, you can set the reminder function via the central console. If it still doesn't sound after setting, the following issues might be occurring: 1. Contact point erosion. Prolonged use of the horn can cause the contacts to erode, creating impedance. This weakens the current through the electromagnetic coil, reducing the electromagnetic force and preventing it from attracting the armature to drive the diaphragm for normal vibration, resulting in a hoarse sound or no sound at all. However, when the horn is pressed continuously, a momentary strong current can still pass through the impedance, causing intermittent functionality. 2. Short circuit caused by moisture due to poor sealing. Although the horn is internally sealed, if the seal is not tight, moisture or water vapor can enter during car washing, leading to damp contacts that fail to function properly.
Having driven for so many years, I've seen all kinds of minor issues, and the MG6's horn not sounding when locking is quite common. It might be that you've turned off the alert sound setting—many cars have an option in the system menu to enable or disable the locking sound. Check the vehicle settings on the central screen. Or, it could be a blown fuse; look for the horn's corresponding fuse in the engine compartment fuse box and replace it with a new one—that usually does the trick. Poor wiring connections can also be an issue—loose or corroded connectors can interrupt the signal. Additionally, low battery in the remote key might affect signal transmission; try replacing the battery. If there's no sound when locking, pay attention to whether the lights flash to confirm the lock, preventing misoperation and safety hazards. I recommend checking the user manual first. If that doesn't help, take it to a professional repair shop to inspect the wiring and the horn itself. Don't delay too long to avoid escalating the issue.
