What are the reasons for the Baojun 560's locking horn not sounding?
2 Answers
Baojun 560 locking horn not sounding reasons are as follows: Horn contact erosion: If the horn is pressed for a long time, it can easily cause the horn contacts to erode and create impedance. The current passing through the electromagnetic coil weakens, reducing the electromagnetic attraction force, which fails to attract the armature to drive the diaphragm to vibrate normally, resulting in a hoarse or non-functioning horn. Poor sealing leading to moisture: Although the horn is internally sealed, if the sealing is not tight, moisture can enter during car washing or water vapor can accumulate in the internal space. This moisture can easily cause the contacts to get damp and fail to work properly. Poor terminal contact: If the insulation paint on the enameled wire ends is not cleaned properly or the crimping of the terminals is not secure, it can lead to malfunctions, causing the horn to work poorly. This type of fault is due to the quality of the horn and cannot be repaired.
As someone who has been helping out at auto repair shops for years, I think the common reason why the Baojun 560's lock horn doesn't sound is likely a blown fuse, especially when that little thing in the main circuit fails—the whole system goes silent. Additionally, aging or damage to the horn unit itself could be the issue, such as rusted contacts or internal component failure. Loose or short-circuited wiring is another potential problem; I've seen plenty of cars malfunction due to oxidized wire connectors. If it's a keyless entry system controlling the lock, the remote key's battery might be dead—try replacing it with a new one. If there's no response even with manual operation, check if the central door lock module is faulty. In such cases, I recommend first inspecting the fuse and battery yourself—it only takes a few minutes if it's not complicated. Otherwise, head to a professional shop immediately to avoid compromising the anti-theft function. Don’t forget to pay attention to these details during regular maintenance to prevent many headaches.
